Can you influence your biological age?

Claus Hancke

29 January 2024

The short answer is: “Yes. Of course you can.”
The difficult question is: “How much?”

It is not rocket science to figure out that you reduce your chances of a long and good life if you sit in solitude on the sofa all day, smoking, eating chips and drinking cola, sleeping too little and weighing too much. You age faster. It seems to be common knowledge.

Therefore, it is right up our street to start changing such habits if you want to increase the chance of a good and long life, i.e. slow down the speed at which you age. This is what is popularly called lowering one’s biological age.

This question is brought up to date by a popular Danish TV broadcast with mention of research done at the Danish state hospital, Rigshospitalet, where researchers are trying to influence the rate of aging so that you age more slowly or may become a little younger from a biological point of view.

And here they have also tackled the above-mentioned, specific bad habits, after which they “calculate” the biological age before, during and after the intervention.

So how do you calculate this biological age? It is, of course, a purely theoretical age, based on expected remaining life, calculated from an algorithm which is constructed according to the parameters that are now believed to affect life expectancy and the speed of aging in 2024.

The same persons may have a completely different biological age in 5 years, when science has exposed completely different parameters that affect life expectancy even more strongly. This particularly concerns various blood tests, i.e. biochemical parameters, where we are constantly getting smarter.

One of the most reliable measurements of a person’s biological age is probably the measurement of the remaining telomeres in the genetic material of the cell nuclei. These telomeres shorten during cell division, and when we have no more, we die. Many international researchers have been interested in this for the past 20 years, including the Swedish professor Urban Alehagen, who, as mentioned in a previous newsletter has researched the life-extending effect of Q10 and selenium.

In the above-mentioned TV broadcast, the various lifestyle measures have been supplemented by taking a pill with Nicotinamide Riboside, which supports the cells’ energy production.

Many have asked me what it is, and to bring clarity to the many abbreviations and biochemical contexts, I have made a small presentation which can be viewed on Youtube. It is difficult to describe these biochemical processes in a newsletter, which is why we supplement with this video.

Nicotiamide Riboside is only one of many forms of vitamin B3, all of which contribute to increased energy production in the cells’ power plants, where the cell makes its energy, the so-called mitochondria.

We consume vitamin B3 as nicotinic acid or nicotinamide, after which it is converted to nicotinamide riboside (NR) and then to nicotinamide mononucleoside (NMN), which is then converted to what it is all about, nicotinamide adenine dinucleotide (NAD) in the cells .

(NAD has the property that it can alternate between two oxidation stages NAD+ and NADH, thereby contributing to energy production together with Q10.) This takes place in the inner membrane of the mitochondria.

Whether you consume NR or NMN or Nicotinamide is a question of how far down the synthesis pathway you want to start. Overall, the end result will be roughly the same, just with a difference in the amount of NAD formed.

I apologize for the many abbreviations and the somewhat difficult explanation, which I hope my little video can make up for.

Supplements can be exciting and good, and even life-prolonging. But don’t forget the most important things:

A healthy diet, daily exercise, a good night’s sleep, avoid being overweight and stick with your friends from your youth. You won’t get new ones. Stop smoking and moderate your alcohol consumption. It all helps to raise your quality of life and slow down the aging process.

Take care of yourself and others.

Patent or not, that is the question

Claus Hancke

November 16, 2023

Is it really necessary to have a patent and billions of kroner before the media takes an interest in sensationally good results?

The other day in the newspaper Politiken, you could read an article (1) about Ozempic and Wegovy /Semaglutide, including an interview with Professor Jens Søndergaard, who stated that a recent study from the Cleveland Clinic had shown a 20% reduction in serious cardiovascular events after 4 years of treatment, which is such a great medical breakthrough that he had never seen anything like it, and compared it to the discovery of penicillin. -This is really great.

Semaglutide costs DKK 2,400 per month and has side effects in the form of upset stomach and nausea.

The result is quite impressive, even if it is a relative risk reduction rather than an absolute risk reduction. But there are now other scientific studies from this year that have shown far more impressive results.

What if there were a treatment that after 4 years showed a reduction in cardiovascular mortality of over 50% at a price of DKK 369. per month and completely without side effects? … What??
Yes, that is precisely the conclusion of the 10-year follow-up of the 2013 study (2) of Selenium and Coenzyme Q10 in combination.

The study (3) was previously described in the Vitality Council’s newsletter of 23 April 2023. However, that is not what I want to focus on here. It is rather the selection of news in the media that I want to discuss.

What really surprises me is that a risk reduction of 20% for cardiac events draws huge headlines and benevolent admiration whereas an equally valid study, which even shows a reduction in cardiovascular mortality of over 50%, is not even mentioned in the same newspapers -and you can’t deny the quality of this study.

Is it because it’s too good to be true that the media don’t want to bother writing about the scientific article, or does it absolutely have to be an expensive prescription drug with side effects before it’s interesting?

Actually, Professor Urban Alehagen also doubted his own results, which is why he analyzed them again and again from different sides but came to the same result.

And he is not the only one, as numerous previous studies have shown consistent increased survival with selenium and/or Q10.

Senior physician Svend Aage Mortensen at Rigshospitalet published several fine studies (4) of Q10 against heart failure but without their winning any resonance in the very orthodox medical profession.

Substances such as Coenzyme Q10 cannot be patented. Is that where the dog is buried? After all, a patent opens up possibilities for absolutely exorbitant earnings and the resulting marketing, press coverage, etc., just as there are funds for further research, publications, press, etc. -A self-reinforcing wheel that just goes faster and faster.

Substances that cannot be patented easily drown in the media stream because there is no great interest when there is no big money involved. But that is precisely why one should be even more interested in the serious research that takes place with these unpatented products. Professor Alehagen’s studies have clearly shown that an expensive, patented product is not necessary to halve the risk of dying of cardiovascular disease.

It is simply incredible that the selenium and Coenzyme Q10 study has not found a place on the front pages of the media.

Take care of yourself and others.

Mink panic in Denmark

Claus Hancke

November 5, 2020

As written in the first Covid-19 newsletter on May 6 (1):

”A vaccine may be excellent, but firstly, it takes at least a year before we have it, and secondly, a vaccine can never keep up with a virus in the many mutations that make its immune profile so varied that a vaccine quickly becomes obsolete as we have seen with the flu vaccine. The only thing that can keep up in response against a virus’ mutations is a well-functioning immune system in the individual.”

And now what has been expected has happened, namely a mutation that spreads a lot of panic, costs 17 million mink their lives, 1,100 mink farmers their livelihood and perhaps life’s work, 6,000 jobs, and Denmark 10 billion kroner in export revenue.

Many ask if this is now also necessary, and international researchers wonder about the Danish reaction, as they cannot see that this mutation is more dangerous than so many other mutations.

In the defense of the authorities, it can be said that 17 million mink do constitute a very serious pool of infection within the country’s borders, and, on mink farms, the virus can persist for years and can perhaps mutate into dangerous varieties.

The current “cluster-5 variant” found in mink is, according to authorities, no more dangerous than the “original Wuhan variant”, but is still considered dangerous by the Serum Institute.

Not more dangerous for humans, but dangerous for the vaccine.

It is feared that this variant will weaken the effect of a future coronary vaccine.
But there will be more mutations. It will continue. If not from domesticated mink, then from forest marten, ermine (stoats), otters, and ferrets. Or what about a variant of the dreaded bird flu that becomes contagious to humans? It is a far more dangerous situation.

If we continue with this eternal focus on vaccines and only vaccines, we can run in circles for decades and constantly have to jump from one position to another to escape new mutant variants.

At the EU level, however, hard work is underway to make human survival dependent on vaccines (2) so that the individual’s immune system can only be strengthened in this way and not by natural infection.

This is a dangerous path to take, and it can result in an inflicted immunological handicap that weakens humanity’s ability to counteract precisely the many mutations that microorganisms undergo in their own evolution.

One can imagine the situation that one day we will be exposed to a life-threatening pandemic like in 1918, which kills millions of people the year before we can get a vaccine. (The current pandemic has not increased overall mortality.)

We therefore need to ensure that the human population’s basic immune system is optimal. It may be possible to do so, but it requires openness to new thinking.

When we focus exclusively on the Covid-19 epidemic, there is an almost overwhelming number of studies that identify vitamin D deficiency as a significant risk factor for infection.

Most recently, three days ago (November 2), a new study (3) was published describing Covid-19 survival in the elderly as a function of their vitamin D intake.
There were 77 Covid-19 patients aged 78 – 100 years equally distributed between men and women. All were admitted to a geriatric emergency department at Angers University Hospital in France from March to May in 2020.

One could see the difference between the three groups: Group 1 (n=29) had taken vitamin D continuously for at least one year, group 2 (n=16) had not taken anything but had received a bolus dose of vitamin D on admission, and group 3 (n=32) had not received vitamin D.

The thrtee groups were comparable over a wide range of potentially confounding factors. The average age of the study participants was 88 years.

Researchers evaluated 14-day mortality and found that 93% survived in group 1, 81% in group 2, and 68% in group 3.

With group 3 as the reference group (Hazard Ratio: 1), group 1 thus had a hazard ratio of 0.07, and group 2 had a hazard ratio of 0.37.

Thus, group 1 with a history of solid vitamin D supplementation had significantly better survival than group 3, which had not taken vitamin D supplements.

Group 2, which received a bolus of 80,000 IU vitamin D at admission, had better survival, but the difference from group 3 survival was not statistically significant.

The conclusion of this study was thus that regular supplementation with vitamin D is associated with less severe COVID-19 disease and better survival in frail elderly individuals. The detailed figures can be seen in the reference below (3).

Study after study of vitamin D’s efficacy has been added to the basket over the last six months, and the studies are all identical. How many studies do we need?

When these studies are combined with the hundreds of previous studies on immune system weakening in the absence of vitamin D and with the even specific studies and a meta-analysis on lung infections like SARS, then one must again ask: How many studies does it take before the authorities will advise vulnerable groups to take vitamin D or at least to have their vitamin D levels in their blood measured?

Many studies (references 4-19) show that one can safely and effectively optimize the population’s resistance and survival of Covid-19 by taking sufficient vitamin D to reach a blood concentration of at least 75nmol / l.

This blood vitamin D concentration can most often be achieved with a daily dose of 80 – 100 micrograms.

If one also supplements with the other well-documented supplements, which have been mentioned in the previous newsletters, then we can get to the point that the general resistance of the population has increased. We need to increase the population’s resistance against the upcoming mutations of Covid-19 and also against other epidemics, which may even be dangerous.

But, for now, remember to wash your hands and keep your distance.

Take care of yourself and others.

Update on Corona virus

Claus Hancke

August 26, 2020

Since the last newsletter from May 28, things have gone well here in Denmark.
On the other hand, viruses have become widespread, especially in those countries that have not taken the spreading of infection seriously.
In the past month, however, localized infection clusters have emerged in various places here in Denmark as well, especially in immigrant communities.
The reasons for this have been mentioned in the previous newsletters, whose advice is still valid, so I will not repeat it here, but instead focus on what has happened in the last 3 months.

Studies
In a literature study(1) from Norwegian, Russian and Swedish public health institutes six researchers have concluded that early intervention with Zinc, Selenium and Vitamin-D can alleviate the course of the disease, and virtually prevent the cytokine storm, which is the process responsible for the destruction of tissues, microthromboses, inflammation, etc. -the whole cascade that can take the life of the Covid-19 sick persons.

An almost simultaneous study(2) from Germany analyzed Serum-Selenium and Serum-Selenoprotein P, and both values were significantly lower in those who did not survive Covid-19.
(Selenium: 53.3 ± 16.2 vs. 40.8 ± 8.1 μg / l, Selenoprotein-P: 3.3 ± 1.3 vs. 2.1 ± 0.9 mg / L p<0.001). These results must be said to be highly relevant in our country, where we consume so little selenium. This study falls nicely in line with the former study.

On August 3, an article was published in the Lancet(3) which strongly calls for increased intake of vitamin D based on solid literature reviews.
This also falls in line with the first study mentioned above.

And, finally, there is a meta-analysis(4) of the role of vitamin D in the development of acute respiratory infection. It includes 30,000 people in controlled trials (RCTs), and has shown significantly reduced risk of acute respiratory infection already at 10-25 µg of vitamin D daily.
This confirms a previous meta-analysis(5), which also found a significant inverse correlation between the risk of acute respiratory infection and the vitamin D content in the blood.
All of the above studies are nicely in line with the advice mentioned in the five newsletters from May.

Authorities distribute vitamins
Azerbaijan has registered 35,000 Covid-19 cases in a population of 10 million. Of these, 1,800 were hospitalized and 508 died.
Here, the Ministry of Health has provided more than 3,500 Covid-19 patients with a free “medicine package” containing: Vitamin C, Vitamin D, Magnesium, Selenium, Zinc and Paracetamol.
The idea is then that the patients stay at home and treat themselves there.
Every day they are then contacted by the local hospital clinic and have to answer a series of questions, just as the doctor checks that they are taking their pills.
So far, a significant reduction in the number of hospitalizations in this group has been observed(6).

You can only shout cheers when you see authorities who can think outside the box and dare to start such a project. My guess is that the trend will continue and that home treatment will continue to reduce hospital admissions in Azerbaijan.

The idea is not bad because you initiate a completely harmless treatment of a, for some people, -dangerous disease.
But why wait until they get sick?

With timely care, one can improve the immune system of the entire population if one simply provides information about these supplements and their significance.

What could be done here in Denmark is to provide subsidies to the vulnerable groups, especially residents of the country’s nursing homes, who are completely dependent on the public perception of vitamins and minerals. If their own doctor does not prescribe a vitamin supplement, then residents are often denied help to get the supplements, despite their own desire. They are completely dependent upon the doctor’s knowledge or lack thereof. I think Danish authorities and medical staff would be shocked if we measured the level of vitamin D in the country’s nursing home residents.
If you do not want to use public funds to donate these subsidies to the residents, then you can at least make sure that both residents and their relatives are informed.

These newsletters on Covid-19 are unfortunately necessary as this knowledge and the scientific back-up are neglected in the public advice to the Danish population.

Take care of yourself and others

Be prepared for the next Corona epidemic

Claus Hancke

The population is not

May 29, 2020

The Corona is spreading more slowly now, and, here in Denmark, Covid-19 is gradually infecting fewer and fewer people and we are more aware of protecting ourselves against it.

There have been good effects from keeping our distance and from maintaining good hygiene in which we have all been well instructed.

Much to the surprise of the Danish Serum Institute, less than 2% of the Danish population has had the disease, and only a few of these individuals may have obtained immunity to SARS-CoV-2, which the virus is called.
This means that more than 98% have not been infected and are completely without immunity. So forget about herd immunity.

The Danish population is just as vulnerable it was were in March when it all started.

Let’s try to summarize what we know and what we can do about it.

What do we know now?
SARS-CoV-2, which is the virus responsible for the current Covid-19 pandemic, is characterized in that it – like the influenza virus – triggers a reaction with the release of a number of signaling molecules such as interleukins, interferons, and lymphokines.

When this release is powerful, it is called a “cytokine storm”, and with Covid-19, it is so powerful that immune cells begin to damage the tissues where the process is taking place, and, in this case, it is primarily the lung tissue that is damaged.

During the cytokine storm, a violent inflammatory response and increased release of free oxygen radicals are created, which further damages the lung tissue due to the subsequent inflammatory microcoagulation seen in the pulmonary vessels. Adding too much oxygen at this stage will only aggravate the situation, which several anesthesiologists have experienced when Covid-19 patients’ conditions worsen when they are put on a respirator.

What can we do about it
Thus, it is primarily about attenuating the fatal cytokine storm.
Here vitamin D, magnesium, selenium, and vitamin C are particularly important as they specifically inhibit this cytokine storm and the subsequent inflammatory microcoagulation in the pulmonary vessels.
If the level of these essential substances in the body is high enough then you will have a subdued cytokine storm and thus attenuated symptoms, as seen during influenza infection. Fresh extract of Coneflower (Echinacea) has also been documented in several scientific studies to effectively inhibit this cytokine storm.

It should be obvious to protect ourselves by promoting such harmless and inexpensive remedies, but unfortunately in the medical and pharmaceutical world, one tends to stare blindly at the most expensive solutions.
Medical professionals were first intrigued by the antiviral drug Remdesivir, which could shorten the disease period of Covid-19 from 15 to 11 days. This fascination has now been replaced by a new one, another drug, an experimental cancer drug, Bemcentinib that may prevent viruses from entering the cells. A phase II trial is underway for 120 people, and we hope we will be able to get the result in a few months.

Well, it is excellent that medical professionals try to find a medicine that can help in this situation, but is it absolutely necessary to find a new, expensive medicine with side effects, when there are other far cheaper options without side effects?

The long awaited vaccine
While all this is going on, the pharmaceutical industry is working full speed on a vaccine. A vaccine against an RNA virus is very difficult to make, and using a vaccine is especially problematic because viruses constantly mutate and thereby often change the immune response.

No vaccine has ever been safety-tested, in the same way that medicine is tested, and this is a bit problematic because in recent years, the industry has started to add substances whose purpose is to stimulate the immune system for effective antibody formation. And stimulating antibody formation is good enough, too, but the safety of these substances has never been investigated. In Denmark, the use of mercury (thimerosal or thiomersal) in childhood vaccines was stopped from 1992 and in influenza vaccines from 2004, with the exception of the vaccine in 2009, which was an embarrassing exception. The toxic mercury should never be used again for human use – neither in the teeth, for that matter.

But in recent years aluminum has been added in the form of nanoparticles as well as squalene emulsions. These adjuvants have not been safety tested. It has just been noted (WHO has noted) that the number of side effects is not greater than is usually seen with vaccination. Aluminum is a neurotoxin, but it has been used in vaccines in the form of various aluminum salts since 1930, so in that form it probably isn’t particularly harmful. The problem is that nanoparticles are now being used that cannot be stopped by a cell membrane. They can penetrate all tissues.
It cannot be ruled out that it is safe to use these additives. It’s just never been investigated.

It should be a simple task to make a study with each of these ingredients against a real placebo such as brine.
We have many excellent vaccines, so let’s not be vaccine deniers. Let’s welcome a SARS-CoV-2 vaccine when it arrives, and then just hope it is properly safety tested. Of course, this hope becomes a requirement if we are to be mandatory vaccinated.

Of course, the Coronavirus will return
When and how bad we do not know, but it will come.
As mentioned in the Vitamin C newsletter, one of Europe’s experts in Covid-19, Professor Christian Drosten from the University of Berlin, has stated that the second wave could be tougher than the current one.
And since more than 98% of the Danish population is without immunity against it, we should not sit with our hands in our laps and wait for a vaccine.

We need to be proactive.
We need to make sure that we have enough of the nutrients that can reduce the risk of our getting sick, and especially the nutrients that can dampen the cytokine storms, so that we get a mild course of illness if we get sick anyway.

Especially old people and people who eat only very little, who may also be weakened by chronic disease, will do well by supplementing the diet in order to be well equipped with an optimally functioning immune system as the next virus threat approaches.

An appropriate daily dose for a normal-weight adult will typically be:

  • Vitamin A: 1-2 mg
  • Vitamin B6: 4-5 mg
  • Vitamin C: 2-3,000 mg
  • Vitamin D3: 75-100 µg
  • Selenium: 100-200 µg
  • Zinc: 20-30 mg
  • Magnesium: 200-300 mg

Note: The low dose is for those weighing less than 70 kg (155 pounds / 11 stones).

If you start now, you will be prepared in the fall. This is an obvious strategy for the country’s nursing homes.

This is the fifth and final Covid-19 newsletter.

Unfortunately, the five newsletters are necessary as this knowledge and scientific back-up are neglected in the public counseling of the population.

Take care of yourself and others,

A second wave of Corona epidemic is coming

Claus Hancke

That is why we need to be prepared

May 20, 2020

The Corona virus will return. Of course it will.

When and how bad it will be, we do not know, but it will come.

Curiously enough, most people expect the second wave this fall – what we are not being told is that this is because the population’s vitamin D level again will be low at that time that we also call the “flu season”.

One of Europe’s experts capabilities on Covid-19, Professor Christian Drosten of the Charité Institute at the University of Berlin, even thinks that the second wave could be tougher than the current one.

But should we then sit with our hands in our laps and wait for a vaccine?’
No, no and again no.

We must, of course, do everything we can to boost every Dane’s immune system so that we are “armed to the teeth” and can prevent a severe epidemic.

Well, isn’t it precisely an overreaction of the immune system (a cytokine storm) that kills lung patients? Yes. If they are vitamin-depleted, then it will happen.

However, several of the vitamins and minerals I have mentioned will specifically inhibit this cytokine storm from the activation of the NLRP3 inflammasome, which releases the inflammatory cytokines. Here, vitamin D and magnesium, selenium and the antioxidant vitamins are particularly important as they inhibit this cytokine storm and the subsequent inflammatory microcoagulation seen in the pulmonary vessels. It was described a week ago thoroughly in the Lancet by Prof. Dennis McGonagle and colleagues. They describe how there is actually inflammatory coagulation in the pulmonary vessels, rather than a pneumonia. Of course, this causes oxygen deficiency and such coagulation cannot be treated with a respirator. McGonagle and colleagues call it a diffuse alveolar and pulmonary interstitial inflammation in COVID-19 resulting in a macrophage activation that triggers extensive immunothrombosis.

Thus, according to this article, it is an inflammation-triggered immune response that leads to microcoagulation in the lungs, and that is what Covid-19 patients die from. This is interesting because this reaction can be dampened by vitamin D, selenium, magnesium and vitamin C.

Some of these substances have direct antiviral properties. We see this confirmed in the few scientific studies that are already published, as mentioned in the previous newsletters. The higher the level of intake (within a safe limit), the lower the mortality rate. Therefore, it is important to have high enough vitamin / mineral content for the immune system to be so effective that it will not cause severe lung disease. The more effectively we can prevent disease, the less we need treatment. The previous three newsletters have dealt with Vitamin D, Selenium and Zinc. Now we come to one of the cornerstones of human survival, namely Vitamin C. It is also called “ascorbic acid” after “a-scorbut”, ie against scurvy.

In the past, just as with other vitamins, these were believed to only protect against a deficiency of that vitamin. Thus, it was believed that vitamin C merely protected against scurvy, ie vitamin C deficiency.

However, the past 60-70 years of research have shown that vitamins (and certain minerals) have completely different and quite potent therapeutic properties when dosed accordingly.

Vitamin C is essential for our immune system, which has been documented in over 1,000 scientific articles. Finding evidence is not difficult. Rather, one must know how to limit oneself when searching.

Some of these articles are listed in the literature list. I have included a few old ones for historical reasons. After all, it is interesting that Frederick Klenner with high-dose vitamin C cured children from active polio, while here in Denmark we put them in iron lungs (the respirator of that time), while letting the virus rage in the body. Klenner killed the virus.

Another classic is Nobel Laureate Linus Pauling’s classic “The common cold …”, which created a great debate for and against.
Since that time, the scientific evidence has been well established and unanimously shows that vitamin C is essential for a well-functioning immune system.

Vitamin C has many extraordinary properties in that it can not only prevent disease but also be used in disease treatment.

If we are to concentrate on the current Covid-19 pandemic, then several serious studies around the world are using ascorbic acid intravenously to treat severe Covid-19 disease.

Contrary to the often heard mantra, “we have no treatment to offer Covid-19 patients”.

Well, we have.

It is true, however, that there are no gold standard randomized, double-blind, placebo-controlled studies published in reputable, peer-reviewed, medical journals. But come-on.

This is a completely harmless treatment with an extremely cheap, natural vitamin for a potentially fatal disease.

If the seriously ill Covid-19 patients have to wait for the above publication, then they will be dead. Why not try it when it can never hurt them? If doctors are nervous about the legal aspect, use Article 37 of the Helsinki Declaration on compassionate care. Here, the doctor’s judgment applies.

The theoretical basis for the antiviral effect of vitamin C is present, along with a second-to-none safety track record. There is even more than 70 years of clinical experience from doctors who have used ascorbic acid for a variety of diseases, including severe viral infections. In addition, a large number of scientific studies, which more than indicate that Vitamin C has a place in the treatment of viral infections.

The least that could be done was to do a pilot study with 10 patients hospitalized with severe Covid-19 disease and compare with 10 who did not receive vitamin C. All 20 patients would receive the standard treatment available today.
Then you can compare mortality, hospitalization time, and recovery time.
The study can be completed in a month within a general medical department’s budget. It can hardly be more simple.

But that is perhaps the problem.

The first four newsletters have dealt with optimization of the immune system using vitamin D, Selenium, Magnesium, Zinc and Vitamin C.

The next newsletter will summarize our knowledge of the Covid-19 pandemic and conclude with a comprehensive overview of what you can take if you want to be highly equipped with an optimally functioning immune system as the next virus threat approaches.

Severe Covid-19 disease can be prevented

Claus Hancke

But we don’t hear about it.

May 6, 2020

“Immunity! Well, that comes naturally.”
Does it?

Now we are so far into the corona crisis that the first serious scientific results are beginning to emerge, and since no one else does, the Vitality Council will try to disseminate these results.
“Just throw people into the water. They will swim by themselves ”.
A foolish claim. It is well known that the chances of surviving a dive into the water increases if you have learned to swim.
But that is, in fact, what the (Danish) authorities are saying, now that they are opening up the country while coronavirus is still circulating.
They are throwing people into increased viral exposure because then it is thought that people automatically get built-up immunity.
Well, this may be true if people can defend themselves, that is, have a well-functioning immune system.
Without good immune defence, people have no chance.

The (Danish) authorities  know very well that there are large groups in the population that have a impaired immune system. And yet, they expect us all to sit with our hands in our lap without doing anything while we wait for a vaccine that stands as an angel of salvation on the horizon.
A vaccine may be excellent, but firstly, it takes at least a year before we have it, and secondly, a vaccine can never keep up with a virus in the many mutations that make its immune profile so varied that a vaccine quickly becomes obsolete as we have seen with the flu vaccine.
The only thing that can keep up with an adequate immune response against a virus’ mutations is a well-functioning immune system in the individual.
Despite the knowledge that many people have an impaired immune system, we have in the months that the corona crisis has lasted, not once heard the (Danish) authorities give the public advice on how to optimize the immune system.
If the population has a fundamentally strong immune system, then a virus will do less harm as the individual course of disease will be milder.
People still get infected and maybe sick too, but they don’t have to die from it.

Let’s start with the simple, Vitamin D3.

It is quite evident that the Covid-19 disease is massively over-represented in the northern hemisphere. Just like the annual flu epidemic, which ravages the northern hemisphere in precisely December to March, whereas it ravages the southern hemisphere from August to October – and why is that?
We can thank the Sun for that. It is high in the sky in the summer and charges our stores of vitamin D, so we have a strong immune system from June to November, and of course the other way around in the southern hemisphere. We never get the flu in July-August.

A second indication is that elderly people are at particular risk. Older people more often have a very low level of vitamin D in their blood, as they do not get much out in the sun.

A third indication is that obesity is at particular risk. Vitamin D accumulates in the adipose tissue, where it does not benefit the immune system. Overweight people must therefore have a significantly higher dose of vitamin D to achieve the same blood concentration as slim persons.

A fourth indication is that the disease is over-represented in immigrants, who often have severe vitamin D deficiency. On the one hand, most immigrants have dark skin, which allows less passage of sunlight, and on the other hand, many immigrant women are covered, even in the summer, when they need to get their annual vitamin D dose.

A fifth indication is that diabetics are also a special risk group. On the one hand, diabetics often have an impaired immune system, and, on the other, many diabetics receive cholesterol-lowering medication. If people lack cholesterol, you cannot produce vitamin D, even though the sun is shining sufficiently.

A sixth indication is approaching evidence in the case of a recently published observational study that compared mean vitamin D levels in 20 European countries with prevalence and mortality caused by Covid-19. There was significant negative correlation between vitamin D level and both prevalence and mortality. It was interesting to see that both morbidity and mortality approached 0 in those populations where the vitamin D level was above 75 nmol/L.
Vitamin D levels are seriously low in the aging population, especially in Spain, Italy and Switzerland. This is also the most vulnerable group of the population in relation to Covid-19.

A healthy diet with green vegetables is also important, as they contain magnesium, which is a prerequisite for activating vitamin D.
Magnesium is included four places in the synthesis as well as the activation and deactivation of vitamin D, so without magnesium, vitamin D is ineffective.

If you combine these indices with solid evidence that vitamin D3 is essential for a functioning immune system, it is not far off to propose a solid dose of vitamin D3 to optimize a suffering immune system in immigrants, diabetics, older and overweight people in particular.

In the past, people were nervous about overdosing on Vitamin D, but this has proved unfounded. Extremely high doses need to be taken over a long period of time before there is any risk. In the past, it was also thought that a vitamin D level of 50 nmol/L was sufficient in the blood, but this is too low.
If people want to be sure that the vitamin D level is sufficient for an optimal immune system, the level should be between 75 – 150 nmol/L.

This newsletter is the first about some of the factors in our environment, nature, surroundings and diet that can optimize our immune system and thus reduce the risk of serious Covid-19 disease.
The next will deal with the latest research on selenium and Covid-19 disease.

Vitamin D protects against colon cancer

Claus Hancke

January 26, 2010

A huge European study now confirms that vitamin D may lower the risk of colon cancer by 40%.

The Danish Vitality Council has in several previous newsletters refered to scientific studies showing that vitamin D may lower the risk of cancer, and we have even been urged by journalists to withdraw those statements. Fortunately we have not complied.

A few days ago British Medical Journal published the largest study ever of the link between diet and health, known as the EPIC study, and this is just one of many results, we will see in the near future from this huge study.
More than half a million mostly healthy people from ten European countries have been closely studied and followed over 10 years by researchers from across Europe.

Participants completed detailed dietary questionnaires, and they have been checked with blood tests to identify their nutritional status.

At the time of analysis 1,250 cases of colon cancer had occurred and after comparison with a healthy control group researchers found that those who were low in vitamin D in their blood had significantly higher risk for this type of cancer.

Unlike many other studies this is characterized by being a prospective study. Thus looking-forward from the start time, and based on a group of healthy people. The study also distinguishes itself by involving so many different countries, cultures and – not least – food cultures.

Vitamin D, we primarily get from the sun, and a little bit from the diet. Danes are not the most tenacious fish eaters and much of the fish we eat is farmed and therefore does not include the fatty acids and other substances, we think they contain.

So we’re back at sunlight as the main natural source of vitamin D.

However, some of our ancestors for inscrutable reasons have found reason to settle north of the Alps, and it leads to midday sun high enough in the sky to make enough vitamin D in the skin for only 3-4 months a year (providing we have enough cholesterol).

So we must therefore tend to sunbathing when the Sun is at its highest point, ie the middle of the day, without sunblock, and therefore only half an hour, so we do not risk burning.

If it gets too complicated, you can also just grab a vitamin D capsule as a supplement. It is perhaps a little easier, and it can be done the whole year.
The dosage is somewhat controversial and should ideally be measured in a blood sample, but most serious scientists recommend between 2,000 and 4,000 IU, equivalent to 50-100 micrograms daily.

It will take a long time before we again will see such a thorough, multi-national study including so many people over such a long period.

So it is not just any study. It has high validity and ought to push the critically low RDA-value we have today.

Vitamin C slows cancer growth

Claus Hancke

August 13. 2008

More than 30 years of experience have shown the anti-cancer effect of vitamin C in both test tubes, animal tests and human trials.

Nevertheless, the Danish Cancer Society (Kræftens Bekæmpelse) does not consider it acceptable to apply yet.

Well-known effect on humans
As early as 1936, a young registrar at the Blegdam Hospital in Copenhagen published in the danish scientific journal “Ugeskrift for Læger” an experiment on two leukemia patients in which the disease improved on treatment with vitamin C (1). The young registrar was later to become the renowned professor of pediatrics, Preben Plum.

Forty years ago, researchers first found that vitamin C selectively kills cancer cells in tumors (2), and already 7 years later, Nobel laureate Linus Pauling and Scottish surgeon Ewan Cameron were able to publish a study in which they found an unprecedented survival time for cancer patients treated with vitamin C (3), and they could reproduce the results a few years later (4).

The Mayo Clinic in the USA quickly put a lid on the debate with a study on cancer patients with very small doses of vitamin C given as tablets, where, as you know, you can not consume very much until you get diarrhea; – the body’s natural “overflow valve”.

In 1982, Japanese researchers were able to reproduce Pauling and Cameron’s unusually long survival for cancer patients on Vitamin C (5).

Since then, numerous both animal and human trials have been published to treat cancer with vitamin C.

The new breakthrough
A few years ago, the National Institutes of Health (NIH) in the United States began to look at the old experiments extra carefully and found it relevant to retest them, and in 2006 they published a large-scale laboratory experiment that showed that when exposing cancer cells to vitamin C in the high doses that can be obtained by intravenous administration, it causes increased cell death in the cancer cells, that is without damaging the normal cells (6).

This prompted the NIH to move on, and last week we heard about their latest publication (7), where they had shown significant tumor size shrinkage in mice with implanted cancerous tumors treated with intravenous vitamin C.

The new skepticism
Now one would think that this news was received with enthusiasm and optimism in an organization like the Danish Cancer Society, whose main goal is probably best described in the name of the association; -but no.

We see in today’s newspaper BT that Anja Olsen from the Danish Cancer Society, who actually researches in diet and lifestyle’s significance for cancer, is absolutely not thrilled.

She tells BT: “It is ethically on the edge to treat with vitamin C. New treatments must be approved according to completely fixed rules, which means, among other things, that research must be carried out based on humans. “Until this is done, we do not know if it works, just as we can not rule out side effects,” she says.

Of course, it is easy for a researcher in the Danish Cancer Society to demand more research. That is what the Danish Cancer Society does. And how easy it is to spend more time on research when you have no illness yourself. But here “the film breaks off”.

The Danish Cancer Society (DCS) must wake up
For researchers far from patients and for administrators behind closed doors, of course, it is difficult to imagine; but as any general practitioner knows, the time factor for a cancer patient is of completely different dimensions than for the healthy.

The patient who has terminal supplements because “further treatment is hopeless” does not have a time frame of several years before it turns out whether a treatment works or not. He can not say “let’s wait and see”, because then he will never see.

He is looking for a way to prolong life and gain a little extra time. Shouldn’t he have that opportunity? And is it not better that he chooses a treatment which rests on evidence than anything else?

In addition, we have a treatment that has been free of side effects for 10-15 years of use, and a treatment that has numerous both animal experiments and human experiments as evidence.

Wake up DCS and stop moralizing. It can not be justified.

Denmark has a top position in cancer incidence and a bottom position in cancer treatment.

More clinics
A side-effect-free cancer treatment that selectively hits cancer cells without damaging normal cells at the same time is the ideal cancer treatment.

Once it seeps into the public health service and the Danish Cancer Society how good a palliative and life-prolonging treatment Vitamin C can be, then we must hope that large outpatient clinics will be established so that this treatment in the future can be offered for free to cancer patients in Denmark.

Vitamin D against atherosclerosis

Claus Hancke

January 28, 2008

Vitamin D counteracts the development of atherosclerosis and prevents fatal complications of high blood pressure – but vitamin D deficiency is very widespread.

We are not done with vitamin D. More and more information is streaming in about this amazing substance, which is actually not a vitamin but a hormone created in skin exposed to sunlight.

Now we will look at vitamin D’s effects on the heart and circulation. It seems as though the risks of blood clots in the heart and the brain are far lower in people who get enough vitamin D, which is to say people who get more than most. This “vitamin” is especially effective at lowering the risk in people with high blood pressure.

This find appears in a recent report from Farmingham, a little town in Massachusetts where the health and lifestyles of thousands of people (and their descendents) has been registered since 1948 in order to find lifestyle related reasons for cardiovascular disease. The Farmingham study is, without a doubt, the most famous of its kind. When we today take for granted that exercise, healthy diet, and aspirin prevents cardiac death it is the Farmingham project that we should thank.

The report in question is on a part of the study involving 1,739 people aged 50 – 70 who were free of cardiovascular disease at the beginning of the study. From 1996 to 2000 their vitamin D status was measured with blood tests after which their health was monitored for an average of 5.4 years (up to 7.6 years). Who suffered blood clots?

Those who had the least vitamin D in the blood! After seven years blood clots in the heart or the brain (stroke) was registered in one in ten with vitamin D levels over 37 nmol/l, but in no less than one in four of those with levels under 37. After correcting for differences within the group such as age, sex, cholesterol levels, smoking, diabetes, and so on, the group with the highest vitamin D levels still had a cardiovascular risk 60 % less than that of the group with the lowest levels. If these numbers are right, vitamin D is more important for cardiovascular health than aspirin or cholesterol medicine.

Strong immune system
The beneficial effects of vitamin D seem to be even greater for those with high blood pressure, which is the most important cause of cardiovascular disease. Among participants with high blood pressure the risk for those with vitamin D levels over 37 was half that of those with levels under 37.

This result is similar to that of other studies which have shown that low vitamin D status and high blood pressure and clogged cardiac arteries are related. The Farmingham has an even stronger message: If you lack vitamin D you are at risk of a heart attack within the foreseeable future.

Does this mean that vitamin D prevents atherosclerosis? Yes, this seems to be the case. This fits in well with other known effects including: that vitamin D counteracts an important hormone (renin) which is responsible for raising blood pressure and that when heart cells which normally use vitamin D are prevented from using vitamin D (through genetic manipulation) in experiments on mice, blood pressure rises quickly.

Without eating fatty fish is you get almost no vitamin D from October to May. Deficiency is therefore very widespread. In a European study of teenage girls more than one out of every three had severe anemia (blood percent of under 25 nmol/l). Over 90% of these girls would have, if they lived in Farmingham, ended up in the study group with severe atherosclerosis.

How much vitamin D is it wise to take? There is no rule of thumb, but it should be considered that a typical vitamin pill contains 200 units whereas one out of every two adult Americans need 1,000 units in order to have an “acceptable” vitamin D status (which is a concentration of 75 nmol/l – most American researchers recommend 75 – 150 nmol/l). It is also understood that it is completely safe to take up to 2,000 units daily.

Luz Tavera-Mendoza and John White, two molecular biologists from the American McGill University have shown that vitamin D causes the skin and the immune system to form antibiotics (cathelicidin and more) which kill bacteria, including tuberculosis bacteria. This is probably the explanation for the earlier idea that it is possible to cure tuberculosis with sunlight. These two researchers have written an easy to read summery of recent research and even reveal what they take as supplements during the dark months.

Luz, who is a younger woman, takes 1,000 unites (25 micrograms).
John, who is a younger man, takes 4,000 units (100 micrograms).
