Neglected opportunities

Claus Hancke

January 15, 2021

“The world is groping blindly for defences against the new virus variants” – according to a headline in the Danish newspaper Berlingske January 12th. The article then deals with gene sequencing and rapid diagnostics for infection control. But it is clear that panic spreads every time a new variant appears.

The fumbling in the dark began with clusters 1-5 found in Danish mink, which led to politician panic and the most drastic coercive intervention so far against any business in Denmark and the total closure of the region Vendsyssel.

The next time the panic screw was increased is now that the English variant B 1.1.7 is spreading. It is not more dangerous, but more contagious.

When the panic and anxiety from this variant begin to subside, then it’s time to introduce the South African variant and gravely tell us that this variant can now hit children, and then shut the country down. It is so deeply predictable that we absolutely must be pressed down into a state of chronic anxiety so that we conform to what is expected, and all of us line up for vaccination.

However, it is a good thing that the vaccines have arrived. The first vaccine was received by the media and politicians like a Messiah, and it was very nearly close to rose petals being sprinkled on the road in front of the trucks.

It is excellent that the health authorities quickly have launched vaccinating the elderly and seriously ill at risk. So far so good.

But my goodness, how they could have done so much good in the 10 months that have passed if they had listened to science.

When you consider that in order to shop in the supermarket Netto you have to look like a bank robber and wear a face mask whose effect is extremely poorly documented; -then it is striking that for months the authorities have turned a blind eye to well-documented opportunities that could have saved many lives and much suffering.

A study recently published in the Lancet (1) reviewed 89,000 hospitalizations with Covid-19 in March-April 2020 and Influenza Dec-Jan 2017-18.

It was found that Covid-19 caused significantly longer length of stay and greater mortality than the flu and it was concluded that in the future every effort should be made to prevent and vaccinate as well as find methods for treating Covid-19.

The Vital Council can only agree on this 3-string strategy: prevent, vaccinate, find ways to treat.

Unfortunately, this is not the strategy the government has chosen. Instead, they have chosen to put all their eggs in one basket.
Ever since the start of the pandemic, there has been hope and talk about the upcoming vaccine.
The authorities have been going all in, bone-hard, on the vaccine and only the vaccine and have not even wanted to squint at the other options in the three-stringed strategy mentioned above.

You can therefore understand the panic of the politicians until they were reassured that the mink variant was probably also sensitive to the upcoming vaccine. The same has now happened with B 1.1.7 from England, while we are still unsure of the South African variant.
That is to say the vaccines may in the future have difficulty keeping up with the constant changes in the highly mutated RNA virus, and one day they will fall short.

Yet all measures other than vaccines have been swept off the table despite massive documentation.
It is as if the authorities have overlooked that we humans actually have an immune system that is itself capable of adapting a new virus mutant.
Unlike a vaccine, a well-functioning immune system will be able to keep up every time a virus mutates.

Of course, it is necessary for the immune system to function optimally, and it ris necessary that we humans get a diet with the nutrients that the immune system needs.

This is so obvious that it hurts to say over and over again (see 5 previous newsletters from May 2020):
Decades of scientific evidence show that deficiency of especially vitamins A, C, D and K as well as deficiency of selenium, magnesium and zinc weakens the immune response and increases the incidence of infections, especially lung diseases. (2-10)

Specifically, in recent years there has been extensive writing about vitamin D, and the University of Copenhagen wrote almost prophetically on March 7, 2020, on its website in the News section: “Vitamin D is absolutely crucial for the immune system.”

Since then, several studies have been performed on vitamin D against Covid-19, which show significantly less infectivity, shorter hospital stays, milder illness, and lower mortality. (11-17) This documentation is further strengthened by the fact that the groups that are low in Vitamin D are those most affected by Covid-19, especially overweight persons, nursing home residents, immigrants, the chronically ill, and the elderly.

Traditionally, here in Denmark we have considered it sufficient, as long as the serum vitamin D (25-hydroxyvitamin D) level was 50 nmol/L (20 ng/ml) or more. This is not enough. All studies point to the need to have at least 75 nmol/L (30 ng/ml) in the blood and preferably 150 nmol/L (60 ng/ml.)
Far less than half of the Danish population are within these figures.
You cannot reach this preferred level, even if you then eat fatty fish every single day; you have to take supplements.
In turn, there is a major health benefit in eliminating the population’s deficiency of vitamin D. -Not only in the face of several of the major lifestyle diseases, but also of Covid-19.

Research shows, as mentioned, that sufficient vitamin D will shorten the duration of the disease, avoid hospitalizations, and reduce mortality from covid-19 disease. Those who become ill will simply have a mild course of the disease but will still build up immunological defenses until the next time they encounter it. If you also make sure that there is no shortage of the other above-mentioned vitamins and minerals, then the disease picture will look completely different in this country, and it could put a damper on the all-consuming anxiety and worry in the population.

Note: There is no talk of these vitamins and minerals being used to “treat” anything. They are used to correct deficiencies.

But it requires the authorities to think outside the box and show openness to the well-documented possibilities that exist here. Especially when these options are safe.
It is fine to think of collective infection control, but it does not preclude that one also thinks of the individual’s immune system and its well-being.

There has been an unfortunate streak of overlooked possibilities throughout the 10-month-long corona course. Opportunities that could have saved many lives and saved many sufferings.
-And these are, mind you, options that are significantly better documented than face masks.

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.

Zinc is important for the immune system

Claus Hancke

– also for Covid-19 disease

May 18 2020

In continuation of the previous two newsletters on Vitamin D and Selenium, a little important information about Zinc and its importance to the immune system is now presented here.

In these corona times, it is especially necessary that we each optimize our immune system so that we are well prepared for a possible new wave in about half a year from now, when people’s deposits of vitamin D again are declining.

In the Western part of the world, about 25% of the population has some level of zinc deficiency, especially the elderly, people with high alcohol consumption, people with chronic infections, those who get certain types of medicine, and elite athletes, who use up their magnesium and zinc.

Zinc is part of more than 200 different enzyme systems and is a prerequisite for normal growth and cell formation and a well-functioning immune system.

There is solid evidence that zinc deficiency leads to increased susceptibility to infection. Since zinc supplementation has also been found to reduce the duration of a cold, various zinc lozenges have been tried, and a Cochrane study of 18 studies found that 75 mg of zinc a day could reduce the duration of cold symptoms in healthy people, provided the zinc tablets were given within the first 24 hours after symptom onset.

The effect lies, among other things, in the skin and mucous membranes, where zinc is necessary for the cell replication that the body initiates when an infection is to be fought. This is especially true regarding the growth, maturation and differentiation of circulating lymphocytes, T cells and the killer cells, NK cells that we need to fight viruses.

In 2010, an in vitro study showed that zinc inhibits another coronavirus, namely SARS-CoV, which caused an epidemic in 2002. Zinc has a direct antiviral effect by inhibiting SARS-CoV RNA polymerase, which is a prerequisite for virus replication.

There is no specific study yet on the effect of zinc on the current CoV-Sars-2, but natural connections are looked for and, for example, the current Covid-19 disease is characterized by many people’s losing the sense of taste and smell, which is also seen in the case of zinc deficiency.
But it could be coincidence.

We have to take zinc all the time, as it is not stored specifically. It is not difficult to get enough zinc here in Denmark, just by eating real food and not industrial synthetic ‘plastic’ food. Zinc is found in meat, seafood, organ meat, fish, eggs, legumes, cereals, dairy products, green vegetables, fruits and berries. An intake of 20-30 mg per day is enough.

If you take zinc as a supplement, remember that it can reduce the copper content of the body, as zinc will upregulate the metallothionein synthesis, which can cause copper loss. This is probably not of great importance here in Denmark, where a large pig production has given us all a solid copper supplement.

In any case, we need zinc to optimize our immune system, so we are ready to fight an virus infection.

Now you have read about vitamin D, selenium and zinc in relation to the immune system.
The next newsletter to arm your immune system against Covid-19 will be about Vitamin C.

Selenium attenuates Covid-19 disease

Claus Hancke

But we don’t hear about it

May 11, 2020

At this time, new research is emerging, newly published, especially about SARS-CoV-2, which has shut down the world with its follow-up Covid-19. This disease specifically affects the lungs, which is why people with lung disease are at special risk of serious illness.

One of the world’s most respected selenium researchers, Margaret Rayman, together with a team of researchers, has just published an important letter in the American Journal for Clinical Nutrition that shows a significantly (P <0.0001) higher cure rate for Covid-19 patients with higher selenium levels in the body.

An interesting study from 2004 (Beck) showed that if a virus like corona passes through a host animal with selenium deficiency, the viral virulence will increase. The host animal lacks selenium to produce glutathione peroxidase for its own protection, thus allowing the virus to mutate freely to a more virulent form. Such selenium-deficient host animals are found in large selenium-poor areas of China, and could, for example, be a bat, or more likely a civet, which is a Chinese cat-like animal resembling a mongoose a little bit. It is eminent for adapting to urban environments and can be a nuisance near human housing where the cats’ excrements make a mess and carry diseases – especially if the animals lack selenium.

Rayman mentions a number of diseases that are improved by optimizing selenium supplementation via the immunomodulatory effect of selenium, in particular selenium’s ability to attenuate the virus’s ability to mutate in a more virulent direction.

Along with the above zoological observation, this led Rayman and colleagues to assume that selenium status and Covid-19 disease had a relationship, and they wanted to find it.

In a retrospective population-based analysis, daily reports (from a credible, non-governmental source) were collected from each province, municipality and city on confirmed cases, cured and deceased Covid-19 patients.

From previous studies, data on selenium levels in individual small districts were reported as selenium concentration in hair. Hair selenium concentrations have shown strong correlation with selenium intake in the different Chinese districts.

By the term “cured” is meant more than three days of fever-free lung function and lung symptoms clearly improved pulmonary x-ray or scan normal, and negative immunological test for the lung pathogen in question in two subsequent tests at least one day apart.

The recovery was significantly lower in Hubei Province (13.2%) compared to all other provinces (40.6%), and mortality in Hubei Province higher (3% – sick) than in all other provinces (0.6 %). Both differences are highly significant (P <0.0001).

However, one of the cities of Hubei Province showed remarkably higher recovery rates than the rest of the cities of Hubei, and it was Enshi (36.4%), which is known for high selenium intake and high selenium status.
The reason China is so thoroughly researched for selenium, is because there are areas in China with both the world’s lowest – and the world’s highest occurrences of selenium in the soil and in the food.

An area of very low selenium status is Keshan in northeastern Heilongjiang Province. We know Keshan disease, which is a cardiomyopathy / heart failure due to selenium deficiency. In Keshan, the mortality rate was 2.4% compared to the other province’s 0.5%.

The Rayman study has significant weaknesses in confounding factors and the use of old selenium data. It was also published as a “facilitator” so that the news can come out as quickly as possible at a time when any whistleblow is welcome and every stone must be turned over.
The Vitality Council has emphasized that the research does come from a serious researcher, Margaret Rayman.

Furthermore, when we can link her new data with a large number of heavy scientific studies, all of which point to selenium as a key ingredient in our immune system, the Vitality Council will conclude that selenium is necessary to optimize our immune system, so we won’t get so sick from Covid-19.

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.
