Why Supplement Vitamin D? Immune Protection!

I am not a doctor. So, when I saw this video by clinical pathologist Dr. Ryan Cole, I listened. His concise straight talk from direct medical experience cuts through so much confusion. Turns out LOW VITAMIN D LEVEL is a MAJOR RISK in viral infection and hospitalization. Vitamin D protects immunity, and we’re all low in it. I summarized his talk below. Find the whole lecture here.

Dr. Ryan Cole runs Cole Diagnostics, one of the largest independent laboratories in Idaho, started 17 years ago. He is a Mayo Clinic trained board-certified pathologist, board-certified in anatomic and clinical pathology, with expertise in immunology and virology. He has a sub-specialty in skin pathology and does a lot of skin cancer diagnostics. He has seen about 350,000 patients in his career and has done about a hundred thousand Covid tests in the past year. Doctor Cole suggests that public health messages are missing valid treatments which should be available to everybody.

The Pandemic Has Run its Course
Now statistically the pandemic is over in Idaho. Once we’re statistically below a set percentage we’re not in a pandemic, we’re endemic. We’re still doing maybe 500 to 600 patient tests a day, and at most we’re seeing 2% per day positive right now, so the numbers are going way down.

Coronaviruses are seasonal. They follow a six-to-nine-month life cycle. No matter what we do, they’re going to do what they do, and after their season they’re going to fade. The average Covid-19 death age is 78.6. Compare that to the average age of death in north America every year is also 78.6. The same. That is fascinating.

Three Highest Risk Factors

What are our three highest risk factors? Clearly, they are:

  1. Obesity
  2. Low Vitamin D levels
  3. Advanced age

But the virus is fragile. The’re just little tidbits. It’s fragile and doesn’t survive outside. UV light from the sun fractionates it, kills it, blows it apart. Ventilation in the wind blows it away. That is why it is insanity to wear a mask outside.

The biggest lost message on this entire pandemic is Vitamin D. If I can give one message to all of you for every winter and autumn for the rest of your lives it is this:

“There’s no such thing as flu & cold season. There is only low Vitamin D season.”

Every cell in your body has a nucleus, and every nucleus has a receptor for Vitamin D on it. Two thousand genes in your body are controlled by Vitamin D. Five percent of your body’s genome is controlled by Vitamin D. It is the master key to your immune system, the master key. If one has a Vitamin D level in mid-range, you cannot develop a cytokine storm. Dis the cytokine storm. If you are in mid-level range of Vitamin D, you will not die from Covid because you cannot get a cytokine storm.

It’s a Vitamin D Deficiency Pandemic
We have an international Vitamin D deficiency pandemic. 70 % of the world is immune suppressed. 70 – 80 % of all Americans are immune suppressed because they are D deficient. 82 to 88 % of nursing home patients are deficient. Who is dying at the highest rate? Nursing home patients. 83 % of African Americans, 70 % of Latinos, 72 % of native Americans, 47 % of Caucasians are insufficient and 80 % of all hospitalized patients statistically are Vitamin D deficient. 96 % of people in the hospital ICU are Vitamin D deficient. If you are D deficient you are immune suppressed, you are susceptible to the common cold, the flu, coronavirus, or any sort of bacterial pneumonia. So, the best mask of all is a healthy immune system.

We synthesize Vitamin D through our skin above the 35th parallel in the world.  The older you get, the harder it becomes to synthesize it. Vitamin D is critical to all people living in the Northern 2/3 of the USA. If you do not supplement your Vitamin D levels, you are immune suppressed in the fall in the winter.

Here are maps of the 35th parallel. If you live at or below the 35th parallel for four to five months of the year, you cannot synthesize Vitamin D through your skin. That means most of the USA, all of Europe, most of Australia. You have to supplement. Many doctors recommend 4,000 IU per day.

Scandinavians test their citizens twice a year.
They supplement 35 % of their foods on their food shelves with Vitamin D. So, why are Finland, Norway, Sweden doing so well? They take care of the public health of their people.

We’re Also Deficient in Magnesium and Zinc
80 % of Americans also are magnesium deficient. Our soils are depleted. Vitamin D and magnesium play a fine dance, so you need them both to work together in order to have a functional immune system. We’re also zinc deficient, including 70 to 80 % of us in this room. Diet, diet, diet, diet. What you eat matters. It affects your immune health. Obesity drastically reduces your ability to get Vitamin D into your circulation. That’s because D is a fat-soluble vitamin. The heavier you are the more it goes into your fat and not into your circulation to stimulate your immune system.

Why Do You Need to Supplement Vitamin D?
Normal D levels also decrease risk of colon cancer, breast cancer, thyroid cancer, depression rates, and suicide rates. Eight out of the ten highest suicide states are northern tiered states, simply because of Vitamin D deficiency.

Vitamin D is not a vitamin. It’s a prohormone. (Prohormones are substances that the body converts to a hormone. In fact, only about 10 % of the vitamin D the body needs comes from food like dairy and oily fish. The rest the body makes for itself.) Vitamin D affects thousands of genes in your body. When you get a D level up to normal, you decrease risk for all of these things, not just Covid. It is an essential prohormone that your body naturally makes in the sunshine from spring through summer only a couple hours a day. There’s only about a three-hour window a day without your sunscreen (don’t tell the dermatologist). You need to be outside for 20 to 30 minutes during the spring and summer to get natural Vitamin D. In the fall in winter, you need to supplement to boost your immune system.

Why are Blacks and Latinos in Northern Areas More at Risk?
The darker your skin and the further north you live, the harder it is to synthesize Vitamin D. That’s why the hospitalization and the death rates in the darker skinned populations is higher. It’s not social disparity in this case – it is plain and simple biology. The darker your skin and the further north you live, the lower your Vitamin D level and the higher your risk for Covid and all other diseases will be.

Eat Healthy
Of course, it is key to cut out the sugar. Cut out the processed foods. Cut out the carbohydrates. Those are all inflammatory. The more inflamed you are when going into an illness, the worse you will do. So, obesity is a predisposed inflammatory state. If you are obese, you are inflamed.

Natural Medications
Ivermectin, if added to the mix of treatments, decreases the death rate by 75 %. If given early, by 86 %. What does that mean? Of the half-million deaths we have in North America we would have had 375,000 fewer deaths. There is blood on the hands of bureaucrats in Washington who have suppressed this life-saving medication. Blood on the hands of those individuals. How much does it cost? How many people got Covid that were not on Ivermectin? Scandinavian studies showed that it prevented acquisition by 88 multiple mechanisms of action of this molecule. I don’t have time for a long medical lecture, but it’s fun to know the beauty of it.

Natural Treatments Cover All Virus Variants
This treatment can cover all the variants because of its mechanisms. Unlike “Oh, we’re going to have to give you a new formulation of this vaccine or that vaccine.” No, the mechanisms of the action of this molecule against this virus don’t stop there. There’s a great website by FLCCC doctors that are front line pushing this forward. They’re the ones that got the NIH to finally listen, to finally take a neutral stance to unshackle the hands of physicians that can prescribe it.

“In October 2020, the FLCCC Alliance identified, based on a review of the recent and rapidly emerging clinical trials evidence, that ivermectin, an anti-parasitic medicine, has highly potent real-world, anti-viral, and anti-inflammatory properties against SARS-CoV-2 and COVID-19.” https://covid19criticalcare.com/about/the-flccc-physicians/

I can say that I’ve saved 42 lives in the last two months with this protocol. I don’t prescribe very often, you know, I’m generally behind the microscope or in the lab. But I know from one case to another.

This is NOT a Vaccine
By definition a vaccine historically is giving a protein or an antigen or a part of a pathogen and / or a whole killed pathogen, injecting a sequence of its mRNA into a human being, and this is a medical device historically. But what we’re doing right now does not fall under the definition of a Vaccine. They shifted the verbiage in some of the federal register back in October, so they could approve this. So, it was a sleight of hand to change the verbiage. What we have right now is an experimental biological gene therapy immune modulatory injection. We are injecting people with a synthetic sequence of nucleic acid. We have never done this on a large scale in human history. mRNA trials in mammals have led to odd cancers. mRNA trials on mammals have led to autoimmune diseases. Not right away, but six nine twelve months later. So, a quick question then. So, the lipid nanoparticles that are actually in the vaccines can actually cause the cytokine storm. Lipid nanoparticles are the question. The lipid nanoparticles in these shots 70 % of us are allergic to. Polyethylene glycol that is antifreeze, Polyethylene glycol 2000 if you get a coronavirus shot.

Animal Trials of “Vaccines” Unsuccessful
Historically with SARS MERS animal coronaviruses, if you get a shot, then when you’re exposed to a wild type of variant of the virus 6 9 12 months later, the immune system can go haywire. In the SARS vaccine trials on ferrets and the monkeys, 100 % of the animals when exposed to wild-type virus ended up with immune reaction.

OK, How Much Vitamin D Do I Need?

These doctors recommend Vitamin D supplementation of 4000 IU.  

Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes. The scientific evidence shows:

  • Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
  • Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
  • Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment.
  • Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
  • Causal inference modelling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.
  • The US NAM said 4000 IU “is likely to pose no risk of adverse health effects to most individuals.”

Evidence to date suggests the possibility that the COVID-19 pandemic sustains itself in large part through infection of those with low vitamin D, and that deaths are concentrated largely in those with deficiency. The mere possibility that this is so should compel urgent gathering of more vitamin D data. Even without more data, the preponderance of evidence indicates that increased vitamin D would help reduce infections, hospitalizations, ICU admissions, & deaths.

Decades of safety data show that vitamin D has very low risk: Toxicity would be extremely rare with the recommendations here. The risk of insufficient levels far outweighs any risk from levels that seem to provide most of the protection against COVID-19, and this is notably different from drugs. Vitamin D is much safer than steroids, such as dexamethasone, the most widely accepted treatment to have also demonstrated a large COVID-19 benefit. Vitamin D’s safety is more like that of face masks. There is no need to wait for further clinical trials to increase use of something so safe, especially when remedying high rates of deficiency/insufficiency should already be a priority.

Many factors are known to predispose individuals to higher risk from exposure to SARS-CoV-2, such as age, being male, comorbidities, etc., but inadequate vitamin D is by far the most easily and quickly modifiable risk factor with abundant evidence to support a large effect. Vitamin D is inexpensive and has negligible risk compared to the considerable risk of COVID-19.

Hello, and thanks for reading to the end. We are in Bali right now, enjoying the intense sunlight. Today I’m at the black sand beaches near our home at Keramas Sacred River Village on the Southeast coast. The pandemic is not a problem here. I do not take a Vitamin D supplement at the moment. Yes, I get lots of sun, both direct and indirect. And I avoid sunburn. Come for a visit!
