Study finds Vitamin D’s Ability to fend off COVID

Natural News dated 4 May 2022 published this information on Vitamin D “Israeli study provides strong new evidence that vitamin D has unique ability to fend off COVID-19


A newly published study by Israeli scientists confirms — again — that there are natural ways to fight back against COVID-19 without resorting to harmful and useless vaccines.


According to peer-reviewed research published in the journal PLOS One last week, Israeli scientists said they have found the most compelling and convincing evidence to date that boosting vitamin D levels helps people who have contracted the virus dramatically reduce the risk of serious illness or death, The Times of Israel reports.

Lack of Vitamin D3 could lead to one or more of 100 diseases

NaturalHealth 365 dated 1 October 2019 published this Vitamin D Information “Lack of vitamin D connected to premature death, study says”.   For example, Harvard T.H. Chan School of Public Health states that ‘vitamin D deficiency is a global concern.’  But, it’s not just Harvard, many researchers have reported that optimal vitamin D3 levels effectively assists in preventing premature death by any cause.  For example, most recently, the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Barcelona, Spain revealed that “vitamin D deficiency is strongly linked to increased mortality, especially in younger and middle-aged people.”  

[Marilyn comment]  I have been taking nutritional supplements since June 1996 and today – 21 July 2020 – have no health issues.   I source my products through network marketing companies.  I keep alerting my teams to the fact that products containing Vitamin D are vitally important to all of our health.  


For many years the Cancer authorities have pushed the mantra – slip, slap, slop.   This campaign has left a world full of people with a Vitamin D deficiency.

The importance of Vitamin D

NaturalNews on 6 September 2019 published this information on vitamin D7 Reasons why you should always get enough of vitamin D”. 

Vitamin D is a unique kind of vitamin that does not act in the same way that other vitamins do. Instead, it acts more like a hormone that is naturally produced by your body. It is known as the “Sunshine Vitamin” because you normally get this vitamin from your skin’s exposure to sunlight.

The way it works is that the sun beams down strong ultraviolet B (UVB) rays when it shines during the day. When these rays interact with the cholesterol in your skin cells, this provides the energy for vitamin D synthesis to occur. If you happen to live in an area that is far from the equator, or if you spend a lot of your time indoors, you might not get enough vitamin D. If you aren’t careful, this could potentially put you at risk of vitamin D deficiency, which can be a cause for concern because vitamin D is essential for optimal health. (Related: The Amazing Health Benefits of Vitamin D.)

Vitamin D Deficiency as cause for disease

Dr Marc Sircus dated 2 August 2019 published this information on Vitamin D articleVitamin D Deficiency as a Cause of Diseases & Safe High Dose Vitamin D Treatments.  

Mayo Clinic: "Vitamin D toxicity is rare in people who take supplements, researchers report." The evidence is clear that vitamin D toxicity is one of the rarest medical conditions and is typically due to intentional or inadvertent intake of extremely high doses," writes Dr. Hollick, a professor of medicine, physiology and biophysics at Boston University School of Medicine.


Oncologists and much of the rest of the western medical establishment actually thrives on the epidemic of cancer and nowhere can that be seen more clearly than its attitude toward the sun and its preference for the super high toxicity of chemo and radiation therapy as opposed to the low toxicity of vitamin D, iodine and even selenium (when it is administered in the right form). 

One study on vitamin D used as high as 540,000 units for severe lung disease.[1] High dose vitamin D administration in ventilated intensive care unit patients has also been studied using 50,000IU vitamin D3 or 100,000IU vitamin D3 daily for 5 consecutive days (total vitamin D3 dose=250,000IU or 500,000IU, respectively) without an cause for alarm.[2] 


One company in the USA makes tablets that are 50,000 and recommended as high as four a day (200,000 units for four days) for at risk patients. Now because of the FDA oppression they will not make such recommendations.

Unwanted belly fat

NaturalHealth365 dated 10 November 2018 published this information on vitamin D article “Research shows that low vitamin D levels are linked to unwanted belly fat  Here is an excerpt:


“You are probably aware that vitamin D deficiency is bad news for bone health, and additionally expose you to risks such as obesity, cancer, diabetes and cardiovascular disease.  But, what you might not know is that the bigger your belly is, the higher the chances that you have low vitamin D levels.

These new findings were presented in Barcelona during the European Society of Endocrinology annual meeting.   So, the word is getting out.  We just have to encourage doctors to study the medical literature.”

Do you suffer from IBS – Good news contained herein

NaturalHealth 365 dated 12 April 2018 published this article “Vitamin D deficiency linked to more painful digestive health problems.”  An excerpt from the article:


Vitamin D is integral to immune system health, bone health, brain functioning and fighting cancer. Now new research out of the University of Sheffield Department of Oncology and Metabolism has found that optimal vitamin D levels can help to ease painful IBS (Irritable Bowel Syndrome) symptoms as well.


IBS (sometimes called IBD – Irritable Bowel Disease) is a painful condition that affects about 3 million people in the United States and two out of every 10 people in the UK. It is a functional disorder of the GI (gastrointestinal) tract, and in some cases can be quite debilitating.  Yet, we know there are many natural ways to eliminate digestive health problems.


It should be noted that IBS tends to be the catalyst for around 10 percent of all GP surgical clinic visits. Plus, this avoidable health problem causes many to miss work and greatly lower overall quality of life.”


This information on vitamin d article also advises “Vitamin D levels of around 40 ng/mL ideal for supporting optimal health”.     Please make sure you read the full article.

Top articles on Vitamin D

Top Twelve Vitamin D Papers for 2017”.  The article goes on to say:


“While the importance of vitamin D for calcium absorption and metabolism and bone health was recognized about a century ago, its importance for non-skeletal effects has only been generally recognized and appreciated in this century. Most of the supporting evidence is either from observational studies related to serum 25-hydroxyvitamin D [25(OH)D] concentrations, including prospective studies, or studies of vitamin D mechanisms, with some of the evidence coming from clinical trials. Indirect support comes from the fact that skin pigmentation varies globally in response to prevailing solar ultraviolet-B (UVB) doses as modified by clouds and forest cover, and that nearly every cell in the body has vitamin D receptors. Most of the effects of vitamin D are mediated through the hormonal metabolite of vitamin D, 1,25-dihydroxyvitamin D, binding to a vitamin D receptor and affecting gene expression, upregulating some, downregulating others; the production of this metabolite in target tissues being regulated mainly through the availability of 25(OH)D in the circulation and by local production of the catabolic 24(OH)ase enzyme [Ganguly, 2017]. However, in order for the health systems to recommend higher serum 25(OH)D concentrations appropriate for non-skeletal effects, clinical trials are required. The year 2017 saw some progress along this front.”

Vitamin D and Infertility

NaturalNews dated 26 December 2017 published this information on vitamin d article: “Vitamin D fights disease and infertility: New study finds women with PCOS have a higher success rate with vitamin D”.    The information on Vitamin D article goes on to say:


“Trying to conceive might sound exciting on the surface, but it can quickly turn into a source of frustration for women who suffer from polycystic ovary syndrome, or PCOS. This hormonal disorder, which affects five to 10 percent of women who are at the age of reproduction, often causes infertility because of a lack of ovulation, among other effects. Many of these women end up seeking fertility treatment to help improve their chances.”

Vitamin D’s role in lowering cancer risk

Dr Mercola on 10 April 2017 published an article entitled “Higher Vitamin D Levels Lower Cancer Risk”.   His story at a glance:


  • “Vitamin D is involved in the biology of all cells in your body, including your immune cells. A large number of studies have shown raising your vitamin D level can significantly reduce your risk of cancer
  • Most recently, researchers found vitamin D and calcium supplementation lowered participants’ overall cancer risk by 30 percent
  • Having a serum vitamin D level of at least 40 ng/mL reduces your risk for cancer by 67 percent compared to having a level of 20 ng/ml or less; most cancers occur in people with a vitamin D level between 10 and 40 ng/mL

Researchers at the Queen Mary University of London found that vitamin D supplementation keep respiratory diseases such as cough and colds at bay. Data show that vitamin D supplementation resulted in a 12 percent reduction in the proportion of patients suffering at least one acute respiratory tract infection. Researchers also noted that vitamin D supplementation helped keep respiratory infections in check, especially among vitamin deficient individuals. To asses this the scientists examined more than 11,000 patients who participated in 25 clinical trials across 14 countries, including the U.K., India, Afghanistan, and Japan as well Belgium, Italy, Australia, Canada and the U.S.”

NaturalHealth365 on 22 February 2015 brings more information on Vitamin D and on how low doses of this vitamin in your system cause higher mortality rates.  The article goes on to say:


“Last June, in the Journal of Public Health, after analyzing 32 vitamin D studies over a 40 year period of time, researchers suggested that risk of premature death from any cause was significantly higher when vitamin D levels fell below 30 mg/nl.


Now, another 13-year prospective study conducted by the American Journal of Clinical Nutrition confirms these findings. This study’s perspective highlighted premature death from cardiovascular disease, cancers, fracture and respiratory disease with chronically low vitamin D levels.”

  • Needed just to maintain your levels – 4,000 IU/day
  • Latitude above/below which the body cannot make vitamin D levels during winter – 52nd Parallel
  • Mothers who took 4,000 IU during pregnancy had their risk of premature birt reduced by half.
  • Numerous studies show that optimising serum levels protects again 17 varieties of cancer, as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteo and rheumatoid arthritis, Alzheimer’s disease, periodontal disease etc.

Vitamin D2, D3 and D4

GreenMedia on 7 August 2015 brings a great deal of information on Vitamin D and the humble mushroom with regards to its vitamin D content.   It is very interesting reading and I was delighted to learn that the Shitake Mushroom not only produce vitamin D2 but also produce vitamin D3 and vitamin D4.  WOW!    Click this link to read the article.


I recently started to make a Shitake and Chicken Mushroom soup and have this most days with a Cruskit spread with Avocado.


Chicken, Shiitake and Bok Choy Soup - 6 serves

  • 8 cups canned low-salt chicken broth
  • 6 ounces fresh shiitake mushrooms (about 10 large), stemmed, caps sliced
  • 2 tablespoons minced peeled fresh ginger
  • 3 tablespoons fish sauce
  • 1 tablespoon soy sauce
  • 1 tablespoon oriental sesame oil*
  • 1/4 teaspoon chili oil*
  • 3 cups thinly sliced bok choy
  • 4 teaspoons rice vinegar*
  • 2 green onions, sliced


Bring broth, mushrooms and ginger to boil in large pot. Reduce heat and simmer 3 minutes. Add fish sauce, soy sauce, sesame oil and chilli oil and simmer 2 minutes. Add bok choy and simmer until bok choy is tender, about 2 minutes. Stir in rice vinegar. Season soup to taste with salt and pepper.  Ladle soup into bowls. Sprinkle with green onions and serve

I put cut up chicken thighs into the broth and cook until the chicken is tender and then I follow the recipe.  I also add the spring onions to the soup as I freeze some of this away for future meals.   I hope you enjoy this as much as I do.

On a personal level I soak my chicken pieces in a very powerful product which releases the toxins from inside as well as off the surface.  I find that if I do this prior to cooking the broth that the top of my broth remains pretty clear.  If I do not do this soaking then I am having to ladle a dark yellow scum off the top of the broth.   If you wish to learn more about this please email me.  

Mushrooms  Can they help in preventing breast cancer

Getting your Vitamin D levels tested

Dr Mercola on 7 July 2014 brings a YouTube discussing whether you should get your Vitamin D levels tested on a regular basis.   Personally I believe that this is very good information on Vitamin D as so many diseases are related to low levels of this important vitamin.   Here is an excerpt of what Dr Mercola says in this article

Vitamin D has a number of potent anticancer effects, including the promotion of cancer cell death, known as apoptosis, and the inhibition of angiogenesis (the growth of blood vessels that feed a tumor)

A recent study links vitamin D optimization to improved cancer prognosis among those with a family history of cancer—regardless of the type of cancer involved—and a reduced risk of death from any cause

Vitamin D Supplementation

Sunlight and Breast Cancer

GreenMedia on 1 January 2015 provides information on a new study published in the “The Journal of Steroid Biochemistry and Molecular Biology identifies an overlooked root cause of breast cancer (cancer stem cells), as well as a natural intervention that has yet to be incorporated into the conventional standard of cancer care.”   Here is an excerpt and it is suggested that you take the time to read the full article (download here)


Titled, "Vitamin D compounds reduce mammosphere formation and decrease expression of putative stem cell markers in breast cancer," the new study brings to the forefront the role of breast cancer stem cells (BSCs) in breast tumor formation and their progression towards malignancy and treatment resistance. For many decades it was assumed that cancer results from DNA-damaged cells succumbing to fundamentally chaotic processes, 'going rogue' and reproducing clonally (making identical copies of one another), without an acknowledgment of the different types of cells that comprise tumors. The most salient difference is between the cancer stem cells (sometimes referred to as 'mother' cells) which are capable of theoretically infinite self-renewal and produce all the differentiated 'daughter' cells in a tumor colony, which themselves are not capable of living indefinitely. It is actually the existence of the much smaller number of cancer stem cells which causes cancer recurrence, as they are not only resistant to conventional chemotherapy and radiation, but their numbers can actually be increased (enriched) by these two 'therapies.' Therefore, any cancer therapy that ignores the cancer stem cell subpopulation in favor of killing the non-tumorigenic daughter cells in order to 'debulk' the tumor (i.e. shrink it), will not result in destroying the root of the cancer. To the contrary, it can generate the illusion of 'remission' while in fact making the remaining tumor colony far more malignant, setting up the conditions for aggressive recurrence years later.

Fallacy that sun exposure should be avoided

Dr Mercola on 21 July 2014 provides information on the dis-information put out with regards to sun exposure and your Vitamin D levels.   In this article he advises:

When UVB strikes the surface of your skin, your skin converts a cholesterol derivative into vitamin D3, which is critical for overall health and disease prevention

As a general rule of thumb, to optimize your vitamin D levels, you need to expose large portions of your skin to the sun – including your legs, back, arms, and chest, but avoid your face to reduce photoaging wrinkling

No sunlight and disease increases more than 1,000% with lack of this vitamin

On 26 January 2013 Prevent Disease provides more information with regards to this essential vitamin.  The article goes on to say:

Although D can be obtained from limited dietary sources and directly from exposure to the sun during the spring and summer months, the combination of poor dietary intake and sun avoidance has created D deficiency or insufficiency in large proportions of many populations worldwide. It is known that D has a wide range of physiological effects and that correlations exist between insufficient amounts of vitamin D and an increased incidence of a number of cancers. These correlations are particularly strong for cancers of the digestive tract, including colon cancer, and certain forms of leukemia.
