COVID PREVENTION and the Body's Dance Between Vitamins D, A and K2

COVID PREVENTION and the Body's Dance Between Vitamins D, A and K2

I am routinely asked for recommendations regarding Natural COVID Protection. 

Vitamin D is an important part of your 2020-2021 COVID and FLU Prevention program. PLEASE remember this fact and refer to the Corona Virus and Influenza Prevention program found here

Throughout the ongoing COVID-19 outbreak and pandemic, prevention is imperative. In 2020, there has been growing evidence mounting in Europe, demonstrating a significant negative correlation (i.e. inverse relation = lower the level of D associated with increased COVID Infection cases) observed between mean vitamin D levels and COVID-19 cases per one million population in European countries.

Several studies have also demonstrated the role of vitamin D in reducing the risk of acute viral respiratory tract infections and pneumonia due to direct inhibition of viral replication as well as it's anti-inflammatory and immunomodulatory power. Vitamin D supplementation has been shown as safe and effective against acute respiratory tract infections and in a critical meta-analysis it was suggested that “those people who are at higher risk of vitamin D deficiency during this global pandemic should consider taking vitamin D supplements to maintain the circulating 25(OH)D in the optimal levels." VERY INTERESTING is that the European OPTIMAL LEVEL FOR VITAMIN D LEVELS is 75-125nmol/L of Vitamin D!!!  This is a different and higher optimum level in comparison to our routine laboratories in the US (reference range 20-100 - with NO OPTIMUM levels). Hence, routine labs in this country use a reference range that allows doctors to MISS D deficiency in their patients. Worse is when many patients have their Vitamin D levels rise into therapeutic range, their physician will tell them to stop the Vitamin D. 

Vitamin D is part of an ancient complex molecular effort to protect our immune system in every imaginable way. But Vitamin D's ability to do its work is created by the molecular dance on receptors of the human cell when A, D, and K work together. These lipid-based molecules are all powerful antioxidant nutrients which are intricately bound through shared receptors. They balance and enhance each other, and as a group, profoundly influence genes, immunity, inflammation, and the healthy balance of life in our body.

Vitamin D may be one of the most important nutrients in our nutritional armamentarium—and currently, one of the most misunderstood. Vitamin D can help us fight infections and reduce the risk of multiple sclerosis, diabetes, heart disease, cancer (colon, breast, skin and prostate, etc.), osteoporosis, cavities, lupus, rheumatoid arthritis, mood disorders (depression) and much more. There are 1000’s of peer review studies on vitamin D, stretching all the way back to 1922.

Vitamin A deficiency is more common than we realize because vitamin A-rich foods are rarely eaten and vitamin A toxicity has been overblown, to our profound immunological detriment.

Vitamin A is necessary for optimal mucosal immunity—and is a key nutrient in balancing the pro-inflammatory cytokines. (CYTOKINE STORM caused by COVID often leads to incipient death).

  • Carotenes are not an adequate or safe substitute for vitamin A in supplements, even though they have long been recommended as a substitute. Carotenes are not efficiently converted to vitamin A in most individuals, and they can create cleavage products that form free radicals, interrupt vitamin A’s protective function, and thereby potentially raise the risk of cancer.

Most important, vitamins D and A are an ancient and inseparable team that evolution has honed through time. They must be supplemented together in order to not create a “functional” deficiency of either one. Excess D will create a “relative” deficiency of A, even when dietary levels are adequate. And vice versa.

Receptors for vitamin A and vitamin D are found in every cell and when they dock at the same receptor, they initiate a cascade of responses throughout the entire body.

Vitamin K2 is not to be forgotten as it serves as a molecular ‘link’ between hormonal receptors and intracellular signaling pathways. As is a true hormone, like vitamin D and A, they circulate throughout the body eliciting specific effects on the activity of cells situated remotely from their point of origin.

Vitamin K2 as you remember from former blogs, enhances vitamin D’s impact on bone, and protects against vascular disease, atherosclerosis. 

Osteo Px is my strongest recommendation for your D supplementation for immune support during this COVID and FLU 2020-2021 season.


I believe that I have outlined a very strong, proactive, yet simple viral prevention program and it is on my website homepage

 Please stay tuned, as I continue to educate thereader about WHY I make my specific recommendations for you and your friends and family to maintain health and wellness during these challenges times!

Always there for you!
