There has been some studies that perhaps Vitamin D3 deficiency was found in people contracting COVID-19 and possibly effecting the individual with severe outcomes.
What is Vitamin D - Mayo Clinic
It is interesting to me that coronaviruses seem to circulate here in the United States in the winter time. Vitamin D, is naturally produced by our body with exposure to sunshine. In the winter time, much of America is sunshine staved (due to length of day and frigid temperatures). Also, up to 35% of adults are deficient on Vitamin D.
I heard rumors that Dr. Fauci Sept/Oct 2020 said was taking Vitamin D, and in follow-on email he indicates he is taking 6,000 IU of Vitamin D. In one of the studies, it says 35% of adults are deficient in Vitamin D. I wonder if there could be some correlation between Vitamin D deficiency and the 25% of 65 and older people who end up in the hospital??

Interesting, what clinical Studies would correlate a deficiency of Vitamin D is found in people either testing positive for COVID-19 or hospitalization.
August 2021- Vitamin D deficiency and COVID-19: A case-control study at a tertiary care hospital in India
Conclusion: “Vitamin D status appears to be strongly associated with COVID-19 clinical severity. After COVID-19 confirmation, Vitamin D level should be measured in all patients and curative plus preventive therapy should be initiated.”July 2021: Vitamin D supplementation and COVID-19 risk: a population-based, cohort study”
Conclusions: “In this large, population-based study, we observed that patients supplemented with cholecalciferol (Vitamin D) or calcifediol (Vitamin D) achieving serum 25OHD levels ≥ 30 ng/ml were associated with better COVID-19 outcomes.”December 2020: Increased risk for COVID-19 in patients with vitamin D deficiency

Our study demonstrates an association between VitD deficiency and severity/mortality of COVID-19, highlighting the need for interventional studies on VitD supplementation in SARS-CoV-2 infected individuals.April 2020: Vitamin D insufficiency is prevalent in severe COVID-19
Conclusions VDI (Vitamin D insufficiency) is highly prevalent in severe COVID-19 patients. VDI and severe COVID-19 share numerous associations including hypertension, obesity, male sex, advanced age, concentration in northern climates, coagulopathy, and immune dysfunction. Thus, we suggest that prospective, randomized controlled studies of VDI in COVID-19 patients are warranted.
Based on that Data, what is Dan doing?
The risk of side-effect with Vitamin D is extremely low, the potential benefit seems extremely high. I would rather build-up a baseline before infection, so I am taking Vitamin D3 daily. I know Dr. Fauci takes 6,000 IU, but I personally take 5,000 IU of Vitamin D3 daily with Vitamin K2.
Side Note: Someday I may write an post on K2 benefits for heart.
