Vitamin D....Does it really help? (against Covid-19)

Updated: 3 days ago

I want to summarize a video by Mobeen Syed, M.D, about the influence of vitamin D levels and the severity of Covid-19 symptoms. Linked here:

This video explains in detail - results of the information gathered by the researchers of this study linked here: The Possible Role of Vitamin D in Suppressing Cytokine Storm and Associated Mortality in COVID-19 Patients

The basics of the video: Reduced vitamin D levels lead to increased level of CRP (C-Reactive Protein). CRP is considered a measurement of inflammation. This leads to increased

mortality because the 1st level of immune response (innate arm) is reduced which allows increased viral replication (viral load) in the first 7-10 days of infection. Then the 2nd level of immune response (adaptive arm) is much increased causing the overreaction and the development of the “cytokine storm” or acute inflammatory response. This is what causes the fluid buildup in the lungs as seen in the graphic below: link here to Dr. John Campbell’s video :

My patients have heard me preach about the importance of vitamin D supplementation for over a decade. Now we can see that having optimal levels of vitamin D is crucial for reducing symptoms and mortality from Covid-19. Vitamin D is (and always has been) number 1 of my Core 4 Program. There is much disagreement over what are optimal levels and how to reach optimal levels. To be sure we don't know exactly what this is, but we do know a safe and well accepted level for adults to reach is between 40 and 60 ng/ml. For more info on this, wait for my next blog on vitamin D.
