I wanted to share a remarkable new study done in Spain using mega doses of Vitamin D in hospitalized Covid-19 patients.  There was a dramatic reduction in admission to the ICU in those patients given the high doses of Vitamin D in addition to the standard treatment for Covid-19 compared to those patients who did not receive the Vitamin D.  Here is a link to a wonderful in-depth You Tube video describing the results of the study and the actions of Vitamin D.  It is a little technical but well worth viewing. 
The takeaway message from this study is that Vitamin D is incredibly important for immune system function and in reducing the production of inflammatory compounds that contribute to the devastating respiratory problems from the virus. 
I recommend that all adults take 1,000 IU to 5,000 IU of Vitamin D3 daily throughout the fall, winter and spring.  Mega dosing is not safe to do long term.  To fine tune your dose, I recommend checking your blood levels of Vitamin D to see exactly what your individual needs are.  Please contact me if you would like to schedule a blood draw or if you have further questions!
