Dr. Ken Redcross is an internal medicine physician with a concierge practice in New York. He wrote the book “Bond: The 4 Cornerstones of a Lasting and Caring Relationship with Your Doctor,” and in this interview, he shares his views on the prevention of COVID-19 through natural means.<br /><br />• Research shows COVID-19 patients with a vitamin D level between 20 ng/mL (50 nmol/L) and 30 ng/mL (75 nmol/L) had a sevenfold higher risk of death than those with a level above 30 ng/mL<br />• Having a vitamin D level below 20 ng/mL was associated with a 12 times higher risk of death from COVID-19<br />• Other research suggests your risk of developing and dying from COVID-19 virtually disappears once your vitamin D level gets above 30 ng/mL (75 nmol/L). To ignore this seems foolish in the extreme, especially since vitamin D supplementation is both safe and inexpensive<br />• Other nutrient deficiencies may be at play if you’re having a hard time improving your vitamin D level. One of them is magnesium, which is required for the conversion of vitamin D into its active form<br />• Recent research shows you need 244% more oral vitamin D if you’re not also taking magnesium and vitamin K2
