Vitamin Expert Q: What supplements do you recommend to help protect a person from Covid-19? A: I like the protocol formulated by Dr. Paul Marik, Professor of Medicine and Chief of Pulmonary and Critical Care Medicine at Eastern Virginia Medical School. He recommends the following supplement for prevention and early infection: Vitamin D3, Vitamin C, Quercetin, Zinc, and Melatonin. I am also impressed with some research being done on Andrographas. Come to Jeffreys and I would be happy to share the full protocol and dosages. We carry all the recommended supplements; and our suppliers are manufacturers you can trust. Brian King, R. PH.
