The half lives of a lot of these things is pretty long — so it doesnt really surprise me. I must admit prior to CoVID, I was not up on vitamins and recommended doses. So this protocol states one should have levels followed. This is a very data driven approach to this protocol
With the long half-life and infrequent administration, you would have a sequence of exponential decays resulting in varying concentrations in the body. Wouldn’t it make more sense to reduce dosage, administer daily and maintain a more constant concentration in the body?
