Great comment.

From prior research, the hormonal interactions around the thyroid and immune system are complex. You've boiled it down fairly well here as related to zinc.

Wasn't there some discussion about hydroxychloroquine being effectively only in conjunction with zinc as the hydroxychloroquine encourages cellular uptake of zinc. Ergo, zinc is the key ingredient.

Further, I seem to recall the book "The end of alzheimer's" (high recommend) talked alot about zinc wrt neurological health.
