@jsg12206 Personally, I am not much on FDA approval since the US is so far behind Europe and other countries in terms of medical innovation. I focus on things that work (for me) regardless of FDA approval. I am a big fan of supplements that actually have proven results for helping with Long Covid and we know the FDA has never approved any of those. But could you please provide the links to the peer reviews? Always open to reading and analyzing anything that might potentially help. Thnx.
