I seem to remember something about melatonin possibly helping remove spike proteins, along with shikimic acid and n-acetyl cysteine
Address this to Steve van Doorn; he is familiar with the research on that. Melatonin is attracted to mitochondria in the individual cells, where the effects of the spike protein are manifest.
I have read of NAC as therapeutic in this subject area but have encountered no clinical research on the matter. If you are aware of something useful please share it here. :)
