I’d try to retrace my path through the research for you but I’m on mobile for the rest of the day. I got the anecdotal recommendations from Reddit and then was able to confirm everything on google scholar.

I will say that a lot of them were animal studies but I seem to recall at least a few human trials in the mix.
