Actually CS, I'm wrong, I have had a few adaptogen drinks! Rise Kombucha is one that I really liked actually ... I also tried a local adaptogenic mushroom "coffee" and I can't say I would recommend it, but others that tried it really liked it!
The only thing I can say is that, for the Rise, for example, some of the drinks contain things like holy basil, which I believe can interact with certain medications ... I guess I would just say use the same caution you would use with any supplements? (non-medical opinion of course! I just happen to know holy basil is one I need to be wary of).
Slightly off the question, but if plain-Jane komucha is of interest, I love Remedy ... it's so good, and gives the same little bite that a sparkling wine gives. Nothing special about it though; just another tasty alternative at cocktail hour And I think it still has the gut-health advantage since it's still fermented.
