Big Pharma will never invest money into research on them because you cannot patent a naturally occurring substance. There is not money in it for them so they won't do it. That basically leaves universities to do real studies on it.

Its not that there isn't money in it though. The supplement business is huge business. I trust the studies and doctors pushing them less than big pharma by a long shot. Stay up late one night and watch all the infomercials on supplements and all the claims.

Herbs and supplements can be as powerful as any drugs and we should get as much valid info on them as we can before taking them.

I am certainly not against taking them. I take fish oil, vitamin D, Melatonin. I have taken SamE and L Methylfolate. If I wasn't on an SSNRI I would try 5HTP
