This seems to be good quality 5-HTP and I like that it is a very small capsule with fewer fillers. I use it to help my sleep for which it has limited effectiveness. It can give me diarrhea.

Absolutely Love It!

It's really a salvation when I have those anxiety attacks, one (or two) pills help me calm down immediately. When I have periods of stress I usually take one in the morning and one in the evening. Although if you have troubles with sleep you can take additionally Melatonin (3 mg) and Ltheanine (200 mg).
