Have been taking these in combination with NAC and other vitamin supplements for major depression and anxiety with great results after only 2 weeks. No side effects to date. Would recommend.

Thanks for your feedback!

Not for me

Sadly this supplement, which I was trying to help with my depression symptoms, made me quite sick to my stomach. Which in turn made me more unhappy. I hope it works for others. I was disappointed.

Thanks for your feedback!

Great Product , will buy again

Very effective

I take 5-HTP for OCD and anxiety, but I've found 5-HTP works best for sleep (take L-Tryptophan for the former). 1 pill and I begin to feel sleepy in about 1 hour. Works for relaxation too (especially combined with L-Theanine) but if you take it by day you have to get busy or distracted doing something so you don't fall asleep.
