Very helpful

Posted by 5152000038890959512 on Jun 15, 2016

I have opted to come off prescription anti-depressants because of the side effects. I take two 5HTP capsules at night and have found them to be of great benefit. I sleep well and my mood is more stable. I have been on them for about six months now and would definitely recommend trying them.

No effects felt

Haven't used yet

But I don't see how it could be very different from the 5HTP I'm currently using until the bottle is done. At this price point, it's definitely worth a shot!

Horrible nightmares

Posted by Reviewer2381562 on Mar 04, 2016

Gave me horrible nightmares. Switched to time release version which helps me sleep and relax. I can only take this in daytime now.

Made me suicidal

Posted by 5167703529071481388 on Jan 22, 2016

Took product for 3 days, gave me a gross tingling sensation in my upper body. Felt constipated and a sick feeling in my stomach for hours after taking it.
