No Real Impact

Posted by 5614542857841632437 on Sep 29, 2012

Perhaps my expectations were too high but the 5-HTP didn't improve my sleep nor counter my anxieties. If anything, it seemed to make me a little drowsy during the afternoon.

Be careful with 5-HTP

Posted by Reviewer1767326 on Sep 23, 2011

I have food allergies and this product is very good for me. But be careful not to purchase a sound-a-like brand that I was unfortunate to buy by accident. My mood went way down and I was told that 5-HTP products are NOT all the same. This one is a good one.

One of the best

Posted by Reviewer1706966 on Feb 19, 2010

This is a form of 5-HTP which is vegan (no gelatin caps) and comes at the reasonable dose of 50mg which most people tolerate better than 100mg.
