    Natural 5-HTP

    Posted by Reviewer2761994 on May 16, 2011

    I have trouble sleeping & was in hopes that this would be a miracle cure; however, I didn't experience a remarkable change in my sleep by taking them & after reading some of the side effects I decided not to take them for any long term period of time.

    Taken in conjunction with Melatonin this helps me fall asleep but I still awaken numerous times through out the night and wake up in the morning feeling a little groggy. I am also concerned that when I stop taking these my sleeping patterns will actually worsen but I will see and update this review accordingly.

    No longer the Best 5 Htp

    Posted by Reviewer2533909 on Dec 16, 2013

    I've been using this for a few years now , tried many other brands but this just seemed to suit me perfectly . Mainly for depression Then they changed the formula to suit vegan. Logic tells me that should not have made any difference at all. It is almost as though it is stronger. I started having nightmares. Stopped taking for a while but depression came back . So started taking again but in the morning. I feel nauseous and vaguely "High" Haha . It does work for the depression but the nausea is awful . I really don't know what to do.

    Failed me!

    Posted by NatursKathy on Feb 09, 2009

    I was planning to replace my Xanax addiction, what I use before bed time. Unfortunately, did not work! Now I'm on a weening away process with Xanax, and use this natural product as a hope for help in the process.

    Milder form of 5htp

    Posted by Reviewer1265520 on Nov 19, 2010

    I've tried other brands... this one seems to be pretty mild. A lot of the brands are actually different... I got the best results from Natrol 5htp caps.

    Not sure

    Posted by 4900496852315445713 on Mar 30, 2015

    I don't know if this has improved my mood or anything but it seems to make me sleep a lot longer than normal. Since I have been taking it (1 capsule at night) I've noticed that I don't fall asleep any faster (which is why I bought it) but I sleep more and wake up slightly tired. I will continue to take it and see if anything changes.
