    These are good

    Posted by Reviewer1265520 on Mar 21, 2011

    They are USP grade which means good I guess.hehe. I take them at night so I don't really notice too much of a difference in mood...

    This induces sleep within thirty minutes and I find if I do happen to wake in the middle of the night I have no trouble falling quickly back to sleep!

    I've had trouble falling asleep for years. I've been taking this for 3 weeks now, and ever since the first night I took it, I fall asleep. Which is amazing if you know my history of insomnia. No side-effect, no grogginess the next day, just peaceful and deep sleep. I will re order!

    Works well.

    No comparison between this and 5-htp. This is the original and doesn't have to metabolize in your body the same way. I've only used one other type, both were good. I've been using this for some time now.

    Sleepy and not sad

    Posted by Reviewer2042083 on Dec 26, 2010

    This safe tryptophan is great for using at night to help you gently fall asleep, and as a bonus, research has shown that it helps reduce depression the next day. Overall peace and calm. It isn't whack you on the head powerful, but you don't get wicked side effects from this either. I use in combination with Melissa leaves and chamomile.
