    this is a great product!! I take one with 3mg Now Foods Melatonin and sleep soundly thru the night. I wake up feeling refreshed and clear....long, long history of insomia that runs in family.

    Can't do without. Added this to my daily regime and notice within days that I was better able to handle stressful situations.

    Jarrow L-Trytophan

    Just read an article that said it was a myth that warm milk helps you sleep due to the tryptophan. Maybe it just doesn't have enough because 2 of these when I wake at 3-4am put me right back out.

    More Relaxed

    Posted by Reviewer1800343 on Aug 24, 2011

    I take this product at night with 5-HTP and Melatonin. It works relatively quickly. I do feel more relaxed when I go to bed and even when I do wake up, I am able to get back to sleep. I do think I am feeling less agitated and panicky, but is more likely to do with the 5-HTP than the Melatonin or this product.

    I love these

    Posted by seancollins on Feb 24, 2012

    They help me fall asleep. The raised levels of serotonin help reduce all sorts of my typical negative behaviors. I don't constantly crave snacks, my mood is generally positive, I don't have mood swings. I handle stress much better, but that might be because I take them in conjunction with the B-Right. But the snack cravings are a really great plus to having a good balance of serotonin.

    even better sleep, improved mood

    Posted by may291 on Apr 27, 2012

    Was suggested to me by my health care practitioner. I took one at bedtime each night. Even though I don't have a problem sleeping, sleep felt even a little more restful, and good for mood - depression and anxiety. I used this and Source Naturals brand, both were good.
