Product Description

Package Quantity: 1 | Size: 120 Tablets

Dietary supplement. Mood, relaxation, sleep. The essential amino acid L-tryptophan helps support relaxation, restful sleep, and feeling better. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is in the body's precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality. (These statements have not been evaluated by Food and Drug Administration.

5.0 out of 5 stars Perfect sleep aid, July 4, 2007

This review is from: Source Naturals L-Tryptophan 500mg, 120 Tablets (Health and Beauty)
I am a true insomniac who does not want to take prescription sleeping pills due to side effects and dependency issues. So I tried this. Works really well for me. Does not knock me out. Just eases me into a natural sleep. Price at Amazon is half of what I would pay at local health food store.

4.0 out of 5 stars This helps me get the sleep I need, February 19, 2008
Amazon Verified Purchase(What's this?)
This review is from: Source Naturals L-Tryptophan 500mg, 120 Tablets (Health and Beauty)
This doesn't make me sleep like Unisom, but it does help me fall asleep naturally. When I wake in the morning, I don't have that "sleeping pill hangover." I just feel refreshed.

5.0 out of 5 stars Great help for insomnia, January 15, 2008
Amazon Verified Purchase(What's this?)
This review is from: Source Naturals L-Tryptophan 500mg, 120 Tablets (Health and Beauty)
I'm a chronic insomniac, but I hate the hung-over, dragged-out feeling the next day after taking over-the-counter sleep meds. Tryptophan is the stuff in turkey that makes people sleepy after Thanksgiving dinner. I take it with the herb valerian, and I quickly zone out with no fuzzy feeling the next day.
