Promote Restful Sleep & Positive Mood

Our bodies manufacture 5-HTP (5-hydroxytryptophan), a neurotransmitter that regulates the sleep cycle and initiates sleep, from tryptophan as a precursor to serotonin and melatonin production. But, since most tryptophan is converted by our bodies into niacin (Vitamin B-3), 5-HTP is preferable to tryptophan. In addition, 5-HTP gives more consistent results in promoting and maintaining sleep, even at lower doses, and it improves the quality of sleep by increasing REM and deep sleep (stages 3 and 4) without lengthening total sleep time. Studies show that it helps to decrease the time it takes to fall asleep and decrease the number of times sleepers awaken during the night. For best results, take near bedtime with some carbohydrates like fruit or juice and start with a low dose for 3 or 4 days and increase if needed.

5-HTP increases endorphin levels and has a positive influence on mood, promoting a sense of well-being. It can be useful for obsessive-compulsive disorder and mild depression. Studies have shown that 5-HTP is as effective as SSRIs but with fewer and more mild side effects. It also acts as an appetite suppressant and may be helpful for those trying to lose weight.

Jarrow Formulas' 5-HTP (5-Hydroxytryptophan) is an extract of Griffonia simplicifolia seeds from coastal West Africa. Purity is assured by HPLC.
