5-HTP Power [Nervous] contains hydroxytryptophan, a precursor to serotonin, an important neurotransmitter that helps regulate appetite, mood and sleep. Hydroxytryptophan is converted into serotonin in the body, which may help elevate mood, assist in controlling hunger and promote restful sleep. NSP 5-HTP Power is blended with three adaptogenic herbs--Siberian ginseng, ashwaganda and suma--that work synergistically with 5-HTP to help the body adjust to changes. It also contains vitamin B6 and zinc, which enhance the bioavailability of 5-HTP. Each capsule contains 35 mg of 5-HTP. CAUTION: If taking a prescription medication, consult a health care practitioner before taking this product. Pregnant or nursing women should seek the advice of a health care practitioner before using this supplement. Take 1 capsule three times daily with a meal. As a sleep aid, take 1-3 capsules of 5-HTP Power with an evening meal. We recommend a maximum of 3 capsules per day. Because the body rapidly excretes excess 5-HTP, taking 35 mg at each meal is generally more effective than taking 1-2 capsules per day of higher potency 5-HTP. Stock No. 2806-4 (60)
