NOW Foods L-Tryptophan Powder 950 mg – 2 oz

NOW Foods L-Tryptophan Powder is a free-form essential amino acid supplement designed to support relaxation, a positive mood, and healthy sleep patterns. Each 1-gram serving supplies 950 mg of L-Tryptophan in an easy-to-mix powder form, with approximately 57 servings per 2 oz container. Because the body cannot produce L-Tryptophan, it must be obtained through food or supplementation. L-Tryptophan is used by the body to produce serotonin and melatonin, important compounds associated with mood regulation and the normal sleep-wake cycle. It also contributes to proper immune system function as part of a balanced wellness routine. The unflavored powder can be incorporated into a nighttime routine as directed on the label. For another mood and relaxation amino acid, see NOW Double Strength 5-HTP 200 mg, or browse the full Vitamins A–Z collection.
