NOW L-Tryptophan 500 mg is a premium-grade amino acid supplement designed to support relaxation, a positive mood, and healthy sleep patterns. Each vegan capsule provides 500 mg of free-form L-tryptophan, an essential amino acid that the body cannot produce and must obtain through food or supplementation.

L-tryptophan participates in the natural production of serotonin and melatonin, compounds involved in mood regulation and the sleep-wake cycle. This routine-friendly formula is suitable for adults seeking nutritional support for relaxation, emotional wellness, and restful sleep. A two-capsule serving supplies 1,000 mg of L-tryptophan, with 30 servings in each bottle.

Every lot of NOW L-Tryptophan is tested for Peak E and microbial contamination. The formula is vegan, non-GMO, halal, kosher, soy-free, dairy-free, egg-free, nut-free, and made without gluten.
