L-Tryptophan 500 mg
By Source Naturals Mood, Relaxation, Sleep The essential amino acid L-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep/wake cycles. L-Tryptophan also supports immune functions because it is 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.* Serving Size:3 Capsule Servings Per Container:20 Disclaimer Amount Per Serving Iron (naturally occurring)575 mcg L-Tryptophan1.5 g Other Ingredients: gelatin (capsule), dibasic calcium phosphate, microcrystalline cellulose, silica, magnesium stearate Dietary
