L-Tryptophan, 500 mg, 60 Capsules

• Dietary Supplement 
• 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.

1 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take an additional 3 capsules before bed.
