Swanson, L-Tryptophan, 500 mg, 60 Capsules

Swanson L-Tryptophan provides L-tryptophan, an essential amino acid that serves as a precursor to serotonin and melatonin. Serotonin is a neurotransmitter involved in mood regulation, while melatonin helps regulate sleep-wake cycles. This capsule format offers convenient dosing for daily supplementation. L-tryptophan must be obtained through diet or supplementation as the body cannot produce it. Supplementation is commonly used to support mood, relaxation, and healthy sleep patterns. The product contains 60 capsules for daily use.
