Product information Peak Tryptophan 60 Caps
L-tryptophan is an essential amino acid (EAA) for humans and is therefore also required for muscle building and repair processes. As a precursor to serotonin, tryptophan is also a popular supplement often taken before bed. Tryptophan is optimized by a B vitamin complex for better assimilation and recovery. Directions for use: Consume 1 capsule of Tryptophan daily with as much fluid as possible, preferably at bedtime.
