NOW L-Tryptophan 500mg 60 capsules.

NOW L-Tryptophan 500mg contains the essential amino acid L-tryptophan, which is a dietary precursor to serotonin (mood regulator) and melatonin (sleep hormone).

Adequate tryptophan intake supports positive mood, emotional balance, and the body's natural sleep-wake cycle. It differs from 5-HTP in that it must first be converted to 5-HTP, resulting in a gentler and more gradual effect.

Each capsule contains 500 mg. A typical dose is 1-2 capsules taken in the evening or before bedtime, separate from protein-rich foods to ensure optimal transport across the blood-brain barrier. 60 capsules per bottle.
