L-Tryptophan 500 mg — Serotonin & Melatonin Precursor for Sleep & Mood Support

L-Tryptophan is an essential amino acid and the direct dietary precursor to serotonin and melatonin. Tryptophan crosses the blood-brain barrier and is converted to 5-HTP, then to serotonin, and ultimately to melatonin in the pineal gland — supporting mood balance, emotional wellness, and restful sleep. This 180-capsule value size provides a 3-6 month supply for consistent daily support.
