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 — the two key neurotransmitters governing mood, emotional balance, and sleep-wake cycles. Tryptophan crosses the blood-brain barrier and is converted to 5-HTP, then to serotonin, and ultimately to melatonin in the pineal gland. Supplemental tryptophan supports healthy serotonin and melatonin levels for mood balance and restful sleep.
