Tryptophan is an amino acid used to support mood balance, sleep quality, and emotional well-being. It plays a role in producing serotonin and melatonin, key brain chemicals that help regulate mood and the body’s sleep-wake cycle. Available in 500 mg & 1,000 mg strengths, it is typically taken between meals for better absorption.
Some people may experience dizziness, nausea, or fatigue. It’s important to follow dosage instructions, avoid mixing with certain medications, and consult your doctor before use.
