This essential amino acid is a foundational nutrient for the hormones serotonin and melatonin, the duo critical for healthy mood and sleep cycles. It’s also the precursor for the biosynthesis of niacin, the B-vitamin which regulates digestion of protein, carbohydrates, and fats. Supplementing with L-tryptophan is a small investment that can yield significant returns for your health.
