L-Tryptophan is a crucial amino acid, acting as the origin of the sleepy hormone melatonin, niacin, and serotonin. Serotonin is a central nervous system neurotransmitter, offering a soothing effect and assisting in the regulation of emotion, sleep, and metabolic rate. American diets are typically lacking in L-Tryptophan, with the average individual following a high-protein diet receiving less than 1.5 grams daily. Supplementing with L-Tryptophan could provide nutritional assistance for tranquil sleep and a brighter mindset!*
