L-Tryptophan is an essential amino acid, necessary as a building block for niacin (vitamin B3) and protein biosynthesis. It is also required for the production of the neurotransmitters serotonin and melatonin, which are involved in the regulation of appetite, mood, and sleep. Supplementation with L-tryptophan increases serotonin levels, which can influence the ability to manage stress, relax, and control food cravings. L-Tryptophan supports normal sleep-wake cycles and may be beneficial for individuals with altered sleep schedules. It may also assist those who experience occasional sleeplessness.
