Neurotransmitters are responsible for regulating a number of different functions in the body to ensure mental and physical health. Serotonin is a neurotransmitter that helps to regulate appetite, and serotonin plays a vital role in regulating mood. Your body needs serotonin to be able to produce melatonin and melatonin is vital for regulating the biorhythms of the body that regulate sleep-wake cycles. L-Tryptophan is an amino acid that is vital for the production of serotonin. L-Tryptophan is an essential amino acid and must be supplied from the diet in sufficient quantities to support the abovementioned functions.
