Tryptophan is an essential amino acid that plays a key role in regulating sleep. It is a precursor to serotonin, a neurotransmitter that helps improve mood and promote relaxation. Serotonin, in turn, is converted into melatonin, a hormone that regulates the sleep-wake cycle. Tryptophan supports the production of serotonin and melatonin, both of which are crucial for restful sleep.
