L-Tryptophan is converted into melatonin, a hormone that regulates sleep. Supplementation may improve sleep quality and reduce the time it takes to fall asleep.
L-Tryptophan is an essential amino acid that serves as a precursor to serotonin and melatonin. Serotonin influences mood, and melatonin regulates the sleep-wake cycle. Supplementation with L-Tryptophan may increase melatonin production, leading to improved sleep quality, reduced sleep latency (time to fall asleep), and increased sleep duration. It may also positively influence mood due to its role in serotonin synthesis.
