L-Tryptophan is an essential amino acid that helps to improve sleep, to reduce stress and to prevent and improve depressive processes.
It is a precursor to many neurotransmitters and neurochemicals, including serotonin and melatonin. Melatonin helps to improve sleep, and serotonin helps us to improve mood and mental health.
L-Tryptophan also helps women with the pain and premenstrual hormonal imbalance.
