Tryptophan is an essential amino acid that plays an important role in the functioning of the nervous system. It also participates in the formation of niacin, which is necessary for the synthesis of the neurotransmitter serotonin. How does it work? The use of tryptophan promotes healthy and quality sleep, relieves symptoms of depression and anxiety, improves mood and raises the pain threshold. Tryptophan is commonly used to treat insomnia and sleep disorders such as sleep apnea. Tryptophan has been noted as possibly effective in alleviating premenstrual dysphoric disorder (PMDD).
