How Does NSI® L-Tryptophan work?L-tryptophan is an essential amino acid-meaning the body does not produce it on its own; it must be obtained through diet. It's found in small amounts in nuts, grains, beans, legumes, cheese, eggs, and meat.L-tryptophan breaks down into four different metabolites in the body. Most notably, it's converted to 5-HTP, which is then converted to serotonin-a neurotransmitter that helps regulate mood, sleep and appetite. Low serotonin levels in the brain are associated with poor mental health and sleep disturbances. Supplementing with L-tryptophan may help raise serotonin levels, promoting better mood, relaxation and rest.In addition, L-tryptophan is broken down into melatonin, a hormone that regulates the body's sleep-wake cycle, and the B-vitamin, niacin, which helps maintain healthy function of the nervous system, digestive system and skin.L-tryptophan also plays a part in the production of compounds called kynurenines, which have been found to suppress immune response, an effect that may benefit those with overactive immune function.NSI® L-Tryptophan is better because it: · Delivers 1,000 mg of pure L-tryptophan in one one-capsule serving. · Is safe for vegetarians.12807-DF01KD
