L-Tryptophan is an essential amino acid that cannot be synthesized by the body, and must be part of our diet. It is found in most protein-based foods or dietary proteins. It is plentiful in Dairy products, Poultry , Fish, Seeds , Nuts, Chocolate, Spirulina, Bananas, and Red Meat. Tryptophan's most vital function is its role as a precursor for serotonin. Serotonin is a neurotransmitter that may promote not only sleep but also a stable mood. Seratonin is important for the development and functioning of many organs in the body. After absorbing L-tryptophan from food, our bodies convert it to 5-HTP (5-hyrdoxytryptophan), and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells. It also causes blood vessels to narrow. Changes in the level of serotonin in the brain can alter mood. *
