L-Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet. In the brain, tryptophan converts to serotonin, the neuto-transmitter that is responsible for feelings of well-being, calmness, personal security, relaxation, and confidence.* Serotonin is also involved in maintenance of a healthy appetite.* Some serotonin is converted in the pineal gland to melatonin, which helps to regulate sleep patterns.* Protocol For Life Balance™ L-Tryptophan is pharmaceutically pure - every lot is tested to be free of Peak E and microbial contamination.
