Overview
Life Extension L-Tryptophan is a dietary supplement built around the essential amino acid L-tryptophan, provided in a 500 mg serving. The formula is positioned to help maintain healthy tryptophan levels in the body, which in turn supports the body’s natural production and maintenance of serotonin.
Because serotonin is associated with restful sleep and positive mood, this supplement is designed to support sleep, mood, and the body’s response to stress. It is also described as helping support satiety, or the sensation of fullness. The product is gluten free and Non GMO LE Certified.
The capsule format is intended for repeated daily use, and the directions note that it should be taken on an empty stomach and separated from protein or amino acids for best results. Life Extension also states that the ingredient has been manufactured through rigorous quality controls to support purity.
