The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an important building block for serotonin, a brain chemical linked to mood, sleep and appetite control.

This formula pairs L-Tryptophan with niacinamide, lysine, hops and rosemary to help tryptophan function and its conversion routes in your body.

What L-Tryptophan Does?

L-Tryptophan is linked to the making and upkeep of serotonin, which helps steady mood and sleep rhythms as well as the body’s response to stress and appetite control.

Partner nutrients like niacinamide, lysine, hops and rosemary are added to help boost the activity and usage of tryptophan in the body.

This supplement isn’t meant to diagnose, treat, cure, or prevent any disease.
