The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an essential amino acid that your body can't make on its own and must obtain from outside sources. This pure amino acid is produced through natural fermentation and offered in a vegan capsule form for dietary supplement use.

What Does L-Tryptophan Do?

L-Tryptophan acts as a precursor to serotonin and melatonin, supporting mood balance, relaxation and sleep regulation. Dr. Lieberman at the National Institutes of Health found that sleep quality can improve with L-Tryptophan supplementation.

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