The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an essential amino acid that serves as a direct precursor to serotonin, which regulates mood, sleep and relaxation.

This formula includes cofactors such as vitamins B2, B6 and folate and minerals to support the enzymatic conversion to serotonin, and the product is vegan with GMP-certified manufacturing.

What Does L-Tryptophan Do?

L-Tryptophan plays a role in serotonin production, a neurotransmitter associated with mood and sleep regulation in line with EFSA guidance.

The body converts L-Tryptophan to 5-HTP before producing serotonin, and cofactors in the formulation support this metabolic pathway. Dr. Shaw of a major university has reported findings related to this amino acid in the context of sleep and mood research.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
