The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an essential amino acid that acts as a building block for proteins and a precursor in making serotonin and melatonin, which help with mood and sleep regulation.

This variant is pharmaceutical-grade free-form L-tryptophan, suitable for vegetarians, with a strong focus on purity and rigorous quality testing during production.

What Does L-Tryptophan Do?

L-Tryptophan contributes to normal sleep and mood regulation through its role in serotonin and melatonin production, in line with accepted nutritional functions.

Research indicates improvements in sleep parameters and mood in some individuals when used appropriately, with evidence cited by Dr. Hartmann of a university in relation to sleep quality after bedtime use.

It supports normal immune and nervous system function as part of the body’s serotonergic pathways, aligning with standard EFSA-compatible explanations of amino acid metabolism.

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