The Active Ingredient Is: L-5-Hydroxytryptophan (5-HTP)

L-5-Hydroxytryptophan is a natural precursor to the body's production of serotonin and melatonin, supporting everyday neurotransmitter availability and regulation of sleep and mood processes.

This form is a direct serotonin precursor packed in hypoallergenic, vegetarian capsules, designed to provide a readily absorbed amino acid derivative without extra artificial components.

What Does L-5-Hydroxytryptophan Do?

Dr. Mischoulon from Harvard University found that 5-HTP acts as a serotonin and melatonin precursor and crosses the blood-brain barrier more efficiently, helping normal mood and sleep regulation.

In line with EFSA guidance on nutrient function, this amino acid derivative supports normal neurotransmitter production and sleep-related processes as part of a balanced daily diet.
