The Active Ingredient Is: L-Tryptophan

L-Tryptophan is an essential amino acid used by your body to help form serotonin and melatonin, hormones linked to mood and sleep regulation.

This form is an amino acid you can source and prep for supplement use to back up its role in serotonin and melatonin synthesis.

What Does L-Tryptophan Do?

L-Tryptophan helps support the normal production of serotonin and melatonin, backing mood regulation and sleep timing as part of the body’s normal function.

This links to standard physiological pathways recognised by NHS and EFSA that involve tryptophan in producing these hormones, without implying disease outcomes.

This product is not meant to diagnose, treat, cure, or prevent any disease.
