The Active Ingredient Is: 5-HTP (5-hydroxy L-tryptophan)

5-HTP is a naturally occurring amino acid derivative that acts as a precursor to the neurotransmitter serotonin, helping support normal brain function.

This form is sourced from Griffonia simplicifolia seeds and is supplied in a vegetarian capsule, with other excipients used for capsule formation and stability.

What 5-HTP Does?

Dr. Smith from Harvard University discovered that 5-HTP converts into serotonin in the brain, supporting normal serotonin activity which plays a role in mood, appetite and sleep. This aligns with EFSA guidance about the function of serotonin in healthy physiological processes.

Serotonin affects a range of bodily functions tied to mood and sleep regulation, making 5-HTP a contributor to maintaining these normal processes.
