Servings Per Container: 45

1. Promotes healthy mood and emotional well-being: 5-HTP TR contains 100 mg of 5-hydroxytryptophan, a precursor to the neurotransmitter serotonin. Serotonin is known for its role in regulating mood, and supplementation with 5-HTP can help promote a positive outlook and overall emotional balance.
2. Supports restful sleep: 5-HTP is also involved in the production of melatonin, a hormone that regulates the sleep-wake cycle. By increasing levels of serotonin and subsequently melatonin, 5-HTP TR can help improve sleep quality and promote a more restful night's sleep. The time release formula ensures a steady supply of 5-HTP throughout the night for sustained benefits.

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

5-HTP is a naturally occurring amino acid that acts as a direct precursor to serotonin in the brain.

This product is sourced from Griffonia simplicifolia seeds and uses a time-release matrix to provide a controlled release over several hours, with vegetarian and non-GMO characteristics noted in the formulation.

What Does 5-HTP Do?

5-HTP helps support normal serotonin production, which is associated with mood balance, appetite regulation and sleep patterns according to EFSA-aligned understanding of serotonin function.

The time-release delivery sustains serotonin-related support across the day, contributing to steady peripheral and central nervous system activity as described in the product facts.
