5-HTP

What Is 5-HTP?

5-Hydroxytryptophan (5-HTP) is the direct precursor to serotonin, the neurotransmitter that regulates mood, appetite, and sleep. Thorne’s 5-HTP is derived from the seed of the African plant Griffonia simplicifolia and crosses the blood-brain barrier efficiently to support balanced neurotransmitter levels.

Key Benefits

• Supports healthy serotonin production for mood regulation
• Promotes natural melatonin synthesis for restful sleep
• Helps maintain healthy appetite and food satisfaction
• Supports a calm, balanced stress response
• May promote a positive emotional outlook

Who Should Take This?

5-HTP is best suited for adults experiencing mild mood imbalances, difficulty falling or staying asleep, stress-related eating patterns, or general feelings of low energy and motivation. It is particularly helpful for those who feel emotionally depleted or who struggle with nighttime restlessness.

How to Use

Take 1 capsule (50–100 mg) once or twice daily, typically in the evening or 30–45 minutes before bed to support sleep. For mood support, a morning dose may also be appropriate. Avoid combining with SSRIs or MAOIs without medical supervision. Start with the lower dose and adjust as needed.

Our Doctors’ Take

Our doctors recommend 5-HTP as a foundational support tool for patients navigating high-stress periods, sleep disruption, or mood fluctuations. Thorne’s formulation is trusted for its purity and bioavailability. We commonly recommend it as part of a broader nervous system support protocol, especially for patients who are not yet ready for or interested in pharmaceutical options.
