5-HTP 100 mg Time Release Caplets

Serotonin is an important neurotransmitter that influences mood, appetite, sleep habits, and pain tolerance. Although serotonin is made by the body, the building blocks it needs are often lacking. 5-HTP from Natural Factors is a free-form amino acid and a direct precursor to serotonin.

By increasing serotonin levels, 5-HTP helps promote healthy mood balance and is useful as a sleep aid for people who have difficulty sleeping. It also helps relieve symptoms of fibromyalgia and can be used preventatively to help reduce the severity and duration of migraine headaches.

5-HTP is sourced naturally from the seeds of the African plant Griffonia simplicifolia. The timed-release caplets are designed to release 5-HTP gradually to minimize the mild gastrointestinal side effects sometimes caused by 5-HTP. It is guaranteed pure and free from contaminants, contains no GMOs, and is suitable for vegetarians and vegans.

  • Helps reduce the severity and duration of migraine headaches when taken as a preventative treatment
