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. Each caplet contains 100 mg of 5-HTP to increase serotonin levels without creating dependence. It is guaranteed pure and free from contaminants, contains no GMOs, and is suitable for vegetarians and vegans.
