Natural Factors 5-HTP 100 mg provides this free-form amino acid in timed-release caplets. 5-HTP is a direct precursor to serotonin, which helps promote healthy mood balance. It also helps relieve sleep disturbances associated with mood imbalance, helps relieve symptoms of fibromyalgia, and helps reduce the severity and duration of migraine headaches when taken as a preventive. The timed-release caplets gradually release 5-HTP to minimize gastrointestinal upset and allow a steadier rise in serotonin.
