Natural Factors Natural Factors - 5-HTP 200mg - Time Release 200 mg, 60 Time-Release Tabs
Natural Factors 5-HTP 200mg Time Release - Natural Factors 5-HTP 200 mg provides a higher dose of this free-form amino acid in timed-release tablets. 5-HTP is a direct precursor to serotonin, which helps promote healthy mood balance and can be used as a sleep aid without creating dependence. The timed-release tablets gradually release 5-HTP to minimize gastrointestinal upset and allow for a steadier increase in serotonin. This formula is non-GMO and suitable for vegetarians and vegans.
