Buying advice

When choosing a 5-HTP supplement, consider dosage (typically 50-300mg), additional ingredients like vitamin B6 or magnesium for cofactor support, and third-party testing for quality assurance. Start with a lower dose to assess tolerance. Consult a healthcare provider before use, especially if taking antidepressants or other medications.
