Question: how much htp 5 is safe?
Answer: 5-HTP Dosage Because 5-HTP is an unregulated supplement, there are few scientifically valid guidelines for proper dosages. For depression, a recommended dose of 5-HTP is 150 milligram (mg) to 300 mg per day. For primary fibromyalgia syndrome, a recommended dose is 100 mg, three times a day for one month.
