A: If you are just beginning to supplement with 5-HTP, Dr. Bowden recommends taking 50 mg, three times a day for the first two weeks. Ideally, you should take it 8 hours apart.

Q: Is 5-HTP safe for regular use?

A: 5-HTP is POSSIBLY SAFE when taking by mouth appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year.

Q: What are 5-HTP Capsules derived from?

A: 5-HTP is a drug-free amino acid derived from a plant that naturally increases the body’s level of serotonin, the chemical messenger that affects emotions, behavior, appetite, and sleep.
