5HTP is greatly helping myself and my daughter with our symptoms of fibromyalgia. I have tried low doses of antidepressants in the past but nothing worked as well to improve my sleep as 5-HTP has. I take 200mg per night. My type comes with several essential cofactors to assist in proper seratonin production. No side effects for me, unlike with the other drugs. I'm considering it for more members of my family. We have a genetic sleep and pain disorder. Hopefully we can find the right dose for all of us. I advise everyone to see a qualified ND or sympathetic MD before self dosing to be extra safe but side effects are rare thankfully.
