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.
For other uses, talk with your doctor or follow the manufacturer's recommendations.
If you suspect an overdose, contact a poison control center or emergency room immediately.
You can get in touch with a poison control center at (800) 222-1222.
If you miss a dose of 5-HTP, try to take it as soon as you remember.
However, if it is almost time for the next dose, skip the missed dose and resume your regular dosing scheduled.
Don't double up on doses to make up for a missed dose.
