5-Hydroxy-Tryptophan (5-HTP) by Thorne Research is an intermediate metabolite in the pathway from tryptophan to serotonin. Serotonin is involved in pain control, sleep, mood regulation, and appetite control.

5-HTP may be useful as nutritional supportive therapy to help alleviate the symptomatic effects of

• depression
• migraines
• sleep disorders
• anxiety disorders
• obesity
• carbohydrate craving
• headaches
• fibromyalgia
• epilepsy
• Parkinson's disease

Serotonin is important as a neurotransmitter for pain inhibition in a pathway origination in the brain stem. 5-Hydroxy-Tryptophan supplementation may help with chronic pain relief.
