Thorne Research Griffonia

Griffonia is a natural source of 5-Hydroxytryptophan (5-HTP), the intermediate metabolite produced when the body initiates the process of converting the essential amino acid L-tryptophan to serotonin. Serotonin levels in the body are associated with the regulation of sleep, mood, aggression, appetite, temperature, sexual behavior, and pain sensation.


  • Enhances serotonin production
  • Increases serotonin levels for sleep enhancement, decreased sugar cravings, and better stress management
  • Can be taken with meals without competing with other amino acids
  • Made without flowing agents that can inhibit bioavailability

Directions: Take 1-2 capsules three times daily or as recommended by a health-care practitioner.

Each Capsule Contains:
5-Hydroxytryptophan 50 mg.
Vitamin B6 (pyridoxal 5'-phosphate) 3.4mg
Other Ingredients: Microcrystalline Cellulose, Hypromellose (derived from cellulose) capsule, Leucine, Silicon Dioxide.

For a good nights sleep

I have been taking Griffonia for many years now and it has helped me get a good nights sleep. I like that there is no residual effects the next day.
