5-HTP

You can’t get 5-HTP from food. The amino acid tryptophan, which the body uses to make 5-HTP, can be found in turkey, chicken, milk, potatoes, pumpkin, sunflower seeds, turnip and collard greens, and seaweed.

5-HTP (5-Hydroxytryptophan) is a chemical by-product of the protein building block L-tryptophan.5-HTP is made from tryptophan in the body, or can be taken as a supplement. Supplements are made from extracts of the seeds of the African tree Griffonia simplicifolia.
