Tryptophan is an essential amino acid, which means your body cannot produce it you must get it from your diet or supplemental sources. Tryptophan is an amino acid needed for normal growth in infants and for nitrogen balance in adults.

The body uses tryptophan to help make niacin and serotonin. Serotonin is thought to produce healthy sleep and a stable mood. In order for tryptophan in the diet to be changed into niacin, the body needs to have enough iron, riboflavin and vitamin B6.

Food sources for tryptophan include: cheese, chicken, eggs, fish, milk, nuts, peanut butter, peanuts, pumpkin seeds, sesame seeds, soy, tofu and turkey.

Texas Transdermal’s Amino Acid patch contains the proper dose of Tryptophan.
