Tryptophan

Definition:

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



Information:

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, there needs to be�enough�vitamin B-6, riboflavin, and iron in the body.

Tryptophan can be found in:

  • Turkey
  • Chicken
  • Milk
  • Cheese
  • Fish
  • Eggs
  • Tofu
  • Soy
  • Sesame seeds
