L-TRYPTOPHAN Overview Information. L-tryptophan is an amino acid, a protein building block that can be found in many plant and animal proteins. L-tryptophan is called an âessentialâ amino acid because the body canât make it. It must be acquired from food.
That's because. tryptophan uses the same means of transport into the brain as other amino. acids, and has to compete against them to cross the blood-brain barrier. As it happens, tryptophan is the least abundant amino acid. Forced to. fight for access against the more common amino acids, it's left waiting.
