What happens to tryptophan in the body?

When you consume L-tryptophan, your body absorbs it and changes it to eventually become a hormone called serotonin. Serotonin transmits signals between your nerve cells and also narrows (constricts) blood vessels. The amount of serotonin in the brain can affect mood.

Is the human body able to make tryptophan on its own?

It is essential in humans, meaning that the body cannot synthesize it and it must be obtained from the diet. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3.

Where is the tryptophan located?

Tryptophan is found in a wide variety of protein-containing foods, including eggs, cheese, meat (especially turkey), fish, wheat, rice, potatoes, and bananas.

What are symptoms of tryptophan deficiency?

Is 5 HTP the same as tryptophan?

5-hydroxytryptophan (5-HTP) is a chemical that the body makes from tryptophan (an essential amino acid that you get from food). After tryptophan is converted into 5-HTP, the chemical is changed into another chemical called serotonin (a neurotransmitter that relays signals between brain cells).

How can I get tryptophan naturally?

Where is tryptophan found in the body?

Tryptophan is the sole precursor of serotonin and, once consumed, tryptophan is distributed throughout the human body in the circulatory system. Unlike the other 19 amino acids, approximately 75\% to 85\%, of circulating tryptophan is bound to albumin, with some estimates as high as 95\%.

Why is tryptophan called an essential amino acid?

It is known as an “essential” amino acid because the body does not produce it. Tryptophan is important to the functions of many organs in the body. When you consume tryptophan, your body absorbs it and changes it to eventually become a hormone called serotonin.

What are the health benefits of tryptophan?
