L-tryptophan

Other names: L-2-amino-3-(indole-3-yl)propionic acid

L-tryptophan, also known as L-2-amino-3-(indole-3-yl)propionic acid, is one of the essential amino acids, which are substances that the body needs but can't make on its own - we have to get them in our diet. L-tryptophan plays a key role in several important bodily functions. For example, it is essential for the production of serotonin, which is crucial for proper mood and dreams, and a deficiency of this neurotransmitter is linked to the development of depressive states. L-tryptophan is also involved in the production of niacin, a B vitamin that is important for digestion, skin health and the nervous system.

L-tryptophan is found in many protein-rich foods such as poultry, fish, eggs and nuts. But it is also often used in food supplements, where it is listed as a single ingredient or as part of a mixture of amino acids. L-tryptophan is also used in the pharmaceutical industry. Specifically, it is necessary for the production of certain drugs designed to treat depression and other mood-related conditions. Due to its ability to promote quality sleep, L-tryptophan is also often used in sleep aids. In addition, L-tryptophan can also be used in the cosmetic industry in skin care products, such as moisturizers, because it can promote healthy skin and coat.
