L-Tryptophan

Discover why L-tryptophan is an essential amino acid and the important role it plays in the body's natural processes.

L-tryptophan is one of the nine essential amino acids required by the human body. Because it cannot be produced naturally, it must be obtained through food or supplements. It plays an important role in building proteins and serves as a precursor to several naturally occurring compounds within the body.

In our formulas, we include L-tryptophan as part of a carefully balanced nutritional formulation.

Amino Acids

Amino acids are the building blocks of proteins and are essential for many processes throughout the body. Of the 20 amino acids used to build proteins, nine are classified as essential, meaning they cannot be produced by the body and must be obtained through food or supplements.

L-Tryptophan

L-tryptophan is one of these nine essential amino acids. It is naturally found in a variety of protein-rich foods and serves as a precursor for several naturally occurring compounds involved in normal body functions.

What is the difference between tryptophan and L-tryptophan?

L-tryptophan is the naturally occurring form used by the body and the form commonly found in food supplements. The terms "tryptophan" and "L-tryptophan" are often used interchangeably.

What does "essential amino acid" mean?

An essential amino acid is one that the body cannot produce on its own. There are nine essential amino acids, all of which must be obtained through the diet or food supplements.

What foods naturally contain L-tryptophan?

L-tryptophan is naturally found in foods such as pumpkin seeds, soybeans, chickpeas, oats, nuts and other protein-rich foods.

What is L-tryptophan a precursor to?

L-tryptophan is a precursor to several naturally occurring compounds in the body, including serotonin and melatonin. As an essential amino acid, it also plays an important role in protein synthesis and many normal biological processes.
