L-tryptophan 500mg - 90 capsules

Protein forming amino acid

The essential amino acid, which must be supplied with food, is mainly involved in the formation of proteins in the body, which in turn form tissues such as muscles, mucous membranes and skin.
Furthermore, L-tryptophan is a serotonin precursor and can be converted into serotonin in the organism.

L-tryptophan in food

As a component of protein, L-tryptophan is found in both animal-based and plant-based foods. The differences in quantity are very small, so that vegetarians or vegans are also sufficiently supplied with the amino acid.
Soybeans, cocoa powder, cashew nuts or oats are particularly rich in L-tryptophan. Good animal sources are chicken meat, salmon and chicken eggs.
