Essential amino acids

Essential amino acids (9 types of which we know) are essential for the human body because they are not or only insufficiently produced by the body. That is why it is particularly important to supply them from external sources, preferably in the optimal amount and proportion.
L-tryptophan, like any other BioTechUSA product, contains safe, carefully selected ingredients.
