Description
The L-Tryptophan amino acid is a precursor of melatonin and serotonin. L-Tryptophan is a versatile essential amino acid that the body cannot produce, or can only produce in insufficient amounts. L-tryptophan is easy to replace with a balanced diet and good quality nutrients. Duck, pork, cottage cheese, and eggs are rich in L-tryptophan.

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.
