It is carcinogenic to experimental animals; it may cause adverse reactions including nausea, anorexia and asthmas. Avoid combination with monoamine oxidase inhibitors.; ; Nutritional supplements:; ; Tryptophan contained in egg white protein, fish meat, corn meal and other amino acids are limited; content in cereals such as rice is also low. It can be combined with lysine, methionine and threonine for enhanced amino acids. It can be supplemented to corn product at the content of 0.02% tryptophan and 0.1% lysine, being capable of significantly improving the protein potency.tryptophan is one of the 21 amino acids comprising a protein. Tryptophan is a component of the skin's natural moisturizing factors.
