If the human body consumes too much glycine, it can not only be absorbed and utilized by the human body, but also breaks the body's absorption balance of amino acids and affects the absorption of other amino acids, resulting in imbalance of nutrition and affecting health. Milk-containing beverages produced with glycine as the main raw material can easily adversely affect the normal growth and development of adolescents and children.
