Essential amino acids (EAA) are amino acids that cannot be synthesized or are insufficiently synthesized by the body in which needs to be supplied via intake from food. Balanced diets and EAA are vital to maintain normal physical functions. Insufficient EAA intake will affect growth and bodily functions.
