Amino acids are the building blocks of protein and are needed in several internal functions of the body. They are classified as \"essential\" or \"non-essential\", with essential amino acids meaning they cannot be manufactured by the body and must be supplied in the diet to maintain good all-round health. Amino acids can be further used by the body to create hormones, enzymes, neurotransmitters, antibodies and nutrient carriers. A suboptimal intake of the essential amino acids increases the body\'s need for the non-essential amino acids either through diet or supplementation. Foods that increase amino acid intake are meat, beans, cheese and eggs. Solgar DLPA 500mg (DL-Phenylalanine) Vegetable Capsules comes in a 2 vegetable capsule daily dosage, for easy absorption.
