Amino acids are building blocks of protein and the construction material of virtually all your body's lean mass. Amino acids are critical to our body's proper functioning. Their role includes repairing muscles, organs, nails, hair, skin, ligaments and glands.

Essential amino acids cannot be made by the body. You must get them from complete protein foods or combinations of incomplete vegetable foods. There are 9 essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan, and valine. Your body can make non-essential amino acids by itself from vitamins and other amino acids.

The term "non-essential" can be misleading since all amino acids are essential for proper metabolism and certain non-essential amino acids, such as glutamine, become very essential. The 13 non-essential amino acids are alanine, arginine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, hydroxyproline, proline, serine, & tyrosine.

Branched chain amino acids are essential for bodybuilders. Bodybuilders are required to workout on daily basis. The essential branched chain amino acids (BCAA's) are of special importance for athletes because they are metabolized in the muscle, rather than in the liver. After digestion once protein is broken down into individual amino acids these aminos can either be used to build new proteins or be burned as fuel to produce energy.

Glutamine, an amino acid, provides energy for workouts. Branched chain amino acids help you recover after exercise. They can reduce workout related injuries and provide you more energy for workout and all daylong.

N.A.G (N-Acetyl-L-Glutamine) is the acetylated version of the most abundant amino acid found in skeletal muscle tissue...glutamine. N.A.G is more stable and metabolically efficient at delivering glutamines biological effects over conventional Glutamine or Glutamine Peptides. N.A.G will play a role in increasing muscle volume, glycogen storage, growth hormone production, and it will also positively affect ones own immune system function.
