Creatine is produced within our bodies and therefore, is not a foreign compound. Creatine is a natural by-product of liver, kidney and pancreas metabolism. Initially the amino acids Arginine and Glycine are combined to form glycocyamine. A few more enzymatic steps result in the formation of methyl guanido acetate. The nomenclature methyl guanido acetate is commonly referred to as creatine. Once inside the muscle, creatine is enzymatically phosphorylated to form creatine phosphate (CP). CP acts as an energy reservoir for those situations requiring intense recycling of ADP (Adenosine Di-Phosphate) back into ATP (Adenosine Tri-Phosphate), such as occurs under anaerobic conditions.

Amino Nitro Max consists of the Branched Chain Amino Acids (BCAA). The Big Three amino acids and L-Glutamine, L-Alanine, L-Ornithine, Taurine, Chromium and Vitamin B-6, most essential in muscle repair. As freeform amino acids, they are quickly absorbed by the system without extensive liver metabolism. Take a good dose of the BCAAs immediately after each workout to assure tissue repair.

Twinlab Amino Fuel Tablets are an amino acid supplement containing a high tech anabolic formula with 2000 mg (per tablet) of L-carnitine, branched chain amino acids and peptide-bonded and free amino acids. All of these readily absorbable amino acids come from the highest quality whey protein.

L-LYSINE is an essential free-form amino acid which acts as a precursor for other amino acids, including L-carnitine (needed for fat metabolism). L-lysine is crucial for the formation of collagen, a major part of the bodys connective tissues. L-lysine also contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs cycle.

L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion as well as DNA synthesis.

BCAA Complex contains the ideal 2:1:1 ratio of the free-form, crystalline branched chain amino acids L-Leucine, L-Isoleucine and L-Valine combined with the conditionally essential amino acid L-Glutamine. The higher amount of Leucine reflects it’s importance in muscle metabolism as the most effective branch chain amino acid for stimulation of protein synthesis and it is more readily utilized for energy. BCAAs exert an anticatabolic effect by reducing the breakdown of protein, thereby protecting muscle tissue. Glutamine is a preferred source of fuel for the intestinal cells and is in high demand by skeletal muscles following physical exertion. Vitamin B6 enhances amino acid metabolism.

L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, and to enkephalins, special peptides that subdue messages of physical discomfort. Tyrosine is also a constituent of amino sugars (glycosaminoglycans), special compunds which have important roles throughout the body. L-Tyrosine is also a precursor for the protective skin pigment melanin.

L-Phenylalanine, an essential amino acid, is a precursor of the amino acid tyrosine and to a whole series of neurotransmitters and hormones. Phenylalanine is first converted to tyrosine, which becomes L-dopa, which then converts to norepinephrine, a key neurotransmitter and adrenal hormone. L-Phenylalanine is also a direct precursor to PEA (Phenylethylamine), another important neurotransmitter.

Amino Acids are the building blocks of protein. Protein availability is an essential element of building muscle, when used as part of a low-fat diet and exercise program. Research shows that when taken orally, peptide–bonded amino acids, the most easily digested form, are absorbed faster than other types of proteins.

L-Alanine is a crystalline, free form amino acid. The liver can convert L-alanine into glucose as needed for muscle fuel; when glycogen stores are low, it can convert the glucose into glycogen. Glycogen is a storage form of glucose.
