NOW Foods Branched Chain Amino Acids

Branched Chain Amino Acids (BCAA) are composed of the three essential amino acids Leucine, Isoleucine, and Valine. The BCAAs make up 1/3 of total muscle protein and thus, are very important for muscle growth and muscle repair. Athletes and body builders use Branched Chain Amino Acid supplements to maintain muscular strength and endurance, even after intense exercise and physical stress.

Branched Chain Amino Acids promote muscle growth and repair. Athletes and bodybuilders use Branched Chain Amino Acid supplements as part of their daily regimen. By stimulating formation of new muscles, the three BCAAs assist in the normal formation of leaner body mass. It also assists the muscles to heal after enduring physical stress and strain after rigorous exercises. Like other amino acids, Branched Chain Amino Acids participate in energy production. Physically active individuals will greatly benefit from healthy energy levels for endurance and vitality. According to experts, the BCAAs also strengthen the body’s physical response to fatigue from endurance sports and anaerobic exercises. Additionally, BCCA also help strengthening the nervous system’s response to fatigue to maintain mental sharpness even when feeling tired. Non-clinical studies suggest that Branched Chain Amino Acid supplements has the ability to regulate blood sugar levels to protect the blood vessels, kidney, eyes, and nerves from the harmful effects of high blood glucose levels. Branched Chain Amino acid supplements also help combat the health problems related to protein deficiency. Symptoms of protein deficiency include anorexia, depression, irritability, and headaches.

What are Branched Chain Amino Acids (BCAAs)? The BCAAs are composed of the three essential amino acids Leucine, Isoleucine, and Valine. They differ from other amino acids in term of structure because they have branched chain of atoms while other amino acids have straight chain or ring chain of atoms. In terms of metabolism, the three BCAA are metabolised in the muscles instead of the liver. Leucine, Isoleucine, and Valine makes up 33% or 1/3 of total protein in the muscles. During digestion, protein is broken down into simple amino acids which are used either to build muscles or produce energy. Given that, acquiring healthy levels of amino acids from the diet is critical to stimulate muscle development as well as produce healthy energy levels for athletic performance. Being essential in nature, Branched Chain amino acids are not produced by the body on its own. Thus, the diet and amino acid supplements must supply the body’s need of proteins. The best sources of amino acids are protein rich foods like red meat, fish, dairy products, whey, and eggs. Amino acid supplements containing the three BCAA are also a good alternative to replenish deficiency in case the diet is poor in proteins. Physically active individuals greatly benefits from the effects of Branched Chain amino acids to muscle growth and repair, as well as energy production. People who are exclusively on vegan diet are relatively prone to having protein deficiency and are good candidates to use supplemental amino acids to correct possible deficiency.
