NutraKey products are Pharmaceutical grade ultra-pure for maximum bioavailability. Pure amino acid with no fillers or additives. HPLC verified.Branched-chain amino acid (BCAA) is the name given to three of the eight essential amino acids needed to make protein: leucine, isoleucine and valine. They are called branched-chain because their structure has a ‘branch’ off the main trunk of the molecule. The combination of these three essential amino acids makes up approximately one-third of skeletal muscle in the human body. The body cannot produce BCAA’s on its own, but must obtain through diet or supplementation. In order to get energy, the body can actually break down muscle to get these BCAAs. By supplementing BCAAs during and after your workout, you can prevent muscle tissue breakdown, which occurs as a natural part of metabolism.Almost 1/3 of muscle tissue is composed of BCAA which are needed for muscle growth, the maintenance of muscle tissue and to preserve muscle stores of glycogen. BCAA’s can turn on the main muscle growth pathway in muscle tissue which can increase protein synthesis and help prevent muscle tissue breakdown after strenuous exercise. Each serving of NutraKey ultra-micronized BCAA provides the three free form branched chain amino acids; L-Luecine, L-Valine and L-Isoleucine in the proper 2:1:1 ratio and is available in either pure powder or capsules.Benefits of Branch Chain Amino Acids: Essential for Protein Synthesis Increase Strength Improves Nitrogen Retention Speeds Muscle Recovery Enhanced Energy Levels Reduces Muscle Fatigue Helps Preserve Lean MuscleMuscle tissues are comprised of two proteins, actin and myosin. The main components of the two proteins are leucine, isoleucine, and valine, which are called branched chain amino acid (BCAAs) for their molecular structures. BCAAs accounts for about 35% of the essential amino acids contained in myoproteins. Replenishment of BCAAs increases the raw materials for muscle tissues, contributing to muscle building.BCAAs make up 1/3 of muscle protein. During intense exercise the BCAAs are expended from muscle tissue at a rapid rate, leading to increased muscle tissue breakdown. BCAA-5000 is a high potency formula with a specific ratio of branched chain amino acids designed to enhance absorption and muscle tissue recovery. Amino acids play a vital role in muscle growth and recuperation, weight management and many other important bodily functions. BCAAs are metabolized directly in the muscle and are especially useful to athletes because they may improve nitrogen retention by sparing other amino acid groups for repair and rebuilding.
