Instantly Dissolving Branched-Chain Amino Acids (BCAAs) in a 2:1:1 Ratio. The 3 Branched-Chain Amino Acids: Leucine, Isoleucine, and Valine in a 2:1:1 ratio, the most scientifically supported. Suitable for endurance and strength athletes. Allergen-free. Suitable for vegans. BCAAs 2:1:1 Instant is a powdered product made with Leucine, Isoleucine, and Valine. They are very easy to take due to their instant dissolution and pleasant flavor. These amino acids represent approximately one-third of all those that make up skeletal muscle protein. They are also essential amino acids because humans cannot produce them and they must be obtained through diet. Research to date concludes that consuming branched-chain amino acids (BCAAs) along with carbohydrates before, during, and after exercise has positive impacts on muscle protein synthesis, helps regenerate glycogen, delays the onset of fatigue, and maintains mental function during prolonged exertion. Furthermore, other observed benefits include reducing muscle soreness and strength loss that occurs after intense training sessions. And, like all Crown Sport Nutrition® products, it boasts exceptional taste, solubility, and digestibility.
