BCAA's 2:1:1 1lb

Sold By The Pound What is it? Branched chain amino acids(BCAAs) are a staple ingredient for anyone looking to improve their performance in the gym or a physical activity. BCAAs are essential amino acids, meaning our bodies cannot manufacture them and we must consume them via our diet. BCAAs comprise over 33% of the amino acid composition of human skeletal muscle(1). Benefits Used as fuel during intense exercise(2) Reduces exercise-induced muscle breakdown(3) Stimulates muscle protein synthesis(4) May promote strength recovery(5) Exert an ANTI-CATABOLIC and ANABOLIC effect on protein metabolism(6) Mixes easily in any liquid using a shaker cup Why use it? BCAAs are important, but Leucine in particular is the key ingredient. Leucine plays a major role in skeletal muscle metabolism by exerting an anabolic and anti-catabolic effect on protein metabolism. Leucine is often used as a marker of muscle protein synthesis, thus researchers believe it plays the major role in muscle formation and stability. Many researchers believe leucine supplementation itself is a way to prevent loss of skeletal muscle mass as well(7). Prescription Nutrition's BCAAs are instantized (no clumping, easily mixes in a shaker cup) and have a 2:1:1 ratio of L-Leucine, L-Isoleucine, L-Valine. This means there is TWICE as much leucine in the mix as normal BCAAs for in theory greater anabolism and anti-catabolic effects. How and when should one use it? There are 3 scenarios centered around BCAA use. Throughout the day Try taking 10+grams to promote fat loss and muscle sparing during dieting or other calorie-restricted states. Intra-workout Combine BCAAs with any fast-acting, high GI carbohydrate to keep the aminos and carbs flowing into the hungry muscles. Post-workout Use BCAAs with any of our supplements such as creatine or glutamine to promote anabolism and recovery. Directions As a dietary supplement, mix 1 scoop (10 grams) with 10-16 fluid ounces of your favorite beverage as directed or needed up to 3 times daily. Ingredients L-Leucine, L-Isoleucine, L-Valine, Soy Lecithin (Less than 1%).
