What makes Best BCAA Powder by BPI Sports different is that it uses “Oligopeptide-enzymatic technology” to formulate the amino acids into a bond. According to the manufacturer, this helps the body utilize the BCAAs faster so you get better results. Gonzalez AM, Trexler ET. Effects of Citrulline Supplementation on Exercise Performance in Humans: A Review of the Current Literature. J Strength Cond Res. 2020;34(5):1480-1495. doi:10.1519/JSC.0000000000003426 Flavor Options: 12 flavor options include artic ice, blue raspberry, fruit punch, blue lemonade, cherry lime, grape, green fusion, passion fruit, rainbow ice, snow cone, sour candy, watermelon ice Marketed as “the best-selling, most advanced BCAA drink mix on the planet,” XTEND certainly has a cult following. It is definitely a high-quality product. With 7 grams of BCAAs per serving, it also offers a higher dosage than many competing products.

This article needs additional medical references for verification. Please help improve this article by adding appropriate references. Unsourced or poorly sourced material may be challenged and removed. Secondly, the overall amount of BCAAs needs to be adequate for it to be effective. Xtend gives you a total of 7 grams of branched-chain amino acids. Throw in glutamine, and you have a total of 9.5 grams of overall amino acids.The watermelon flavor tasted exactly like a watermelon. Or rather, it tasted like about a pound of watermelon condensed into one glass, meaning it’s a more intense flavor than the actual fruit. PeakO2®. This ingredient is scientifically developed to increase performance and power with a blend of six natural, organic-certified adaptogens. My Favorite Flavor: Lemon lime is good. Grape and fruit punch are also okay, but I wasn’t too impressed with the other flavors.

Calorie restriction proportionally decreases the consumption of all three macronutrients (fat, carbohydrate, and protein), and for many years, the contributions of restricting these individual macronutrients to the effects of CR have been explored. It is now generally believed that the restriction of protein in a CR diet is not great enough to fully explain the benefits of CR (Speakman et al., 2016). However, restriction of protein reproducibly extends the lifespan of flies (Bruce et al., 2013; Grandison et al., 2009; Lee et al., 2008; Mair et al., 2005) and rodents (Solon‐Biet et al., 2014; Weindruch et al., 1986). Many studies have shown PR improves metabolic parameters in rodents, such as glucose tolerance, insulin sensitivity, circulating triglycerides, and other blood lipids (Fontana et al., 2016; Maida et al., 2016; Solon‐Biet et al., 2014, 2015). Also, my recovery time is better with Xtend, and it does help reduce workout soreness (although we sometimes embrace feeling sore because we know we did something!). Pros Ingredients: Do the amino acids and other ingredients come from quality sources? Are the formulas well-balanced and transparent?Watson P, Shirreffs SM, Maughan RJ (December 2004). "The effect of acute branched-chain amino acid supplementation on prolonged exercise capacity in a warm environment". European Journal of Applied Physiology. 93 (3): 306–14. doi: 10.1007/s00421-004-1206-2. PMID 15349784. S2CID 20597074. Our testers at GGR take pride in our rigorous evaluation process, examining the product from all angles and giving it an unbiased look. Our expertise includes credentialed pros like registered dietitians, certified personal trainers, certified nutrition coaches, and professional athletes. The BCAAs are strong agonists of the amino acid‐sensitive kinase mTOR complex 1 (mTORC1). mTORC1 regulates a wide variety of downstream biological processes—most notably those related to growth and proliferation such as ribosomal, protein, nucleotide, and lipid synthesis through integration of nutrient and hormonal cues; this has been reviewed in great detail elsewhere (Babygirija & Lamming, 2021; Kennedy & Lamming, 2016). Put simply, amino acids promote the lysosomal localization of mTORC1. Binding of the BCAAs, especially leucine, to Sestrin2 relieves the inhibitory action of Sestrin2 on the GATOR2 complex, allowing the Rag GTPases to bind to mTORC1 and recruit it to the lysosome (Chantranupong et al., 2014; Wolfson et al., 2016). Several other molecular mechanisms by which BCAAs, especially leucine, regulate mTORC1 recruitment by the Rag GTPases have been discovered (Han et al., 2012; He et al., 2018; Zhu et al., 2021). At the lysosome, mTORC1’s kinase activity is allosterically activated by the binding of Rheb‐GTP (Yang et al., 2017). BSN doesn’t overdo the sweetness in their BCAA powder (the sweetness comes from sucralose in this case). Now the caveat here is how much BCAAs do you need to boost recovery and for it to really matter. And more importantly, what ratio is needed. I’ll cover that when we get to the ingredients below. Where to Buy Xtend BCAAs

Easier fat-loss, more energy and increased muscle gain are all benefits BCAA supplementation can make, but a well-rounded diet should be able to cover most of your muscle-building needs, without you having to turn to BCAA powder or BCAA tablets. Lots of Food Has High BCAA Content Obviously, you want to choose the best tasting BCAA powder available. However, even these might not taste so great to you. In that case, use these tips to make the BCAA powder taste better. 1. Drink BCAA Cold Yu D, Richardson NE, Green CL, Spicer AB, Murphy ME, Flores V, etal. (May 2021). "The adverse metabolic effects of branched-chain amino acids are mediated by isoleucine and valine". Cell Metabolism. 33 (5): 905–922.e6. doi: 10.1016/j.cmet.2021.03.025. PMC 8102360. PMID 33887198. But what actually are BCCAs? What are the benefits? Are there any side effects and, most importantly, does the average gym-goer truly need them?Branched-chain amino acid supplements aren’t just for bodybuilding anymore. BCAAs have been shown to support muscle protein synthesis for maximum muscle recovery and training potential. Plus, BCAA supplements that contain electrolyte blends, like XTEND BCAA powder, can support hydration before, during, and after your workout. Sahlin K (1986). "Muscle fatigue and lactic acid accumulation". Acta Physiologica Scandinavica. Supplementum. 556: 83–91. PMID 3471061. Another experiment testing different protein:carbohydrate ratios in both sexes on reproduction and lifespan found that female mice maximize reproductive health and longevity at different ratios compared with male mi
