Xtend Original BCAA Powder provides 7 grams of branched-chain amino acids (BCAAs) per serving in the research-backed 2:1:1 ratio of leucine, isoleucine, and valine. Leucine plays a particularly important role in stimulating muscle protein synthesis, while isoleucine and valine contribute to energy production and exercise recovery. The formula also includes 2.5 grams of L-glutamine, an amino acid commonly used to support post-exercise recovery and immune function during periods of intense training.
To address hydration needs, Xtend incorporates electrolytes that help replenish minerals lost through sweat during exercise. The sugar-free, zero-calorie formula makes it appealing to athletes and fitness enthusiasts seeking recovery support without additional carbohydrates or added sugars. The product is also NSF Contents Tested and Informed-Choice Certified, providing additional reassurance regarding ingredient quality and screening for banned substances.
While BCAA supplementation may be most beneficial for individuals training in a fasted state or those with lower dietary protein intake, its benefits may be less pronounced in people already consuming adequate high-quality protein. Nevertheless, Xtend remains one of the most established recovery formulas, offering a convenient combination of amino acids and electrolytes to support hydration, endurance, and muscle recovery.
