Premium recovery supplement with Anti-Doping certification and scientific study. With 2 sources of carbohydrates and protein. With added glutamine. Its effectiveness is guaranteed by our own scientific study. Anti-Doping certified by Informed-Sport. Easy absorption and delicious flavor. 3:1 PRO Recovery ST is a UNIQUE, top-quality recovery supplement that provides all the necessary nutrients to optimize recovery in strength-endurance sports. Its effectiveness in mitigating performance loss and fatigue, and accelerating both recovery and post-workout muscle function, has been scientifically proven by the University of Greenwich. 3:1 PRO Recovery ST has a premium blend of the best ingredients: Carbohydrates: combines two high-glycemic index sources, dextrose and maltodextrin, in a 1:1 ratio, which is ideal for optimizing energy recovery processes (glycogen replenishment) after physical activity (Mata, F. et al., Euro-American Journal of Sport Sciences. 2018). Proteins: A UNIQUE combination of two rapidly absorbed hydrolyzed (pre-digested) protein sources: hydrolyzed beef (All Beef®) and hydrolyzed whey protein isolate (Optipep® Sport 90). These protein sources are rapidly assimilated (Wilson, J. et al., JISSN. 2006; Naclerio, F. et al. In preliminary studies of the quality and composition of the All Beef® raw material (2015) based on Pennings, B. et al., AJCN. 2013) and high in essential amino acids, thus promoting post-workout muscle recovery. We have also added L-Glutamine, as this amino acid, among other functions, appears to improve the functioning of the immune system by serving as fuel (Calder, PC et al., AA. 1999), primarily for macrophages and lymphocytes. In this regard, supplementation with whey protein and hydrolyzed beef protein (All Beef®) can also benefit the immune system. On the one hand, the amino acids in whey protein are signaling molecules that, among other things, regulate lymphocyte function (Bumrungpert, A. et al., JMF. 2018). On the other hand, All Beef® beef protein has demonstrated a greater adaptive immune response when ingested with carbohydrates, due to a decrease in HNP1-3 (a marker of humoral immunity), indicating a lower risk of infection (Naclerio, F. et al., JAP. 2016). This matrix of ingredients is specially designed for optimal absorption and for the rapid and effective delivery of all its nutrients to the muscle cells.
