Nuetro Isotónico is an invigorating sports drink with added amino acids: a 2:1:1 carbohydrate blend (Dextrose:Maltodextrin:Fructose) with added branched-chain amino acids (BCAA) and L-Glutamine. It contains minerals from easily absorbable sources and is anti-doping certified by Informed-Sport. It boasts incredible taste and digestibility, is suitable for vegans and does not contain allergens. Nuetro Isotónico (Isotonic and Energy Drink) is a high-quality powdered sports drink with a premium composition that provides all the necessary ingredients not only to maintain, but also to improve performance during training and competition. Fluid replacement, along with carbohydrate and electrolyte (mineral) replenishment during exercise, has been shown to prevent dehydration and therefore delay fatigue, resulting in improved performance (Wagenmakers, AJ, et al. JAP. 1993). Simply drinking water to replace lost fluids is ineffective because it can dilute blood plasma and consequently lower osmolality and electrolyte levels, producing the opposite effect to that desired. Similarly, consuming a beverage with a high mineral concentration is also ineffective because it has the opposite effect: an increase in plasma osmolality. This leads to a reduction in sweat rate and therefore a decrease in thermoregulatory capacity, meaning that body temperature increases (Gregor, RJ et al., Oxford: Blackwell Science; 2000), which not only reduces performance but also puts our health at risk. Isotonic drinks (Isodrink & Energy) contain an ideal matrix of three carbohydrate sources: dextrose, maltodextrin and fructose, in a ratio of 2:1:1. It has been shown that during prolonged physical exercise (1.5 hours or more), the use of carbohydrates absorbed through different transport systems (known as GLUT) facilitates gastric emptying and fluid absorption. Moreover, it is the only way to increase the rate of assimilation and oxidation of exogenous carbohydrates above 60 g/hour (Currell, K. et al., MSSE. 2008; Earnest, CP et al., JSCR. 2004). Also, something that few people know and/or many forget is that, during physical activity, the consumption of exogenous carbohydrates minimizes the immunosuppressive effects of intense exercise (Nieman, DC et al., EIR. 1998). Minerals, better known as electrolytes or salts, in addition to the benefits already mentioned, also improve the antidiuretic effect. As a result, the kidneys eliminate less fluid, which leads to improved hydration (Coso, JD et al., APNM. 2008). The most important is sodium (Na), as it is the mineral we lose the most through sweat and is essential for maintaining hydration during physical activity (NDA Panel. EFSA Journal. 2011). It also provides potassium (K) in adequate proportions and in an easily absorbable form: potassium citrate. As this is a highly technical and advanced formula, suitable for both beginners and experienced athletes, we have incorporated branched-chain amino acids (BCAA) and glutamine. Consuming these amino acids together with carbohydrates during training has been shown to reduce markers of muscle damage (Valentine, RJ et al., IJSNEM. 2008). Branched-chain amino acids (BCAAs), especially leucine, are also highly oxidized by the muscles, meaning they are used as an energy source, reducing glycogen utilization in favor of fat. In addition, the intake of these amino acids during exercise reduces Central Fatigue Syndrome (CFS), i.e. reduces the production of serotonin in the brain (a neurotransmitter linked to symptoms of fatigue and mood) (Kerksick, CM et al., JISSN. 2018). In addition, glutamine intake has been shown to reduce gastrointestinal discomfort during exercise due to improved intestinal permeability. In summary and conclusion, according to science, we can state that athletes should consume carbohydrate and electrolyte solutions to maintain blood glucose levels, prevent dehydration, and reduce immunosuppressive effects during intense physical activity (Kerksick, CM et al., JISSN. 2018). And lets not forget that Isodrink & Energy is 100% safe, having anti-doping certification from Informed-Sport (Lemon and Red Fruit flavors)
