Energy GUM Bar + Caffeine is a premium gummy bar with a high-quality composition, which provides all the necessary ingredients to improve your performance during training and competition. It is an adaptation of Energy Gel + Caffeine in a gummy bar format: 30 g with a superb texture, easy to chew and swallow, preventing gastrointestinal problems. It contains two sources of carbohydrates: dextrose (in the form of glucose syrup) and sucrose. However, sucrose provides three types of carbohydrates, being a source of glucose and fructose. These are essential because carbohydrate intake during exercise has been shown to improve performance (Cermak, NM et al., SM. 2013; Pochmuller, M. et al., JISSN. 2016). In addition, recent research has shown that a high carbohydrate intake during exercise, especially in the case of prolonged exercise (>2.5 hours), improves neuromuscular function (Urdampilleta, A et al. Nutrients. 2020) and also enhances post-workout recovery, both in terms of muscle damage and energy, as it shortens the time for glycogen resynthesis (Viribay, A. et al. Nutrients. 2020). But in addition to the combination of carbohydrates, our exceptional formula offers even more benefits, as we have also incorporated: Minerals: Better known as electrolytes or salts, especially sodium (Na), which is the mineral we lose the most through sweat and is essential for maintaining hydration during physical activity (each bar provides approximately 112 mg) (NDA Panel. EFSA Journal. 2011). They also provide potassium (K) and magnesium (Mg), the loss of which may be implicated in muscle cramps. These minerals have been added in the form of highly bioavailable salts, such as magnesium citrate. Branched-chain amino acids (BCAAs): Consuming these amino acids with carbohydrates during exercise has been shown to reduce markers of muscle damage (Valentine, RJ et al., JSSNEM. 2008). Branched-chain amino acids are also highly oxidized by the muscles, meaning they are used as an energy source, reducing the use of glycogen in favor of fat. In addition, consuming these amino acids during exercise reduces Central Fatigue Syndrome (CFS), meaning that it decreases the production of serotonin (a neurotransmitter linked to symptoms of fatigue and mood) (Kerksick, CM et al., JSSN. 2018). Arginine: This amino acid, in addition to being a precursor of nitric oxide (NO), reduces lactate concentration and improves aerobic capacity. In addition, as a glucogenic amino acid, it can be used by the muscles as an additional source of energy. Taurine: Among other effects, it has antioxidant, metabolic and ergogenic properties (Galloway, SDR et al., JAP. 2008). Its administration, together with the other ingredients, has been shown to improve muscular endurance during physical exercise (Hoffman, JR et al., JCSR. 2008). It stabilizes cell membranes, facilitating the passage of potassium, sodium, calcium and magnesium through them (Bouckenooghe, T. et al., CNMC. 2006). Caffeine and guarana: We have added caffeine (in pure form and in the form of guarana), the most effective ingredient for directly improving performance, both in terms of endurance and strength (Grgic, J. et al., BJSM. 2019). In addition to activating the central nervous system (CNS), this process delays fatigue and optimizes the use of cellular fuels (glycogen and fat). But most importantly, it improves muscle contraction (Lopes, JM et al., JAP. 1983), hence its effectiveness, especially when fatigue begins
