Why Endura Max: Take Endura Max every day to assist in maintaining normal muscle function and help alleviate the occurrence of muscle cramps and spasms. Endura Max contains ingredients which may protect your body against the oxidative stress and damage of physical training. Taurine may increase exercise performance by increasing VO2Max (maximal oxygen consumption), exercise time to exhaustion and maximal workload. Avoid Magnesium Deficiency: Exercising regularly and strenuously may require additional magnesium. Symptoms that indicate you may be deficient in magnesium include muscle cramps, muscle spasms, muscles that feel weak, feelings of fatigue and an increased susceptibility to stress. Magnesium is a vital nutrient that is involved in many important processes, including energy production. This formula contains a high dose of Meta Mag, a patented form of magnesium that's highly absorbable and easily digestable. Adults: Take 1 heaped scoop (11 g), twice daily, added to food or liquid (200 mL), or as directed by a healthcare professional.
