Pure Encapsulations Electrolyte-Energy formula offers support for energy. During strenuous exercise your body loses electrolytes. These electrolytes include chloride potassium sodium magnesium and calcium. They’re responsible for supporting muscle functioning and keeping you hydrated. In addition you may be able to train for longer periods of time by replenishing your supply of electrolytes since they might decrease the level of exertion you feel. An amino acid known as l-tyrosine may also boost physical endurance and mental focus.
