Most sports drinks, gels, and electrolyte-replacement products contain one (sodium) or two (sodium + potassium) electrolytes. While the sweet taste of sports punch can initially encourage drinking, in the long run, it can ultimately hinder fluid intake when athletes max out on sugar before meeting their electrolytes needs. Besides over-emphasizing sugar, many products over-emphasize salt, which is an electrolyte that is already in excess in the diet. elete Add-In products have a lower emphasis on sodium, but emphasize magnesium, an essential electrolyte often omitted from many hydration products because it is more expensive. Magnesium is essential to proper muscle function and it acts as the team captain of the electrolytes, ensuring that electrolytes are directed to where they are needed so they can perform their roles.
