The two main ingredients when considering a sports drink are sodium and potassium to assist in keeping the fluid balance intact and carbohydrates that assist in providing the muscles with fuel. However the formulation of these components is important. Be aware that most sports drinks are isotonic or hypertonic which means that the osmolarity is the same or more than that of your body. This means that because of the high sugar content the rate at which gastric emptying takes place is slower and causes a slower absorption rate.
SOS Hydrate is hypotonic with an osmolarity lower than that of your body which means that your body will pass fast through the digestive tract and absorb nutrients faster than with other sports drinks.
