Whats the difference between isotonic and hypotonic drinks?
An isotonic drink is specially formulated to have the same concentration of solutes as the blood. In other words, the amount of glucose (sugar) and electrolytes (salts) present match that of normal blood. The advantage of an isotonic drink is that it is rapidly absorbed into the body providing fast energy and hydration before and after sports. Hypotonic drinks are more dilute in concentration than blood so they will provide more fluid but less energy and electrolytes, and so are they are slower acting.
