There is a little known study that was done about using Gatorade to negate blood clots while flying. The Gatorade somehow affects the blood viscosity in the lower extremities.
I’m sure that PepsiCo, which owns Gatorade, would love a rumor like that to start too. But it would have no more real basis in fact than Pepsi yielding therapeutic benefits if taken once-a-day.
Among other things, Gatorade contains brominated vegetable oil, which introduces bromine into the system, a halide that blocks absorption of Iodine (also a halide, but the one that the body actually needs).
