I dunno. Seems like an electrolyte replacement drink or tablet makes sense if the person wants a more immediate impact instead of waiting for a balanced meal to work it's way through the system. This would be the case for extended periods of difficult/fast riding where the person is using lots of fuel, electrolytes, and water.
