Substantial and immediate results are noticeable when we replace depleted electrolytes. This is especially true in the summer, when heat and exercise increasingly reduce the body's mineral supplies. Fluid balance inside cells is achieved when water intake includes proper amounts of ionic minerals. Hydration requires more than plain water, but too much sodium or sugar added to sports drinks can be counterproductive. All the systems of the body can be negatively affected if too much of the wrong elements are consumed when the body is stressed by heat or exertion. In this podcast, Val John Anderson of Mineral Resources International discusses how the body's cells access fluid and minerals in order to function properly.
