Dr. Erin Barrett, director of product innovation and scientific affairs at Shaklee Corporation, has suggested that adding electrolytes to the body can provide an extra boost to keep it functioning properly and running efficiently. These essential minerals, such as sodium, potassium, calcium and magnesium, keep the body hydrated, muscles functioning and energy levels up. When we don't get enough, we can develop muscle cramps, fatigue and weakness, and potentially more serious issues like low blood pressure. The supplement is often overlooked in its importance for its hydration effects.
