Healthy muscles matter. Muscles are the engine that your body uses to move itself. Of course, muscles are not like your car engine, but they do turn energy into motion. It is impossible to do anything physically without your muscles, so taking care of them will help strengthen and support your body. Muscle Ease is a magnesium-based formula that supports healthy muscle function, providing essential minerals and herbs to support your engine. Potassium, sodium, calcium and magnesium all function as electrolytes, substances that work to balance fluids in the body and transmit electrical impulses. As electrolytes, potassium and magnesium both play key roles in muscle contraction and particularly relaxation.
