Calcium is most well-known for its role in the formation of bone and teeth, but it also plays a role in keeping the heart and muscles functioning by governing muscle contractions. Magnesium is also a constituent of bone and controls potassium and calcium uptake, assists in electrical nerve activity, and manages the metabolism of carbohydrates. In the body, phosphorus is second in abundance only to calcium, and is necessary for bone growth, cellular health and acid-alkaline balance. Magnesium enhances the absorption of calcium, and works in tandem with calcium to allow muscles to contract and relax. Combined, these two essential minerals maintain in an intricately linked relationship that supports both muscle and nervous system function. Reacted Cal-Mag provides 200 mg of elemental calcium and 175 mg of elemental magnesium per serving, each ideally formulated using three mineral forms to ensure maximum absorption. While most mineral supplements use only a single source of minerals, which can easily overwhelm a single pathway of absorption and limit uptake, Reacted Cal-Mag leverages the benefit of multiple pathways of absorption by using three different mineral forms.
