What the brand says

Calcium is the most common mineral in the human body, and its importance to healthy bones and teeth is well known. Less well known, is the importance of magnesium and the many roles it has in regulating heart rhythm, blood pressure, cellular metabolism and intracellular balance of numerous other minerals, including calcium. Magnesium depletion in our soils and poor dietary choices have contributed to deficiency in an estimated 68% of the US population. Calcium supplementation without magnesium has been shown to decrease magnesium absorption, lower magnesium tissue levels, and increase magnesium requirements. Insufficient magnesium levels are associated with alterations in calcium regulation, glucose metabolism, energy production, response to insulin, and blood pressure. Research supports a 2 to 1 ratio of calcium to magnesium intake. Vitamin D is an important regulator of calcium metabolism and has profound effects on immune modulation. Research is indicating that seasonal respiratory infections are strongly associated with seasonal deficiencies in vitamin D from a lack of sun exposure. Vitamin D helps support a healthy immune response. These statements have not been evaluated by the Food and Drug Administration.
