Calcium Magnesium with Vitamin D3 maintains strong bones and teeth and helps prevent osteoporosis to reduce the risk of fractures later in life. 
Together, magnesium and calcium support mutual absorption and utilization. The optimal two-to-one ratio of calcium to magnesium ensures maximum calcium absorption and it prevents adverse gastrointestinal effects that can occur when the two minerals are combined.  Calcium Magnesium with Vitamin D is formulated with premium-grade, bioavailable Vitamin D3, the natural form synthesized by the body when skin is exposed to sunlight.Recommended Dosage: Adults: Take 1 to 3
caplets daily with a meal. Take a few hours before or after taking other
