How is Caltrate® different from other calcium supplements?
Caltrate® products have 20% more calcium per tablet than most other leading brands of calcium supplements. Caltrate® has been clinically tested for proven absorption and is made with calcium carbonate, the most concentrated form of calcium. This means you need to take just two tablets per day to get the calcium and the vitamin D3 recommended by the Institute of Medicine for adults 51 years and older (1200 mg). Caltrate® is available in four different formulas to suit your calcium supplement needs.
