Too many consumers calcium deficient by Stephanie Sinden, B.Sc. Calcium supplementation for the prevention and treatment of osteoporosis is not new, but there are some new factors to consider. Moreover, if someone is getting less than two-thirds of the recommended daily calcium intake, they are probably deficient in other essential nutrients as well. It is important to understand that we are talking about calcium supplementation and not complete calcium substitution.
Foods are still the best source of nutrients.
It's best to recommend products that meet USP standards, as indicated on the label. Opinions vary as to how and when to take calcium supplements. Calcium carbonate products are most often recommended because they contain a higher percentage of elemental calcium and they are cost-effective. Calcium carbonate should be taken with food or immediately after eating to ensure adequate absorption. Antacids such as Tums and Rolaids are perfectly acceptable forms of calcium and are marketed as such.
