This includes calcium. The most important factor in choosing which calcium supplement to take, is its solubility. This is of critical importance because the body can absorb calcium only in this form. This is especially important as we grow older because older people do not secrete normal amounts of stomach acid which makes the absorption of calcium much more difficult. For this reason and because we want to have only the finest, highest quality products available, we've chosen a liquid gel capsule for its calcium, ensuring the greatest benefit possible for your body.
Calcium carbonate is the most widely used form of calcium.
Most brands are made from eggshells or oyster shells. We have chosen to use a liquid source, however. Even though it is a more expensive source, it certainly is more soluble and thus more beneficial to the body. Forms of calcium that are in a formula including an antacid are the worst forms to use. First, they are from a shell source, making them less soluble, and second, by reducing the acid in the stomach, you reduce the absorption of the calcium.
