Active ingredients
There are several categories of active ingredients:
Those that are difficult to digest or disruptive to the
stomach. A classic example is calcium carbonate, the most
widely used form of calcium. In a normal tablet or powder,
the calcium carbonate dissolves in the stomach acid and is
carried into the digestive system for absorption.
However, calcium carbonate releases carbon dioxide
when it dissolves in the GI, which usually produces gas in
the stomach. On the other hand, as people age, they
have less acid in the stomach, and thus a calcium carbonate tablet may pass through the stomach without dissolving. That, in turn, may lead to constipation. However, if
the calcium carbonate is taken in an effervescent formulation, the calcium dissolves in water, is readily available for
the body to absorb, and there is no risk of excessive gas
in the stomach or of constipation. effervescent tablet
