What type of iron does Geritol® multivitamin contain?

Geritol® multivitamin contains 16 mg of elemental iron per tablet, or 90% of the daily value for iron, in the form of carbonyl iron. Carbonyl is a lesser known and gentler form of iron when compared to more common iron salts, such as ferrous sulfate and ferrous gluconate.

How is Carbonyl A Gentler IRON?

Carbonyl is gentler because it is a pure form of iron that requires your stomach’s acid to break it down for absorption. This process of natural regulation by the body prolongs the iron absorption and makes carbonyl gentler on the system.
