For many people, taking iron supplements is associated with some mild GI discomfort. Iron is a strong mineral — think about an iron fence or a cast iron pot! A little nausea or irregularity may occur with iron supplementation. In fact, some very gentle types of iron are only gentle because they pass right through the system, are barely absorbed, and so have very little impact on raising iron levels.
The iron in FeRiva 21/7® is a type of iron designed to be both tolerated and also well-absorbed.
