Chelated Iron vs. Gentle Iron: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 20, 2023
Chelated iron refers to iron bound to an organic molecule for better absorption, while gentle iron is a form of iron supplement designed to minimize gastrointestinal side effects.

Key Differences

Chelated Iron is a type of iron supplement where iron is bound to amino acids or other organic molecules. This bonding enhances the absorption of iron in the body. Gentle Iron, on the other hand, is a term often used for iron supplements that are formulated to be easier on the digestive system and to reduce side effects like constipation and nausea.
The chelation process in Chelated Iron helps in reducing the interaction of iron with other dietary elements, thus improving its bioavailability. In contrast, Gentle Iron supplements typically contain iron in a form that is less likely to cause gastrointestinal irritation, often using forms like iron bisglycinate.
Chelated Iron supplements are often recommended for individuals with certain absorption disorders or those who need a more efficiently absorbed form of iron. Meanwhile, Gentle Iron is particularly beneficial for those who experience stomach discomfort, constipation, or other side effects from standard iron supplements.
The effectiveness of Chelated Iron is due to its ability to remain intact through the stomach and reach the small intestine for absorption. In contrast, Gentle Iron focuses on a slow-release mechanism or the use of less-irritating forms of iron to minimize digestive issues.
From a cost perspective, Chelated Iron supplements are often more expensive due to the complex process involved in their production. Gentle Iron supplements, while also potentially more costly than standard iron supplements, offer the advantage of improved gastrointestinal tolerance.
