Ferrous Fumarate vs. Ferrous Sulfate: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on September 16, 2024
Ferrous fumarate and ferrous sulfate are both iron supplements, but ferrous fumarate typically has a higher iron content per tablet than ferrous sulfate.
Key Differences
Ferrous fumarate, a compound of iron with fumaric acid, is a commonly used iron supplement with a higher iron concentration. Ferrous sulfate, another iron salt, is also widely used but typically contains a lower percentage of elemental iron per dose.
The absorption of iron from ferrous fumarate in the body is generally efficient, making it a potent choice for treating iron deficiency anemia. Ferrous sulfate, while also effective, may have slightly different absorption rates and is often prescribed in higher doses due to its lower iron content.
Ferrous fumarate is often recommended for those who require a higher iron dosage but want to limit pill intake. Ferrous sulfate, on the other hand, is a more traditional and common form of iron supplement, often recommended for general iron supplementation.
The side effects of ferrous fumarate can include gastrointestinal discomfort, though they are similar to those of ferrous sulfate, which may include constipation or stomach upset.
In terms of availability, ferrous fumarate is available in various formulations, including tablets and capsules, similar to ferrous sulfate, which is also widely available in multiple forms like tablets, liquid, and extended-release formulations.
