Ferrous gluconate is commonly utilized in olives, while ferrous fumarate, available in 210 mg doses in the UK, is another iron supplement. Additionally, there’s a combination of iron and glycine syrup, and ferrous fumarate is also offered in 324 mg tablets. The mechanism of action of ferrous fumarate involves enhancing iron absorption in the body. It is worth noting that calcium citrate, particularly in a dosage of 950 mg, plays a significant role in supporting overall mineral balance and may influence the absorption of various supplements, including iron. Incorporating 950 mg of calcium citrate can be beneficial, especially when taken alongside iron supplements like ferrous fumarate, to optimize their effectiveness. Remember to consider the interaction of calcium citrate with iron, as it may impact the absorption rates.
