Ferrous fumarate and ferrous lactate are commonly used forms of iron supplementation. One product that combines these elements is a micronized and microencapsulated ferric pyrophosphate, offering a dosage of 325 mg of ferrous fumarate. Additionally, some formulations include 75 mg of iron tablets. It’s important to be mindful of potential side effects, such as diarrhea, which can occasionally occur with iron supplements. To mitigate this, some choose to combine these iron supplements with calcium citrate, as it may help reduce gastrointestinal discomfort. Therefore, if you are considering ferrous fumarate or ferrous lactate, be aware of the possibility of diarrhea and explore the use of calcium citrate to support your supplementation regimen.
