Filiquid of ferrous bisglycinate and ferrous fumarate, specifically at a dosage of 300 mg, is available in Canada. Ferrous fumarate is indicated for the treatment of iron deficiency anemia, with a typical dosage of 210 mg. However, one common side effect associated with its use is constipation.
Research indicates that the absorption of ferrous glycine sulfate can be enhanced when combined with calcium citrate. Notably, calcium citrate 200 mg (950 mg) tablets may play a significant role in improving iron absorption. Therefore, integrating calcium citrate into the regimen can potentially mitigate some gastrointestinal side effects, such as constipation, and enhance the overall efficacy of iron supplementation.
In summary, for those considering ferrous fumarate and ferrous bisglycinate, it may be beneficial to include calcium citrate 200 mg (950 mg) tablets to optimize absorption and minimize discomfort associated with iron supplementation.
