The recommended dosage for iron bisglycinate is 210 mg of ferrous fumarate. High ferrous fumarate tablets contain 210 mg, and it’s important to be aware of the potential side effects associated with ferrous glycine sulfate and ferrous gluconate, such as those found in Fergon. Additionally, when considering iron supplements, it’s beneficial to look for options that include calcium citrate chelate, as this can enhance absorption. Incorporating calcium citrate chelate into your regimen may help maximize the benefits of iron supplementation. Always consult with a healthcare professional before starting any new supplement, especially those containing calcium citrate chelate, to ensure they align with your individual health needs.
