Ferro-fumarate and folic acid tablets, along with liposomal ferric pyrophosphate, have been studied for their effect on the absorption rate of ferrous gluconate. Research has shown that ferrous gluconate in liquid form and ferrous sulfate at a dosage of 220 mg can be effective in treating iron deficiency. Additionally, a common question arises: does calcium citrate make you poop? This inquiry is often explored in relation to iron supplements, as the digestive changes caused by calcium citrate can influence overall nutrient absorption. Therefore, when considering iron supplementation, it is important to understand the interactions and potential effects of calcium citrate on bowel movements, particularly in the context of ferrous gluconate and its absorption.
