From the Guidelines
Consult your healthcare provider before splitting Proferrin (heme iron) tablets, as there is no specific information indicating that Proferrin is designed to be cut in half, and splitting this supplement might affect its absorption or effectiveness 1. When considering the management of iron deficiency anemia, it's crucial to prioritize the most effective and safest approach to improve patient outcomes in terms of morbidity, mortality, and quality of life. The optimal drug, dosage, and timing of oral iron replacement therapy (IRT) for adults with iron deficiency anemia (IDA) are not clearly defined, but a once-daily dose of 50–100 mg of elemental iron may be a reasonable starting point 1.
Some key points to consider:
- The absence of an Hb rise of at least 10 g/L after 2 weeks of daily oral IRT is strongly predictive of subsequent failure to achieve a sustained haematological response 1.
- Intermittent oral iron has been reported to be at least as effective as daily dosing in raising Hb levels in certain populations, although less effective in boosting iron stores in the short-term 1.
- If you're considering taking a lower dose because of side effects like constipation, nausea, or stomach discomfort, or if the full dose seems too strong, discuss alternative dosing options with your doctor, who might recommend a different iron supplement with a lower dose or suggest taking Proferrin less frequently instead of splitting tablets 1.
- Heme iron supplements are specifically formulated to optimize iron absorption from animal sources, and altering the tablet might interfere with this specialized delivery system.
Given the information available, the most recent and highest quality study suggests that consulting a healthcare provider is essential before making any changes to your iron supplementation regimen, including splitting tablets, to ensure the best possible outcome for your specific condition 1.

From the Research
Heme Iron Supplementation
- The question of whether it is possible to take half a pill of Proferrin (heme iron) does not have a direct answer in the provided studies.
- However, studies have shown that heme iron supplements can be effective in improving iron status, but their efficacy may vary compared to other forms of iron supplementation 2.
- One study found that heme iron increased body iron, but to a lesser extent compared to electrolytic iron or ferrous sulfate 2.
- The optimal dosing regimen for iron supplementation is still a topic of debate, with some studies suggesting that alternate-day schedules and morning single doses may increase iron absorption and reduce side effects 3.
Iron Absorption and Dosage
- The absorption of iron from supplements can be affected by various factors, including the type of iron, dosage, and timing of administration 3, 4.
- High doses of oral iron may stimulate an acute increase in hepcidin, which can persist for 24 hours and reduce iron absorption 3.
- Splitting the dose or taking iron on alternate days may help maximize fractional iron absorption and reduce side effects 3.
- However, there is no specific guidance on taking half a pill of Proferrin (heme iron) in the provided studies.
Proferrin and Heme Iron
- Proferrin is a heme iron supplement, which may have different absorption and efficacy characteristics compared to non-heme iron supplements 2.
- Heme iron is generally considered to be better absorbed than non-heme iron, but the optimal dosage and administration schedule are still unclear 2.
- More research is needed to determine the optimal use of Proferrin and other heme iron supplements, including the possibility of taking half a pill.
