Top Picks Summary
Ferrograd C Tablets
Ferrograd C Tablets are positioned as a best-in-class option for ferrous sulfate supplementation because they pair a commonly used iron salt formulation with vitamin C to boost absorption while using a formulation designed to minimise gastrointestinal side effects. Compared with the simpler, lower-cost Galfer Capsules they offer a technical advantage in bioavailability and tolerability, and they are generally more affordable than liquid or specialty alternatives like Floradix or Spatone when judged on mg of absorbable iron per dose.
£3-8 GBP
Galfer Capsules
Galfer Capsules represent a market-leader profile for ferrous sulfate by focusing on a straightforward, reliably dosed capsule that delivers iron economically and at scale for widespread use. Compared with branded or adjunct-fortified competitors like Ferrograd C and Floradix, Galfer's chief advantage is financial — lower cost-per-mg of elemental iron and broad availability — though it may lack the added absorption cofactors or gentler delivery formats offered by the other products.
£5-12 GBP
Spatone Iron Sachets
Spatone Iron Sachets stand out as an alternative to ferrous sulfate capsules by offering a naturally derived liquid iron source marketed for gentler stomach tolerance and suitability for sensitive patients. Technically, Spatone typically supplies lower elemental iron per serving and commands a premium price compared with capsule-based ferrous sulfate options, but it is often preferred by users who prioritise tolerability or a liquid sachet format over maximum iron density.
Floradix Iron Tablets
Floradix Iron Tablets are recognized for combining iron with botanical extracts and complementary vitamins, aiming to enhance absorption and reduce common side effects associated with straight ferrous sulfate capsules. Financially they sit above many generic capsule options like Galfer, but their technical advantage is the inclusion of additional nutrients that can improve iron uptake and patient adherence relative to basic ferrous sulfate products.
£7-18 GBP
Boots Iron Tablets 14mg
Boots Iron Tablets 14mg offer a pragmatic, accessible ferrous sulfate solution as a pharmacy-own-brand product that balances a modest dose with strong retail availability and competitive pricing. Compared with higher-dose or fortified competitors such as Ferrograd C and Floradix, Boots' main strengths are affordability and convenience for maintenance dosing, though those needing higher absorption or specialised formulations may prefer the other listed options.
£1-5 GBP
What the research says about iron supplementation
Multiple clinical studies and health guidelines support oral iron, including ferrous sulfate, as an effective first-line treatment for iron deficiency and iron deficiency anemia. Improved haemoglobin and increased ferritin are commonly seen within a few weeks of appropriate oral supplementation. Research also highlights common side effects such as stomach upset and constipation, and offers practical strategies to reduce these effects, such as lower or alternate-day dosing and taking iron with vitamin C to enhance absorption. UK clinical guidance recommends confirming iron deficiency before long-term supplementation and consulting a GP for correct dosing, especially in pregnancy and chronic conditions.
Oral ferrous sulfate reliably raises haemoglobin and ferritin in people with iron deficiency when taken at appropriate doses.
Alternate-day dosing often improves absorption and reduces gastrointestinal side effects compared with daily high doses.
Taking iron with a vitamin C source enhances absorption; avoid taking with tea, coffee, dairy or calcium supplements close to the dose.
Common side effects include nausea, constipation or dark stools; these are dose dependent and may be managed by dose timing or formulation changes.
People with conditions such as haemochromatosis or those on certain medications should not self-prescribe iron and should seek medical advice.
