Best Ferrous Sulfate Tablets UK 2026 — Top 5 Iron Supplements
Ferrous sulfate tablets are a convenient and effective way to supplement iron in the diet and are commonly used in the UK to treat or prevent iron deficiency anemia. Popular with people managing heavy menstrual loss, pregnancy-related needs, vegetarian or vegan diets, and general low iron levels, ferrous sulfate is favored for its high elemental iron content, wide availability and low cost. UK consumers often choose products based on strength, tolerability, dosing frequency, brand trust and format, which is why the market includes high-strength tablets, lower-dose maintenance formulas and gentler liquid options. Guidance from the NHS and UK clinicians encourages appropriate dosing and medical review, while shoppers look for clear labeling, reputable retailers such as Boots and Holland & Barrett, and options that reduce common gastrointestinal side effects.

Top Picks Summary
Ferrograd Tablets 325mg
Ferrograd 325mg positions itself as the high-strength ferrous sulfate option in this list, favored for delivering a larger iron salt dose per tablet which can reduce pill burden for those with moderate to severe deficiency. Compared with lower-dose options like Boots 200mg and Holland & Barrett 14mg, Ferrograd aims to be the cost-effective choice for rapid repletion, while its tablet form typically offers simpler storage and dosing than liquid alternatives such as Spatone.
Galfer Capsules 305mg
Galfer 305mg capsules are a ferrous fumarate iron supplement — a different iron salt to the ferrous sulfate in Ferrograd or Boots — providing about 100 mg of elemental iron per capsule. The capsule format can be easier to swallow than coated tablets, and Galfer is a common, reasonably priced choice for treating iron deficiency where a higher single-dose iron supplement is wanted over low-dose maintenance products like Holland & Barrett 14mg.

Boots Iron 200mg is the mainstream high-street, value-oriented choice that trades off peak potency for broad availability and affordability, making it a practical first-line option for many consumers. Compared with premium or specialty items (Ferrograd and Galfer), Boots combines retail convenience and competitive pricing, while it sits above low-dose maintenance supplements and offers a simpler alternative to liquid products like Spatone for those who prefer tablets.

Spatone Liquid Iron Supplement
Spatone offers a liquid natural iron concentrate rather than a ferrous sulfate tablet, and it is included here as the gentler, better-tolerated alternative for people who experience gastrointestinal side effects from ferrous salts. While Spatone typically provides lower elemental iron per dose and commands a higher per-serving price than tablet-form ferrous sulfate brands, its technical advantage is tolerability and suitability for sensitive users or those who prefer single-dose liquid administration.
Holland & Barrett Iron 14mg Tablets
Holland & Barrett 14mg tablets are positioned as a low-dose, maintenance-focused iron supplement aimed at daily prevention or mild deficiency management, offering an economical option for long-term use. Compared with high-strength therapeutic products like Ferrograd or Galfer, this product reduces risk of gastrointestinal intolerance and is financially attractive for routine supplementation, though it is not intended for rapid repletion where higher-dose ferrous sulfate tablets would be more effective.
