The best price per 14 mg iron and per month across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing iron

We count the iron a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Iron comes as bisglycinate (gentle iron), fumarate, sulphate, gluconate and other forms, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine iron with other ingredients are listed separately, because their price buys more than iron. 14 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Prices last checked: 20 October 2026. Ranked purely by price per 14 mg iron — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

By shop

Each shop's iron products, with where its cheapest sits in the market.

How we work out these prices

We count the elemental iron a product provides, not the weight of the whole compound it comes in. If a label states the iron amount, we use it. If it only gives the compound's weight, we estimate using a published conversion factor and mark the figure “estimated”. If we cannot tell which the number means, the product is left out until it can be confirmed.

Conversion factor used when only the compound weight is given: sulfate 20.1%. How we chose these.
