Is wholemeal flour fortified with folic acid?
Updated 23 October 2026. Every claim links to its source.
No. In the UK, wholemeal flour is exempt from the rules that make millers add nutrients to flour. From 13 December 2026 those rules add folic acid to the existing calcium, iron, niacin and thiamin, but they only cover non-wholemeal flour milled from common wheat (GOV.UK; Bread and Flour Regulations 1998, reg. 4).
What the law says
Regulation 4 says the fortification requirements "shall not apply to (a) wholemeal flour" or to flour from a small mill (reg. 4(1A)). The same regulation defines wholemeal flour as "the flour consisting of the whole of the product obtained from the milling or grinding of cleaned cereals" (reg. 2). Government guidance explains this as the entire edible grain, including the germ, endosperm and bran, after inedible parts such as the hull are removed (GOV.UK).
These versions of the rules cover England and Scotland. Wales now has its own Bread and Flour (Wales) Regulations 2025, and Northern Ireland has separate regulations. The joint UK-wide government guidance describes the same wholemeal exemption for all of them (GOV.UK).
Wholemeal, brown and "50/50" are not the same
- 100% wholemeal flour is the whole milled grain, so it is exempt.
- Brown, "wheatmeal", malted or seeded blends are not legally defined terms (GOV.UK). If part of the flour is non-wholemeal common wheat flour from a large mill, that part must be fortified. Check the ingredients list.
- Bread: a loaf can only be named "wholemeal" if all the flour in it is wholemeal. A white and wholemeal mix must not be called wholemeal bread (GOV.UK). "Brown" and "half and half" loaves usually contain some white flour.
How to check the label
Added vitamins and minerals must appear in the ingredients list, including when fortified flour is used as an ingredient in another food (GOV.UK). Government guidance gives this example of what fortified flour looks like on a label: "Wheat Flour (Wheat Flour, Calcium Carbonate, Folic Acid, Iron, Niacin, Thiamin)". If you see "folic acid" or the other added nutrients, the product contains fortified flour.
Plain "wholemeal wheat flour" with nothing else listed should be unfortified. Doves Farm, for example, says its wholemeal wheat flours are exempt and will not contain folic acid (Doves Farm FAQ). Doves Farm also warns that until the end of 2026 some products "may or may not yet contain folic acid" while stock changes over, and government guidance lets flour labelled or placed on the market before 13 December 2026 stay on sale (Doves Farm FAQ; GOV.UK). Read the bag, not just the brand.
Other flours that are outside the rules
The fortification rules only cover common wheat (Triticum aestivum) (reg. 2; GOV.UK). Doves Farm says spelt, einkorn, emmer and rice flours are not covered (Doves Farm FAQ). If you want white flour without added folic acid, it has to come from a small exempt mill. See our guide to where to buy unfortified flour.
