From December 13, 2026, it will become legally enforceable for certain breads, pasta, and baked goods sold in UK supermarkets to be made with wheat flour containing added folic acid. The measure, introduced under the revised Bread and Flour Regulations, is part of a Government-backed initiative to improve public health.
The legislation applies across all four nations, including Wales, Scotland, and Northern Ireland, as part of a joint four-nation public health initiative. Each devolved administration has brought forward its own aligned regulations, such as the Bread and Flour Amendment (Scotland) Regulations and the Bread and Flour (Wales) Regulations.
Why Folic Acid Is Being Added
The measure aims to reduce the number of cases of neural tube defects (NTDs), such as miscarriages, stillbirths, and spina bifida, occurring during pregnancy. NTDs are serious birth defects affecting the brain, spine, or spinal cord that typically develop very early in pregnancy, usually within the first four weeks.
Folic acid is the synthetic, man-made form of vitamin B9. Naturally occurring alternatives include foods rich in folate, such as dark leafy greens, certain fruits and vegetables, as well as sunflower seeds and flaxseed. Folic acid is entirely colourless, odourless, and flavourless, and is added in minuscule quantities.
Products Affected by the New Law
To determine whether a particular item contains fortified flour, consumers should check the ingredients list on the packaging. Under labelling regulations, folic acid must be listed alongside calcium, iron, niacin, and thiamin within the brackets following "Wheat Flour".
Affected products include standard white bread, half-and-half loaves, and regular brown bread, as well as certain crumpets, English muffins, bagels, croissants, and pancakes that use wheat flour. Bagged flour from major mills, including plain flour, self-raising flour, and strong white bread flour, will also be covered, along with baking mixes such as packet cake mixes, pancake mixes, scone mixes, and Yorkshire pudding mixes.
Biscuits including digestives, rich tea, custard creams, shortbread, and chocolate chip cookies are affected, as are cakes and pastries such as sponge cakes, muffins, doughnuts, fruit pies, and sausage rolls. Dried and fresh wheat pasta, spaghetti, and wheat-based noodles are included, along with sauces and thickeners such as gravy granules, packet sauces, and tinned or packet soups that use wheat flour as a thickening agent. Frozen and chilled savoury foods, including ready meals, battered or breaded fish and poultry, pies, pasties, and frozen pizzas, are also covered.
Exemptions and Consumer Impact
The law explicitly exempts specific flours and products. These include 100% wholemeal flour and breads or baked goods made entirely from wholemeal wheat flour, as well as foods made from rice, corn, oat, almond, buckwheat, or other gluten-free flours. Flours made from non-common wheat grains such as spelt, einkorn, and emmer are exempt, as is flour produced by small independent mills producing less than 500 metric tonnes per year. Imported finished baked goods or pasta are not covered, though imported bulk white flour used in the UK is.
Numerous fortified products are already available in UK supermarkets in advance of the legal December deadline. As mills and manufacturers update recipes and packaging at varying rates, shelves currently stock a mixture of fortified and unfortified products. From December 13 onwards, all newly manufactured non-wholemeal wheat flour products must be compliant.
Under UK regulations, millers add just 0.250 milligrams (250 micrograms) of folic acid per 100 grams of non-wholemeal wheat flour. This equates to approximately one-quarter of a grain of salt distributed across an entire bag of flour. The NHS recommends 200 micrograms of folate daily for adults, and consuming two slices of fortified toast delivers roughly half of that baseline daily requirement.
