Allergen Free Supplements

The 14 allergens UK law makes you declare

UK food law names 14 allergens that must be declared on a label: cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, nuts, celery, mustard, sesame, sulphur dioxide and sulphites, lupin and molluscs. Food supplements follow the same labelling rules as food. Products in this collection use none of those 14 as an ingredient, which is why you will find capsules, tablets, powders and liquids here rather than one single format. If you need to combine requirements, our supplements by diet pages let you filter further.

The allergen is rarely the nutrient itself

Magnesium, vitamin C and B12 are not allergens. The risk sits in the ingredients around them. Lactose from milk is a common tablet filler. Soya lecithin turns up in softgels. Starch used as a binder can come from wheat. Sulphites act as a preservative in some plant extracts, and fish oil is, of course, fish. So the "other ingredients" line on the back tells you more than the claims on the front. A gelatine-free capsule made from HPMC, a plant-based film, avoids animal gelatine and the lactose that often travels with it.

Powders and liquids widen the options

Tablets need binders, flow agents and coatings, so they carry the longest ingredients list. Powders and drops need fewer helpers, which is why several of the strictest products here are unflavoured powders or plain oils. The trade-off is practical: a powder means measuring a scoop, and many liquids need refrigeration once opened. Flavoured powders raise their own question, because some natural flavours are carried on maltodextrin or lecithin. We check that carrier before a product goes live.

How we choose the products on this page

We normally judge a supplement on three things: the form, the dose and the combination. Here we add a fourth, the full list of other ingredients. We prefer HPMC plant capsules to gelatine, algae oil to fish oil for omega-3, and rice or acacia fibre to wheat-derived starch as a filler. We turn down products that get the dose right but carry a broad precautionary warning the brand cannot explain to us. We buy directly from brands, our compliance team checks every label, and independent labs spot-check batches. You can read how we select brands and products.

Who this selection suits, and what it cannot promise

This page is for you if you have a diagnosed food allergy or coeliac disease, if you are buying for a child with several allergies, or if you simply want a shorter ingredients list. Be clear with yourself about the certainty you need. An ingredients list tells you what was added on purpose. It does not tell you what a shared production line may have left behind, and precautionary "may contain" labelling in the UK is voluntary rather than required.

• Named exclusions on every product page, so you can see which of the 14 are ruled out.
• Precautionary notes kept visible where a brand states them, instead of hidden.
• One new product at a time is the sensible way to start if your reactions are severe.

Many of our vegan supplements fit here too, but vegan on its own still allows soya, wheat and sesame, so the two labels are not interchangeable.
