What should you check before buying?
Decide whether an exact digestive matters, then check the gluten-free label, other allergens and the portion you intend to serve.
| Priority | What to check | Your needs |
| Gluten-free labelling |
Check the current pack for a gluten-free claim. Food Standards Agency guidance sets a maximum of 20 mg/kg of gluten in food sold with that label; Coeliac UK says its Crossed Grain Trademark involves additional checks. |
I need a clearly labelled option for strict gluten avoidance. In Coeliac UK’s 2025 survey of 3,785 members, 74.7% trusted its Crossed Grain Trademark more than a gluten-free statement. |
| Other allergens |
Read the full ingredients and allergen statement, including cross-contact warnings. Check oats and any avenin warning separately when considering an oat biscuit. |
If the child also avoids milk, soya or another ingredient, a gluten-free claim alone does not settle whether I can serve the biscuit. |
| Biscuit type |
Distinguish a plain gluten-free digestive from a chocolate-coated digestive or an oat-biscuit alternative. Check the exact product name and current pack. |
I want a familiar digestive rather than a different biscuit; or I am happy to change format for a snack to take out. |
| Portions and nutrition |
Look at biscuits per pack or pouch and the stated serving size. Compare sugar and saturates using the same nutrition basis, such as per 100g. |
A defined portion would help me pack snacks, or I would rather compare a chocolate option with a plain one before choosing. |
| Where it will be served |
For a school-provided snack or meal, check the school or caterer’s requirements separately from the biscuit’s gluten-free label. |
I am buying for a home half-term snack, or I need to confirm the arrangements before sending food to school. |
Relevant biscuit brands and ranges
These references distinguish exact gluten-free digestives from other biscuit formats; a brand name alone does not establish that every product in its range meets the same needs.
Schär
Its Digestive Biscuits are a plain digestive-style option labelled gluten- and wheat-free.
- Schär’s UK product description also lists lactose-free and vegan claims for these biscuits.
- Check the current pack for soya and possible lupin or egg warnings if these matter to the child.
Tesco Free From
Tesco lists a 160g gluten-free digestive made with gluten-free oat flour.
- It offers an own-label route to the traditional digestive format.
- Tesco’s listing gives 55 kcal per biscuit and marks fat and saturates as high per biscuit; check the current pack for ingredients, allergens and nutrition information.
Nairn’s
Gluten Free Oaties are an oat-biscuit alternative rather than an exact digestive.
- Ocado lists this product in four pouches of four biscuits.
- It contains oats, may contain milk and is labelled unsuitable for people who react to avenin. Check the warnings on the particular Nairn’s product chosen.
Prewett’s
Its gluten-free milk chocolate digestives offer a chocolate-coated version of the digestive format.
- Waitrose & Partners describes the biscuits as half coated in milk chocolate.
- They contain milk and carry a nut warning. The retailer lists 28.9 g sugars and 11.3 g saturates per 100g.
M&S Made Without
Its free-from biscuit range is worth considering when an exact digestive is not essential.
- M&S lists options including Made Without Wheat and Gluten Fruity Flapjack Cookies and Made Without Wheat Stem Ginger Snaps.
- Check the specific biscuit’s current pack rather than treating the wider range as a digestive substitute.
McVitie’s
Original Digestives are a conventional digestive reference, not the gluten-free option described here.
- The Waitrose & Partners listing identifies the Original product as wheatmeal biscuits.
- Do not choose Original Digestives for a gluten-free requirement. Check a separately labelled product’s own pack if considering another McVitie’s biscuit.

Questions about gluten-free biscuits
What does gluten-free mean on a biscuit label?
Food Standards Agency guidance says food labelled gluten-free must contain no more than 20 mg/kg of gluten as sold to the final consumer. It does not mean the biscuit is free from milk, nuts, soya, eggs, lupin or oats, so check the current ingredients and allergen statement too.
Does a gluten-free digestive need the Crossed Grain Trademark?
No. The gluten-free labelling threshold does not require that trademark. Coeliac UK says products carrying its Crossed Grain mark undergo additional checks, including review of gluten analysis certificates and independent manufacturing audits.
Is a gluten-free oat biscuit suitable for everyone avoiding gluten?
No. Nairn’s Gluten Free Oaties are described as suitable for coeliacs, but the product warning says they are not suitable for people who react to avenin, a protein in oats. Check the warning on the particular biscuit’s current pack.
Does the name digestive mean the biscuit aids digestion?
No. Waitrose & Partners’ Schär listing says digestive is a traditional British biscuit name and does not mean the biscuit aids digestion.
Can I assume a gluten-free digestive is suitable for a school snack?
No. A gluten-free label concerns gluten, not a school’s arrangements for food and allergens. Department for Education school-food guidance addresses food provided in state-funded schools in England; ask the particular school or caterer about a biscuit intended for a school snack or meal.
