Choose by the allergen you need to avoid before choosing between a single slice and a biscuit pack. The checked individually wrapped McVitie’s caramel digestive slice contains wheat, milk and soya ingredients; the checked Tesco, Sainsbury’s and Asda free-from digestives are oat-based packs with different precautionary warnings. None is suitable for every allergy, so check the current pack against your requirements before eating.
A single portion may be convenient to take out, but its ingredients and precautionary warnings still determine whether it fits a particular allergy. Tesco lists one wrapped McVitie’s caramel slice; Sainsbury’s lists individually wrapped slices sold together in a five-pack.
A multi-biscuit pack may work when a single portion is less important. The checked Tesco, Sainsbury’s and Asda free-from digestives use oats and have differing nut or peanut warnings, so each pack needs its own assessment.
Conventional biscuits are a separate choice from caramel slices and free-from packs. McVitie’s Original lists wheat and says it may contain milk; the checked M&S Digestive Biscuits list wheat and barley malt extract.
Start with the exact product’s current allergen information, then decide whether you need one separately sold slice, individually wrapped portions in a multipack or an ordinary biscuit packet.
| Priority | What to check | Your needs |
|---|---|---|
| Specific allergens | Read the current pack’s ingredients and relevant precautionary statements. Check the exact product and pack format rather than applying one digestive biscuit’s warning to another. | I need to know whether this particular snack lists an ingredient or cross-contact warning relevant to my allergy before its format matters. |
| Pack format | Tesco lists a 51.5 g McVitie’s caramel slice as one individually wrapped portion. Sainsbury’s lists five individually wrapped slices together; the checked free-from digestives are 188 g biscuit packs. | Am I buying one wrapped slice, several wrapped portions in one pack, or biscuits to keep after opening? |
| Free-from claims | Match each claim to the allergen it names. The checked Tesco, Sainsbury’s and Asda free-from digestives use oats and carry different nut or peanut statements. The Food Standards Agency identifies oats as an allergen even when they are gluten-free. | Gluten-free or milk-free wording addresses one requirement, but I still need to check oats and any other allergens relevant to me. |
The checked gluten- and milk-free digestives use oats. Tesco lists a possible presence of peanuts and nuts, Sainsbury’s warns that its product is not suitable for customers with a nut allergy due to manufacturing methods, and Asda lists a possible presence of nuts.
Match the claim, ingredients and warning on the current pack to the allergen you need to avoid.
McVitie’s caramel digestive slice contains wheat, milk and soya ingredients. Tesco’s single-slice listing also says it may contain peanuts, nuts and egg.
Assess the slice’s own label before choosing it for its individually wrapped format.
McVitie’s general caramel-slice information says the product may contain egg, while Tesco’s listing for a single 51.5 g slice additionally mentions peanuts and nuts. Those statements should not be treated as interchangeable.
Use the warning on the exact pack you receive and ask the retailer or manufacturer for product-specific clarification if it is unclear.
The checked products include plain Original digestives and caramel digestive slices, including a separately sold wrapped slice and wrapped slices in a multipack.
Tesco lists Free From Digestives made with gluten-free oat flour in a 188 g pack.
Sainsbury’s lists oat-based Free From Digestive Biscuits in a 188 g pack.
Free From by Asda Digestive Biscuits are a 188 g oat-based pack labelled gluten-free and milk-free.
The checked M&S Digestive Biscuits are conventional biscuits in a 400 g packet, rather than a wrapped single slice.
These Joybuy options are 150 g biscuit packs, not single wrapped slices. Schar is labelled digestive biscuits; McVitie’s Gluten Free Hobnobs are a different biscuit, so check the product type as well as the allergens before choosing.

A 150 g pack to consider if you want digestive biscuits rather than a single wrapped slice. Check the current pack’s ingredients and precautionary warnings against your particular allergens, including soya and lupin.

A 150 g gluten-free biscuit pack, but Hobnobs are not digestives or single wrapped slices. If oats, milk, nuts, egg or soya matter to your choice, check the current pack’s ingredients and precautionary warnings.
No. The checked Tesco, Sainsbury’s and Asda free-from digestives use oats. The Food Standards Agency says oats remain an allergen even when they are gluten-free, so assess an oat allergy separately from a need to avoid gluten.
No. Vegan labelling alone does not replace the product’s allergen information or address every cross-contact risk. Check the current ingredients and relevant precautionary statements for the exact biscuit.
No. Tesco lists one 51.5 g wrapped McVitie’s caramel slice, while Sainsbury’s lists five individually wrapped slices sold together. Check the number of slices in the retail pack before ordering.
Use the delivered pack’s label when assessing the product, rather than assuming the online description still applies. If the ingredients or warnings are unclear for your allergy, seek clarification from the retailer or manufacturer before eating it.
For food prepacked on-site for direct sale, Food Standards Scotland says UK rules in force since 1 October 2021 require the food name and a full ingredients list, with regulated allergenic ingredients emphasised. That labelling requirement does not establish whether a particular snack suits an individual allergy.
