Gym-goers carrying a gluten-free snack
A portionable biscuit can fit in a gym bag before a session or between meals. Look for an explicit gluten-free label rather than assuming an oat biscuit meets your requirements.
Who is this for?
People with coeliac disease who eat gluten-free oats
Check the exact biscuit's gluten-free claim, oat ingredients and allergen statement. Coeliac UK says most people with coeliac disease can eat gluten-free oats, but a small number remain sensitive to oats.
Shoppers also avoiding milk or animal-derived ingredients
Gluten-free does not mean milk-free or vegan. Tesco lists its Free From Digestives as milk-free and suitable for vegans; check the current pack for the combination you need.
What should you check?
Start with the gluten-free claim and any other ingredients you need to avoid, then compare the biscuit format and nutrition for when you plan to eat it.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free status | Look for an explicit gluten-free claim, including on oat-based biscuits. The Food Standards Agency states that food labelled gluten-free must contain no more than 20 mg/kg of gluten as sold. | I need a biscuit labelled gluten-free, not simply one made with oats. |
| Gym-bag use | Check the pack format and nutrition per biscuit so you can plan a portion. Tesco lists 7.2g carbohydrate per 12g Free From Digestive. | A small, portionable snack would suit me before a session or between meals. After intense or prolonged exercise, I would account separately for the protein and fluids in UK Sports Institute recovery guidance. |
| Other ingredients | Read the current oat, milk and nut information. Tesco warns that its Free From Digestives may contain peanuts and nuts; Sainsbury's says its Free From Digestives are unsuitable for customers with a nut allergy because of manufacturing methods. | My gluten-free choice must also fit any other ingredients I avoid. If oats are an issue for me, I need to check the exact biscuit rather than rely on its gluten-free label alone. |
| Nutrition and format | Compare figures on the same basis, such as per biscuit or per 100g, and distinguish a digestive from another oat biscuit. Tesco lists 56 kcal and 0.8g fibre per Free From Digestive; Nairn's lists 48 kcal and 0.7g fibre per Gluten Free Oatie. | If the digestive texture matters to me, an oat-biscuit alternative is a different choice. I want the portion and nutrition figures for the biscuit I will actually pack. |
Common buying mistakes
-
Assuming oats automatically mean gluten-free
Coeliac UK notes that ordinary oats can be contaminated when produced alongside wheat, barley or rye. Some people are also sensitive to oats that are gluten-free.
Choose a biscuit explicitly labelled gluten-free, then check its current ingredients and allergen statement.
-
Relying on a biscuit as a complete recovery snack
Tesco lists 0.8g protein per Free From Digestive. UK Sports Institute guidance describes a carbohydrate- and protein-containing snack with fluids after intense or prolonged exercise.
Consider the biscuit as one part of what you carry, rather than assuming it covers every post-exercise need.
-
Treating gluten-free as an all-allergen claim
A gluten-free digestive can still carry a nut warning, and milk or vegan suitability differs between products.
Read the declaration on the exact pack, particularly if you also avoid nuts, milk or oats.

Frequently asked questions
Are oat-based digestives automatically gluten-free?
No. Coeliac UK explains that ordinary oats can be contaminated during production alongside wheat, barley or rye. Choose a biscuit explicitly labelled gluten-free and check its current ingredients; Coeliac UK also notes that a small number of people are sensitive even to gluten-free oats.
Can I pack a gluten-free digestive for before the gym?
A portionable digestive can be a convenient carbohydrate-containing snack. Tesco lists 7.2g carbohydrate per 12g Free From Digestive; use the serving information on your chosen pack when deciding how much to carry and when it fits your session.
Is a digestive enough after an intense workout?
Do not assume a biscuit alone covers recovery after intense or prolonged exercise. UK Sports Institute guidance describes a carbohydrate- and protein-containing snack with fluids, followed by a meal; Tesco lists 0.8g protein per Free From Digestive.
Do England's HFSS promotion rules restrict what I put in my gym bag?
No. Department of Health and Social Care guidance describes restrictions on certain promotions and placements by qualifying retailers selling in England, not an individual's choice of gym-bag snack. Those rules do not establish whether a particular biscuit is classified as high in fat, salt or sugar.
