A measured portion of marshmallows is an option if you want carbohydrate shortly before exercise; a box of chocolates is not a predictable workout snack simply because it comes in a box. For a planned snack, University College London Hospitals NHS Foundation Trust advises including carbohydrate and protein with minimal fat, so check the individual product label rather than assuming either confectionery choice meets that description.
If you want a small carbohydrate portion before exercise, compare the amount you intend to eat with the carbohydrate and sugars shown on the pack. Marshmallows are a confectionery option, not a substitute for a planned snack containing protein.
Look beyond the marshmallow-versus-chocolate choice. University College London Hospitals NHS Foundation Trust advises that exercise snacks include carbohydrate and protein with minimal fat, alongside vitamins and minerals.
Compare exact variants rather than relying on the word “marshmallow”. Marks & Spencer lists beef gelatine in its Soft Marshmallows, while its Vegan Marshmallows carry separate milk, nut and peanut allergy cautions. ASDA’s Dandies listing identifies soya.
Start with when you plan to eat, then compare the portion and ingredients of the actual product. A gift-box format does not tell you whether its contents fit those checks.
| Priority | What to check | Your needs |
|---|---|---|
| Timing | Check the carbohydrate amount for the portion you would eat and how soon you plan to exercise. Do not treat a whole bag as one portion. | I only want a measured carbohydrate portion shortly before activity, rather than a full snack. |
| Planned snack | Look for carbohydrate and protein with minimal fat, as advised by University College London Hospitals NHS Foundation Trust. Check the full product label, not just the confectionery category. | There is a longer gap before my session, and I want to choose a snack with more than carbohydrate alone. |
| Portion and sugars | Compare sugars for the stated serving with the amount you intend to eat. Tesco lists 14.5 g sugars per 25 g of White Mini Marshmallows; ASDA lists 16 g per one-seventh of its 180 g marshmallow pack. | With a sharing bag or open chocolate box, I would rather decide on a portion before eating. |
| Ingredients | Read the exact variant’s ingredients, allergen information and suitability statement. Vegan labelling does not replace an allergy check. | I need to avoid particular ingredients, so the product name alone is not enough to make my choice. |
| Boxed chocolates | Check the individual assortment’s serving size, carbohydrate, fat and allergens before considering it as a snack. | I am choosing a gift or treat, but do not want to assume that its box says anything about its suitability before exercise. |
Tesco lists 1.4 g protein per 25 g of its White Mini Marshmallows. That portion alone does not match University College London Hospitals NHS Foundation Trust’s advice to include both carbohydrate and protein in an exercise snack.
If you need a planned snack rather than a small confectionery portion, compare foods that provide both nutrients.
Sugars are listed against a particular portion: Tesco gives 14.5 g per 25 g of White Mini Marshmallows, while ASDA gives 16 g per one-seventh of its 180 g pack. Those figures should not be compared as though the servings were identical.
Decide how much you intend to eat, then use the current pack’s per-serving or per-100 g figures to compare products on the same basis.
Marks & Spencer labels its Vegan Marshmallows as vegan but also says they are not suitable for people with milk, nut or peanut allergies. ASDA’s Dandies listing identifies soya.
Check the ingredients and allergy statement for the exact pack, even when its dietary label otherwise meets your needs.
These product examples show why portion information and ingredient checks matter; they do not indicate that every product from a retailer has the same recipe.
Tesco White Mini Marshmallows are a useful example of nutrition stated for a 25 g portion.
Marks & Spencer lists both standard Soft Marshmallows and a vegan variant.
ASDA lists an own-label marshmallow pack and Dandies Vegan Vanilla Flavoured Marshmallows.
Waitrose lists Pink and White Marshmallows in its confectionery range.
Sainsbury’s lists a 200 g pack of vanilla-and-raspberry-flavour marshmallows.
These marshmallow packs relate to the measured-portion choice before exercise, not the separate choice of a planned snack containing carbohydrate and protein. Check each pack’s nutrition and ingredients for the portion you intend to eat.

For a small marshmallow portion before exercise, compare the amount you intend to eat with the pack’s carbohydrate and sugars figures. Check its ingredients and allergen information if they affect your choice; marshmallows alone are not the planned snack described in the NHS guidance.

If choosing from this 200 g pack for a small portion before exercise, use the current nutrition label to work out the amount you would eat. Check the ingredient and suitability statements for any dietary restrictions; the pack is not a substitute for checking the protein in a planned snack.

This blueberry-flavoured 64 g pack is another marshmallow option for a measured portion. Read its current nutrition, ingredient and warning panels before choosing an amount, particularly if an ingredient or allergen affects your choice.
A measured portion can be a confectionery choice when you specifically want carbohydrate shortly before activity, but marshmallows alone are not a complete planned snack. University College London Hospitals NHS Foundation Trust advises including carbohydrate and protein with minimal fat in an exercise snack; Tesco lists 1.4 g protein per 25 g of its White Mini Marshmallows.
Choose by the individual product and the portion, not by whether it comes in a bag or gift box. Tesco’s White Mini Marshmallows have stated carbohydrate and fat figures for a 25 g serving, but you would need the particular chocolate assortment’s label to compare its serving size, carbohydrate, fat and allergens. Neither format alone establishes that it meets the NHS advice for a planned exercise snack.
Check the exact pack’s ingredients and allergy statement as well as its vegan label. Marks & Spencer labels its Vegan Marshmallows as vegan but says they are not suitable for people with milk, nut or peanut allergies; ASDA’s Dandies listing identifies soya.
