Choose a labelled sugar-free gummy if you want a handheld, chewy sweet during revision; choose sugar-free jelly pots or crystals if a spoonable dessert fits the break better. Check the exact ingredients before buying: the Tesco-listed Diablo gummies contain gelatine and the sweeteners maltitol and sorbitol, while Joybuy’s Hartley’s strawberry crystals contain pork gelatine and aspartame. “Sugar-free” describes a sugar limit, not whether a product meets every dietary need.
If a chewy desk snack is the aim, distinguish jelly sweets from spoonable jelly desserts. For a sugar-free claim, UK legislation sets a limit of no more than 0.5 g of sugars per 100 g or 100 ml; check the claim and nutrition declaration on the product you choose.
Jelly texture does not establish ingredient suitability. Tesco lists gelatine in Diablo Sugar Free Gummy Bears, while Joybuy lists pork gelatine in Hartley’s Strawberry Jelly Sugar Free crystals. Check the exact variant rather than assuming that all products from a brand use the same ingredients.
Diablo’s listed ingredients include maltitol and sorbitol. Norfolk and Norwich University Hospitals NHS Foundation Trust advises avoiding sugar-free sweets containing sorbitol, mannitol or xylitol in its guidance for people with diarrhoea. The ingredient list matters more than the front-of-pack sugar claim for this check.
Decide whether the revision break calls for a chewy sweet, a ready-to-eat dessert or jelly prepared in advance. Then check the sugar declaration and the ingredients of that particular product.
Choose when: You want a handheld gummy rather than a dessert; Tesco describes Diablo Sugar Free Gummy Bears as jelly sweets with sweeteners.
Trade-off: The listed gummies contain gelatine, maltitol and sorbitol, so their ingredients need checking against your dietary requirements.
Choose when: A spoonable pot or jelly made ahead of the break suits you better than a chewy sweet.
Trade-off: Crystals require preparation and setting, and ingredients differ between variants; Joybuy’s Hartley’s strawberry crystals contain pork gelatine and aspartame.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Check the sugar-free claim and sugars in the nutrition declaration. UK legislation permits the claim at no more than 0.5 g of sugars per 100 g or 100 ml; for crystals, note whether figures describe the prepared jelly. | I want the product to meet the sugar-free criterion, rather than relying on “no added sugar” or lighter-sounding packaging. In a Food Standards Agency and Ipsos survey of 611 people in Northern Ireland, conducted from September to November 2024, 49% said they actively used traffic-light labelling when shopping for food; that figure is about food-label use, not demand for these sweets. |
| Sweeteners | Read the ingredient list for polyols such as sorbitol and any pack warning. Tesco lists maltitol and sorbitol in Diablo Sugar Free Gummy Bears. | For a longer revision session, I want to know which sweeteners are in the pack before choosing a gummy. Norfolk and Norwich University Hospitals NHS Foundation Trust specifically discusses sorbitol-containing sugar-free sweets in its diarrhoea guidance. |
| Dietary ingredients | Check the gelatine source and suitability statement. For products containing aspartame, check the phenylalanine declaration if phenylketonuria (PKU) is relevant. | A jelly texture tells me nothing about whether a product is vegetarian, vegan or pork-free. Joybuy lists pork gelatine, aspartame and a phenylalanine-source declaration for Hartley’s strawberry crystals. |
| Snack format | Distinguish handheld gummies, ready-to-eat pots and crystals that need making and setting. Check the format and pack configuration of the exact item. | I may want a sweet that is ready at my desk, or I may have time to prepare a spoonable jelly for a later break. A dessert jelly will not provide the same chewy texture as a gummy. |
A sugar-free jelly pot or packet of crystals is a different format from chewy confectionery. Crystals also need making before they can be eaten.
Choose the format first: handheld gummy, ready-to-eat pot or crystals to prepare ahead of time.
Tesco lists maltitol and sorbitol in Diablo Sugar Free Gummy Bears. Norfolk and Norwich University Hospitals NHS Foundation Trust names sorbitol among the ingredients to avoid in sugar-free sweets in its diarrhoea guidance.
Read the ingredient list and any warning on the exact pack, particularly if polyol ingredients matter to you.
The listed Diablo gummies contain gelatine, and Joybuy’s Hartley’s strawberry crystals contain pork gelatine. The Hartley’s listing also declares aspartame and a source of phenylalanine.
Check the exact product’s ingredients and suitability statement for vegetarian, vegan, pork-free or PKU-related requirements.
England’s Requirements for School Food Regulations 2014 define non-chocolate confectionery as confectionery whether or not it contains sugar. The Department for Education describes its school-food guidance as applying to food and drink provided in state-funded schools; that setting is different from an ordinary personal revision snack.
If a snack is being provided through a school-food service in England, check the rules and the school’s arrangements for that setting rather than treating a sugar-free label as an exemption.
These references distinguish chewy sweets from dessert jelly and identify ingredients worth checking; they do not mean every product from a named brand is sugar-free.
Tesco Marketplace lists Diablo Sugar Free Gummy Bears as teddy-bear-shaped jelly sweets with sweeteners.
Tesco and Sainsbury’s list Hartley’s sugar-free jelly in dessert formats, including pots, multipacks or crystals.
Tesco lists Haribo jelly and chewy sweets, including Goldbears and Starmix, as conventional sweet options.
Tesco lists Rowntree’s products such as Randoms, Fruit Gums, Fruit Pastilles and Jelly Tots among its jelly and chewy sweets.
Tesco lists conventional jelly sweets, a sugar-free jelly-dessert category and Diablo gummies through Tesco Marketplace.
This Joybuy option is a sugar-free jelly dessert to make ahead for a revision break, not a ready-to-eat chewy sweet.

These crystals suit a revision break when you can prepare the jelly with boiling water and leave it to set; they are not a handheld gummy. Joybuy lists 0.5 g sugars per 100 g as prepared, along with pork gelatine, aspartame and a source-of-phenylalanine declaration. Check the pack if any of those ingredients affect your choice.
No. Under the UK sugar-free nutrition-claim rule, legislation permits the claim when a food contains no more than 0.5 g of sugars per 100 g or 100 ml. The claim does not tell you whether the product contains sweeteners or meets other dietary requirements.
Read the exact sweet’s ingredient list: Tesco lists maltitol and sorbitol in Diablo Sugar Free Gummy Bears. Norfolk and Norwich University Hospitals NHS Foundation Trust advises avoiding sugar-free sweets containing sorbitol, mannitol or xylitol in its diarrhoea guidance.
Not necessarily. Tesco states that the listed Diablo gummies contain gelatine and are not suitable for vegetarians or vegans; Joybuy lists pork gelatine in Hartley’s strawberry crystals. Check the ingredients and suitability statement on the exact product.
A sugar-free claim does not itself exempt a sweet from school-food rules. England’s Requirements for School Food Regulations 2014 include non-chocolate confectionery whether or not it contains sugar in their definition of confectionery. For food provided through a school service, check the current rules and arrangements that apply to that school; this is a different question from choosing a personal revision snack.
No: a pot is spoonable, and crystals need preparing and setting, whereas a gummy is a handheld chewy sweet. Choose the format that fits your break, then check that particular product’s sugar declaration and ingredients.
