People who count carbohydrates
If you count carbohydrates as part of your diabetes plan, the total for the portion you actually eat matters more than the sugars figure alone. Diabetes UK advises using total carbohydrate when counting carbs.
Who is this for?
Shoppers choosing an occasional bar
If you want a bar to carry between meals, compare its per-bar label and portion size before committing to a multipack. Energy and ingredients may also matter to your choice.
Flavour-trial buyers
A mixed box lets you try different flavours without buying a case of one. Check each wrapper before eating: the flavours, ingredients and allergens in an assortment need not be identical.
What should you check?
Start with the labelled portion and total carbohydrate, then decide whether a changing assortment, a fixed mix or a familiar single flavour fits the way you buy bars.
| Priority | What to check | Your needs |
|---|---|---|
| Total carbohydrate | Read total carbohydrate for the full bar or portion you will eat. Use per 100g figures to compare products on the same basis; do not substitute “of which sugars” for total carbohydrate. Diabetes UK makes this distinction in its carb-counting guidance. | I need to know how the bar I will actually eat fits my own carbohydrate plan, even when the front says “low sugar”. |
| Flavours and labels | Check whether the flavour list is fixed or variable, then read each wrapper’s nutrition and ingredients. Grenade says flavours in its 12-bar Selection Box can vary; Barebells names four flavours in its 12-pack. | I would like variety, but I need to check every included flavour rather than assume all the bars have the same label. |
| Allergens | Read the ingredients and highlighted allergens on each bar, particularly when buying an assortment. Do not rely on one flavour’s wrapper for the whole box. | If an ingredient or allergen matters to me, I need to confirm it for each flavour before eating. |
| Sweeteners and pack size | Review the ingredients and any consumption warning before buying several bars. Grenade’s Salted Caramel bar carries an excessive-consumption laxative warning; PhD’s Chocolate Brownie variant lists maltitols. | Before buying a larger single-flavour pack, I want to know whether I like that bar and how its ingredients suit me. |
Buying pitfalls
-
Choosing by sugars alone
PhD lists 1.2g sugars but 23g total carbohydrate per 64g Chocolate Brownie Smart Bar. Those figures answer different label questions.
Check total carbohydrate for the portion you intend to eat first; use the sugars figure as additional information, not a substitute.
-
Assuming every bar in a box is alike
Grenade says the flavours in its Selection Box can vary. An assortment therefore calls for a wrapper-by-wrapper check of carbohydrate, ingredients and allergens.
Review the included bars before treating a mixed box as a regular snack supply.
-
Buying a case before trying its sweeteners
Some bars containing maltitol carry an excessive-consumption laxative warning; the warning for Grenade’s Salted Caramel bar should not be assumed to describe every Grenade flavour.
Read the warning on the specific bar and consider trying that flavour before choosing a larger pack.
-
Treating a protein bar as a hypo remedy
A protein bar should not replace the fast-acting carbohydrate in a hypo treatment plan. Diabetes UK’s guidance describes treating a hypo immediately with fast-acting carbohydrate.
Keep to your established hypo plan rather than relying on a low-sugar snack bar for that purpose.
Brand and retailer references
Grenade
Grenade describes its Protein Bar Selection Box as a 12-bar variety box whose flavours may vary.
- A mixed box provides a way to try flavours.
- Check each included wrapper for its carbohydrate and allergens; Grenade’s Salted Caramel bar also carries an excessive-consumption warning.
Barebells
Barebells lists Salty Peanut, Hazelnut & Nougat, Caramel Cashew and Cookies & Cream in its 12-pack Selection Box.
- Named flavours make it possible to plan which individual labels to check.
- Do not use one flavour’s nutrition figures for the others; check each bar’s total carbohydrate.
PhD
PhD’s Smart Protein Bar 12-pack is a single-flavour option rather than a mixed grab bag.
- PhD lists 23g carbohydrate, 1.2g sugars and 21g protein per 64g Chocolate Brownie bar.
- Those figures apply to Chocolate Brownie, not every flavour. Its ingredients include maltitols.
Quest
Quest Nutrition describes a protein-bar variety pack on its US storefront.
- The US pack is presented as a mixed-flavour format.
- For a UK purchase, check the seller and the labels of the actual bars rather than assuming the US pack’s details apply.
Tesco Groceries
Tesco Groceries lists a Grenade Fan Favourites Selection Box containing 10 × 60g bars, as well as individual bars and smaller multipacks.
- Different pack sizes offer a way to compare how many bars you want to buy.
- Check the current listing and the individual bar labels for the assortment you choose.
Joybuy protein-bar options
These Joybuy options are single-flavour Grenade multipacks, not mixed-flavour grab bags. A four-bar pack offers a smaller flavour trial; consider a 12-bar pack once you have checked the specific bar’s label.

Grenade Oreo protein bars, 4 × 60g
A four-bar pack to consider if you want to try the Oreo flavour before buying more. Check the total carbohydrate, ingredients and allergens on the bars you receive.
No image available
Grenade Jaffa Quake protein bars, 12 × 60g
A single-flavour 12-pack for shoppers considering Jaffa Quake in quantity. Check that flavour’s per-bar total carbohydrate, ingredients and allergens before choosing the case.

Grenade Oreo protein bars, 12 × 60g
The larger Oreo pack is a different commitment from the four-bar option above. Compare the specific bar’s total carbohydrate and ingredients with your needs before buying twelve.

Grenade Soft Core Double Chocolate, 12 × 50g
This pack contains 50g bars. When comparing it with a 60g-bar pack, use both the per-bar carbohydrate figure for your intended portion and the per 100g figure for a like-for-like label comparison.

Grenade Soft Core Golden Caramel, 12 × 50g
Another single-flavour pack of 50g bars. Check Golden Caramel’s own wrapper for total carbohydrate, ingredients and allergens rather than applying figures from Double Chocolate or another Grenade bar.
Questions about choosing bars
Does “low sugar” mean a protein bar fits a diabetes plan?
No. Diabetes UK advises checking total carbohydrate, not just sugars. Compare the total for the portion you will eat with your own plan; a front-of-pack sugar claim does not answer that question.
Which figure matters when I count carbohydrates?
Use total carbohydrate for the bar or portion you intend to eat, rather than the “of which sugars” figure. Diabetes UK explains that carbohydrate counting uses total carbs; follow the individual approach agreed with your diabetes care team.
Can I use a low-sugar protein bar to treat a hypo?
Do not rely on it as a replacement for your hypo treatment. Diabetes UK describes immediate treatment with fast-acting carbohydrate; keep to the treatment plan given to you by your care team.
How do I check a mixed box for allergens?
Read the ingredients and highlighted allergens on each individual wrapper before eating that flavour. This matters especially for a variable assortment such as Grenade’s Selection Box: one bar’s label cannot stand in for every bar in the box.
