Compare calories and protein for the whole bar before choosing a pack: a low-sugar claim does not tell you its calorie total. Tesco Groceries lists TREK Choc Caramel at 159 kcal and 12g protein per 44g bar, while PhD Nutrition lists a Smart Bar at 250 kcal and 21g protein per 64g bar. The choice depends on whether keeping snack calories down or getting more protein from one bar matters more to you.
If you buy bars for work, travel or after exercise, check how many complete bars are in the pack. A 12-pack and a single bar also need to be compared by nutrition per bar, not by the figures printed for the whole pack.
The amount you eat matters as much as the front-of-pack description. Tesco Groceries lists 159 kcal and 12g protein for a 44g TREK Choc Caramel bar; PhD Nutrition lists 250 kcal and 21g protein for a 64g Smart Bar. Compare both values for a complete serving.
Look for a vegan statement on the exact product rather than relying on a plant-related name or a low-sugar claim. Tesco Groceries labels its TREK Choc Caramel bar suitable for vegans, and PhD Nutrition labels Smart Plant Vanilla Fudge vegan. Check the ingredients and allergen statement separately.
Start with the serving you intend to eat, then compare its protein and other label details. Check pack quantity and dietary suitability for the exact flavour you choose.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Find kcal for the complete bar, not just per 100g. Check the bar weight when comparing different sizes. | I want to know the energy value of the amount I will actually eat, especially when choosing between 44g, 50g, 60g and 64g bars. |
| Protein and sugar | Read protein and sugars per complete bar alongside kcal. Tesco Groceries lists 12g protein for the 44g TREK Choc Caramel bar; PhD Nutrition lists 21g for a 64g Smart Bar. | More protein in one bar may matter to me, but I do not want a low-sugar claim to stand in for a calorie check. |
| Pack quantity | Check the number of bars and each bar’s weight. Distinguish nutrition per bar from figures for a pack or per 100g. | For a budget shop, I want to know how many snacks a pack contains without mistaking a multipack figure for one serving. |
| Dietary suitability | Check the vegan statement, ingredients and allergen wording for the exact flavour and format. Read any on-pack polyol warning. | If I need a vegan bar or avoid an ingredient, the product label matters more than the range name; I also want to check warnings before buying several bars. |
A sugar claim does not establish the energy value of a complete bar. PhD Nutrition lists 250 kcal for a 64g Smart Bar even though it presents the range as low sugar.
Read kcal and protein per whole bar first. Check sugars as a separate figure if it matters to your choice.
A vegan label answers a different question from an allergen statement. Ingredients and precautionary allergen wording can also differ by flavour.
Read both statements on the exact bar you intend to buy, including when you change flavour or pack format.
PhD Nutrition warns that excessive consumption of its Smart Bar may cause laxative effects. That warning is relevant if you plan to eat the bars frequently.
Check the ingredients and any consumption warning on the chosen product before buying a multipack.
These examples show why a protein claim, a vegan label and a calorie figure need to be checked for the specific bar. They do not establish that every product in a brand’s range has the same nutrition.

Compare kcal for the complete bar with the amount you intend to eat; do not use a low-sugar claim as a substitute. For context, Tesco Groceries lists 159 kcal per 44g TREK Choc Caramel bar, while PhD Nutrition lists 250 kcal per 64g Smart Bar. The bars are different sizes and provide different amounts of protein, so read those figures together.
Read the ingredients and any on-pack consumption warning for that product. PhD Nutrition warns that excessive consumption of its Smart Bar may cause laxative effects; the warning should not be assumed to apply identically to every protein bar.
No. A vegan statement and an allergen statement address different requirements, so check the ingredients and precautionary wording for the exact flavour and pack. Tesco Groceries labels TREK Choc Caramel suitable for vegans, but that statement alone does not establish suitability for someone avoiding a particular allergen.
