Choose a post-gym snack bar by the specific ingredient or dietary characteristic you need to avoid, then check the current ingredients and any ‘may contain’ statement. Vegan and gluten-free describe different things: a bar can meet either description while containing soya, peanuts or milk. Once its label fits your needs, compare protein per whole bar rather than relying on a protein-bar name.
If you need to avoid peanuts, tree nuts, milk, soya or gluten-containing cereals, check the current ingredients and precautionary wording for that particular allergen. As Anaphylaxis UK explains, a ‘free from peanuts’ claim does not rule out other allergens.
A plant-based bar may suit your dietary preference while still containing or warning of other allergens. TREK Original Oat includes soya ingredients; the listed nākd. Protein Peanut Butter bar contains peanuts.
If you want a portable bar after training, compare its gluten-free declaration and protein per bar separately from its other ingredients. TREK Original Oat and Nature Valley Protein Peanut & Chocolate are described as gluten-free, but their other allergen profiles differ.
Start with the restriction that matters to you. Then compare serving information and pack format among bars whose current labels fit that requirement.
| Priority | What to check | Your needs |
|---|---|---|
| Specific allergens | Read the full ingredients list, highlighted allergens and any ‘may contain’ statement. Check the particular flavour and pack you will eat. | I need to avoid a named allergen, not just find a bar with a general free-from description. |
| Dietary claims | Check gluten-free, dairy-free and vegan claims separately. Compare each claim with the ingredients: gluten-free does not mean milk-free, and vegan does not mean soya-free. | A bar can fit one part of my diet without meeting every restriction I have. |
| Protein per bar | Compare the declared amount for one whole bar, not just per 100g or the wording on the front. TREK states 10g plant protein per Original Oat bar; Nature Valley states around 10g per 40g Peanut & Chocolate bar. | For a snack after training, I want to know what the portion I would actually eat provides. |
| Current recipe | Recheck the physical pack when a delivery arrives, including multipacks. Tesco Groceries warns that food ingredients, nutrition and allergen information can change. | Even if I have bought the same name before, I need the label on this pack to fit my requirements. |
Nature Valley Protein Peanut & Chocolate is described as gluten-free but lists peanut, soya and milk. TREK Original Oat is described as vegan and gluten-free but includes soya.
Match each ingredient and precautionary statement against what you need to avoid; do not use a vegan or gluten-free label as a substitute for that check.
According to Anaphylaxis UK, precautionary allergen labelling warns that an allergen might be present unintentionally. It is different from an allergen listed as an ingredient.
If you have a diagnosed allergy, assess the current statement in line with advice from your allergy clinician before eating the bar.
Protein figures are only useful for comparing the amount you intend to eat, and a bar with a suitable figure may still contain an allergen you avoid.
Compare protein per whole bar, then check its dietary claims and allergen information before deciding whether it works as your snack.
Ingredients and allergen declarations can change when food is reformulated, as Tesco Groceries notes in its product information.
Read the pack you receive before opening or serving a bar, even if you have eaten that product before.
These examples describe particular products or ranges, not an allergen profile shared by every bar from a brand.
