The RXBAR Blueberry Bar is a whole-food protein bar built on a short, recognisable ingredient list: egg whites, dates, almonds, cashews, and real blueberries. There is no long tail of additives or fillers — what you see on the front is what you get inside. The protein comes from egg whites, which provide a complete amino acid profile without the dairy that whey-based bars rely on. Dates act as the natural binder and primary source of sweetness, keeping added sugar out of the picture. Almonds and cashews contribute healthy fats and a satisfying density that helps the bar hold you over between meals.
This bar suits anyone who wants something convenient that still reads like food rather than a formulation. It works well as a mid-morning snack, a desk lunch gap-filler, or a post-training bite when you want protein without a shake. The blueberry flavour is derived from actual blueberries, not flavouring, which is a small but meaningful distinction in a category where that is not always the case.
RXBAR built its reputation on ingredient transparency at a time when most bars buried the real contents in small print. The format — leading with the ingredient list — reflects a straightforward philosophy that aligns with how our team thinks about everyday nutrition: fewer, better ingredients, chosen for what they actually contribute.
Egg whites, Dates, Almonds, Cashews, Blueberries

Eat one bar as a snack between meals, post-training, or whenever you need a quick protein hit. No preparation needed. Works on an empty stomach or alongside a light meal.
The protein comes from egg whites, which are a complete protein source, meaning they contain all essential amino acids. This makes the bar a reasonable option for those who avoid dairy but still want a quality protein source in a snack format.
Based on the ingredient list — egg whites, dates, almonds, cashews, and blueberries — the bar does not contain dairy-derived ingredients. However, if you have a specific allergy concern, check the packaging for full allergen and cross-contamination information.
Dates are the primary sweetener, which means the sweetness is natural and comes alongside fibre rather than a refined sugar spike. The blueberries add a mild tartness that balances it.
It works best as a snack or a gap between meals rather than a full meal replacement. The ingredient profile is solid, but a single bar is unlikely to provide the calorie volume or full macro balance most people need from a main meal.
Anyone with an egg, tree nut (almond or cashew), or blueberry allergy should avoid it. Check the packaging for full allergen details, including any advisory statements about shared manufacturing lines.

I've tried loads of protein bars and most of the 'fruit' flavours taste like artificial sweetener with a vague memory of fruit. This one actually tastes like blueberries. The texture is dense and chewy — not soft and spongy like the ones full of syrups. I keep a couple in my bag for the commute.

Started buying these during half marathon training. Easy to get down after a long run when you don't want a full meal but need something with actual protein. The ingredient list is dead simple which I appreciate.

The bar itself is great — clean ingredients, decent protein hit, holds you over until lunch nicely. My only gripe is the price. At £43.99 for a box, it's a stretch to justify as an everyday snack rather than an occasional treat. Will keep buying but I do wince at checkout.

Swapped from a big-name bar that shall not be named. Way fewer ingredients and doesn't leave that weird coating on your teeth. Happy with the switch.

I've worked my way through most of the range and the blueberry is my favourite. There's a slight tartness that stops it being too sweet. Perfect mid-morning when I don't want to think about food but know I need something before a 1pm meeting.
