RXBARMinis Protein Bars Variety PackWhat are you hoping to improve?
Pick a goal and we’ll tell you, honestly, whether Minis Protein Bars Variety Pack is the right fit, or what would suit you better.
Most protein bars are confectionery in disguise. RXBAR built its reputation on the opposite: a handful of whole-food ingredients, egg whites for protein, dates to bind, nuts for texture, printed plainly on the front of the wrapper because there is nothing to hide. The minis are the snack for the gap between meals, or after training when a shake is not practical, and they travel anywhere without melting into your bag.

The vanilla take on the boutique's cleanest whey: cold-processed, grass-fed isolate with nothing artificial.

The most researched supplement in sport, and increasingly in brain health, at the exact 5g dose the studies use.

Proper hydration is about salt, not just water, and this gets the ratio right, with no sugar at all.

Real protein, a genuinely short label and fruit flavours that taste like the fruit make it a convenient top-up toward a daily target rather than a treat you justify afterward.
Keep a few to hand for the days that get away from you, alongside a proper protein powder for the days that do not.

Been keeping a stash in my drawer at work for that 3pm slump. The strawberry ones are genuinely tasty — not too sweet, which I appreciated. They hold me over without making me feel heavy before the commute home. Will be reordering.

Love the mini format. A full-size bar is always slightly too much between breakfast and lunch, so these hit the sweet spot. Blueberry is my favourite.

I've spent years avoiding protein bars because of the ingredient lists. These are genuinely different — eggs, dates, nuts, fruit. That's it. I take one before my morning run and another mid-afternoon. The variety pack is a nice touch because I haven't had to commit to a single flavour. Blueberry edges it for me but both are solid.

Really rate the ingredient quality and the minis are a clever format, but at £14.99 for the pack, you're paying a fair bit per gram of protein compared to alternatives. That said, I keep coming back, so clearly they're doing something right. Docking a star on value grounds.

Bought these on a friend's recommendation and I wasn't disappointed. Strawberry flavour in particular tastes like actual fruit rather than synthetic stuff. Nice one.

I have one about 45 minutes before training — the dates give enough of a carb kick without sitting heavily. Much prefer these to gels or anything overly processed. The mini size is exactly right.
