PowerBar Natural Protein bar



Tasty protein bar designed to help muscle recovery after training or racing

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Among the ever-growing number of sports nutrition brands, PowerBar is one of the originals, with a wide range of bars, gels, drinks and other products – including this Natural Protein bar. It's tasty, healthy and designed to help muscles recover after exercise.

The PowerBar Natural Protein Bar's main ingredients include soya beans, peanuts, almonds and peas, which are all sources of protein. Most sports scientists agree that you need protein to help muscles recover after exercise. In a cycling context, this means if your muscles recover well after training or racing, then you're stronger or faster, or just more comfortable, the next time you ride your bike.

Unlike PowerBar's other protein bars (and protein bars from many other brands), the Natural Protein Bar does not contain milk or any animal products, and therefore is good for vegans.

The Natural Protein Bar comes in two flavours: salty peanut crunch, where other ingredients include pumpkin seeds and vanilla extract; and blueberry nuts, where other ingredients include cranberries and – you guessed it – blueberries.

A 40g peanut crunch bar gives you 12g of protein, along with 12g of carb and 9g of fat. The blueberry bar has the same amount of protein, with more fat and less carb.

In texture the bar is like a normal cereal bar; slightly crunchy, but not too hard. Certainly no danger of breaking a tooth as you tuck in. As the names imply, salty peanut bar tastes more savoury, whereas the blueberry bar is a bit sweeter, although the flavour isn't overpowering (which is a good thing) and the bar isn't over-sweet or sticky. Both flavours taste very good indeed and go well with a cup of tea after a hard ride or turbo session, and on that basis they're recommended.

On cost, a single Natural Protein Bar's official retain price is £1.50. Compared against similar - but not vegan - bars from other brands this is fair, although not an absolute bargain. For example, High5 protein bars (50g) official RRP £1.70, ZipVit protein bars (65g) around £1.75. However, most bars are discounted if you buy in bulk, and you can buy a box of 24 Natural Protein Bars for around £30, and even as low as £23, at the usual on-line stores.

As with all nutrition products, you should try a bar or two when you're not training hard, and not the day before a big ride, just to make sure the ingredients agree with you personally and have no ill effects on the stomach. Then, if you like the PowerBar Natural Protein Bar, stick with it. If you don't, then try something else.

Tell us how the product performed overall when used for its designed purpose

Whether these bars helped my muscles recover any faster than another brand's protein bar, or indeed a bowl of muesli, is impossible to say. As mentioned in the main review, when most cyclists choose a nutrition product, a lot comes down to taste, texture and whether the product sits comfortably in the stomach. On that basis performance is very good, in that the bars taste great and have no ill effects.
