Press Reviews


With two types of carbohydrate to provide energy, five essential minerals to help you avoid cramp and the addition of protein and caffeine, Powerbar Isomax energy drink is a very effective all-in-one package.

I've used this drink on a couple of long training rides, and it definitely works for me. My preferred technique for long rides is to use a carb-only drink in my first bottle, so I started drinking the Isomax in my second bottle (both bottles 750ml) – combined with my usual array of gels and bars. I found the carb-protein drink mix kept me going in the second half of the ride with a good sustained supply of energy, while the minerals also seemed to help me avoid the cramps I sometimes get in my calves after about 70 miles of hard pounding. To be honest, I didn't notice the effects of caffeine in this drink mix (which may be because I'm more accustomed to getting my hit from caffeine enhanced gel in the last part of a long ride). But while I was obviously tired in the final few miles, I felt comfortable and my brain was still in gear.

So PowerBar Isomax works for me, but will it work for you? That depends. For a start, if you mainly ride shorter races and sportives, or if you tend not to push yourself too hard, then this type of energy product is not essential. But if you're doing road-races, long time trials or just like to crack on in a 100-mile sportive, then I'd recommend Isomax as well worth trying.

This Isomax drink is available in just one flavour: Blood Orange. It was certainly blood orange in colour, but the taste was very mild, and neither sweet, sharp or sticky – similar to PowerBar Isoactive in that regard. If you don't like the strong taste of some other energy drinks, then the mild flavour of Isomax will be a good thing. On the other hand, if you need a tasty drink to encourage you to keep hydrating, this mild flavour may not be so useful.

Cycling Fitness

The latest Isomax sports drink from Powerbar is designed to replace all the main five electrolytes lost through sweat, promising more efficient hydration.

The new high-performance drink from the energy giant has been reportedly selling our fast, and looks to offer a number of technical benefits. The main factor that jumps out at us is that the ingredients - sodium, chloride, potassium, magnesium and calcium - are said to feature in the correct ratio akin to that which you'd sweat out on the bike. Replacing lost fluid is crucial and water just doesn't cut it when your losing essential salts and sugars; so in theory we like the sound of this promise.

Other key ingredients are caffeine, of which 70mg features per serving - not excessive but a moderate dose to boost alertness - 41.5g of carbohydrate and 3g of protein, which Powerbar say will help you "perform for longer". The Blood Orange flavour is pretty palatable and comes in handy sachets or 1,200g tubs.
