‘Part of the 500 calorie meal deal’ from Boots, apparently. It’s an own-brand offering from the high street store, one of two flavours they have for sale. It’s clearly aimed at the calorie conscious, providing only 16 calories per can, but it does manage to cram in actual real orange juice. That would explain the most natural orange flavour I’ve tasted in an energy drink. It’s sharp, but fortunately watered down to the point of being just about right, and it packs 32mg/100ml of caffeine. On a karmic scale – it probably balances bad-for-you with good-for-you.
