Coca-Cola Enterprises is helping retailers get their energy drink sales in shape by launching zero calorie Relentless Mango Ultra, available in March.

Mango Ultra is available in 500ml £1 price-marked and non-price-marked cans.

The move follows the re-launch of the brand’s zero calorie Relentless Origin Ultra variant last year, which went on to become the brand’s fastest selling product.

Caroline Cater, operational marketing director at CCE, said that the energy drinks sector is continuing to grow, with light variants growing twice as fast as regular ones.

“Relentless is set to help retailers drive sales by offering further choice in the zero sugar energy drinks segment,” she added.
