Reign Total Body Fuel is designed to be consumed pre and post workout and contains 200mg of natural caffeine extracted from green coffee beans. The no sugar, no calorie range also contains a number of ingredients intended to enhance performance, including branched-chain amino acids, which can help to prevent protein muscle breakdown, and L-Arginine, which improves blood flow and stimulates the release of growth hormones.

Additionally, the range of drinks are enriched with Vitamins B3, B6 and B12, which help reduce fatigue and normalising metabolism, and contain no artificial colours or flavours to increase appeal.

Reign will be available in four flavoured variants: Melon Mania, Razzle Berry, Lemon Hdz and Sour Apple. Each 500ml can has warrior-themed packaging and will be available in plain and price-marked packs (PMP £1.49).

The launch will be supported by event and venue sponsorships and sponsored digital content and in-store POS materials featuring global and local fitness influencers.

Simon Harrison, vice-president of commercial development at Coca-Cola European Partners, said: “There is a growing demand amongst 18-to-35 year olds who want a drink to help them achieve maximum results when they work out without sacrificing on taste. Reign perfectly matches this demand by offering an energy boost with vital proteins and vitamins to help consumers perform at their peak, and aid recovery long after the hard work is done.

“Within eight months of launching in the US, Reign gained a 25% market share of workout energy drink sales so we’re confident that the brand and its great-tasting liquid with functional benefits will appeal to consumers in GB.”
