Science in Sport

At Science in Sport, our goal is quality and performance above all, to help all athletes achieve their goals.

Science in Sport was born out of the desire to provide the best nutritional products and advice to athletes.

The company blends qualified sport scientists, food technologists and a physician with passionate athletes and athletes who have competed from the local level to the world stage.

As a result of all this experience, they have unprecedented knowledge of the nutritional needs of athletes. Science in Sport initially grew up in cycling thanks in part to the use and approval of products by Chris Boardman, who loved the company’s ethics, and helped inspire the creation of REGO, a full recovery sports fuel.

It wasn’t long before the word began to spread and Science in Sport products became more popular at the highest level of many other sports.

To date, Science in Sport has helped to win Olympic gold, world championships, Premiership titles and set numerous world records.
