About Science in Sport

We believe that the most sophisticated piece of sports equipment you’ll ever own is your body.

Science in Sport creates mechanics for the machinery of man. We’re the unseen force behind personal bests, world records and photo finishes.

At the heart of everything we do is the simple belief that if you don’t put high performance sports nutrition in, you won’t get your full potential out.

Introducing the Science in Sport Elite Partners

Elite athletes know that trusted sports nutrition is a crucial part of keeping them at the top of their field.

The entire SiS Range is Informed Tested and is manufactured at our site in Nelson, Lancashire. SiS was the first to achieve their Evolved Certification which includes testing all raw ingredients, having the manufacturing facilities tested twice a year and blind testing finished products.

This is why some of the world’s greatest athletes trust Science in Sport, whose list of partners reads like a who’s who of sporting heroes.SiS partner logos

The SiS range

The SiS range has been developed using the insight gathered from working with our elite partners and the latest scientific research. This allows SiS to lead in product development and innovation, creating the worlds’ only truly isotonic gel and the first complete recovery product in REGO Rapid Recovery​.

The range has been designed to support the four need states of endurance sport of Energy, Hydration, Recovery and Protein.


For moderate to high intensity endurance exercise over ninety minutes long, additional carbohydrate is needed to keep your energy stores fully fuelled. The SiS GO range provides a number of options in GO Energy drink powders, GO Energy bars and GO Energy gels. Our base ingredients are selected to perform optimally, taste great and deliver exactly what you need whilst out on the road, trail, or in the pool or gym.

As you exercise you sweat to regulate your core body temperature. This mechanism works well, but you have to replace the fluids and electrolytes you loose to maintain your performance and health. SiS provide both a low energy, electrolyte-only option in SiS GO Hydro tablets, and SiS GO Electrolyte for carbohydrate energy and electrolytes delivered together.

As you exercise you start to deplete your carbohydrate stores, even if you fuel optimally with 60g of carbohydrate per hour. To enhance your adaptations and get you ready to again tomorrow, you need to take on board rapidly digested carbohydrates and protein to replenish these stores and support your lean muscle mass.

SiS REGO Rapid Recovery was the first complete recovery product, providing rapidly digested carbohydrate and protein, electrolytes to aid rehydration and key vitamins and minerals to support your immune system.

We all have a natural turnover of protein in the body everyday, and this increases as we exercise. To feed protein optimally, you need to supply your body with 20-25g every 3-4 hours. It isn’t always convenient to do this with whole food, so protein products such as SiS Protein Bars and SiS Overnight Protein can be a valuable addition to your diet to provide high quality sources of protein.
