About Science in Sport
Science in Sport (SiS) is a leading UK endurance nutrition brand founded in 1992, pioneering scientifically-based sports nutrition for athletes at all levels. The company revolutionised the industry by creating the world's first isotonic energy gel - the GO Isotonic Gel that can be consumed without water. Based in Blackburn, Lancashire, where they operate a state-of-the-art 160,000 square foot manufacturing facility opened in 2022, SiS maintains the highest standards of quality including rigorous banned substance testing trusted by elite athletes. The brand supplies over 320 professional teams, organisations, and national sports teams worldwide, and won the Queen's Award for Enterprise in 2015. The GO range of isotonic energy gels provides 20g+ of easily digestible carbohydrates using maltodextrin, maintaining a low-sugar profile. Available in flavours including Orange and Pineapple, these vegan and gluten-free gels are designed to fuel performance without causing bloating. The range also includes caffeine variants (75mg or 150mg) and electrolyte-enhanced options. SiS (which also owns PhD Nutrition) represents the gold standard in endurance sports nutrition.
