Science in Sport develops, manufactures and markets innovative nutritional products for both the professional sportsperson and the local enthusiast. With products ranging from energy gels to whey powders, Science in Sport sells in a range of retail channels; including specialist sports retailers, major grocers and online.


One in four Brits will have consumed a sports nutrition product in the past 3 months*. The data doesn’t lie: consumers have never been more health-conscious – and their buyer behaviour is driving a boom for the sports nutrition industry. With the global sports nutrition market forecast to be worth $45.27 Billion by 2022, there’s a big opportunity available for the specialist vendors that can secure custom from interested shoppers. But the success of these nutrition specialists will depend on the customer experience they can deliver to secure loyalty and return purchases – and that’s especially true online.


SiS wanted to grow loyalty by providing website visitors with an experience to match its innovative products. With Yieldify’s expert advice, bespoke design service and custom-made campaigns, SiS has achieved an 82% uplift in conversion rates.
