SiS Performance Solutions

Science in Sport fuels the success of over 320 Elite teams and organisations around the world.

The SiS Performance Solutions team drives the deepest component of these partnerships; providing bespoke and innovative research, testing, guidance and product solutions to many of these Elite teams and individuals.

No other sports nutrition brand has access to the breadth and quality of Elite athletes that SiS does within its roster.

We work with our Performance Solutions partners across the areas of both Performance Knowledge and Performance Delivery to improve their nutritional capabilities – and thus overall performance.

We conduct world class scientific research with our Elite partners to gain unparalleled insights into the nutritional demands of athletes at the very pinnacle of their sport.

We then take these insights and coupled with the deep expertise provided by our incredible in-house science team, translate the learnings to deliver bespoke products and practices for our partners.

Many of these custom products then go on to shape company product strategy and ultimately become available to all consumers.

This all happens at the frontline of Elite sport – a because winning doesn’t happen in the laboratory; it happens on the field, track, road and court.
