Pro Athlete Supplementation was formed as a result of a successful winning partnership between Jon Williams, BSc, WRU National Squad Nutritionist and Darren Campbell, MBE, Olympic Gold and Silver Medalist. Jon was responsible for Darren’s nutrition during the last 10 years of his career where he amassed his gold and silver medals. At the time when Darren was close to retirement Jon suggested that they form a company to develop the most effective sports nutrition products for professional athletes, football and rugby players. Hence PAS was formed.

Providing athletes with products to enhance their recovery and performance was our starting point.


  • Formualtion over Price
  • Advice before Sales

Athlete safety was always a priority. PAS is fully committed to the Informed Sport Testing Protocol and we batch screen every product we produce. Please see www.informed-sport.com for more information.



Informed-Sport is a quality assurance programme for sports nutrition products, suppliers to the sports nutrition industry, and supplement manufacturing facilities. The programme certifies that all nutritional supplements and/or ingredients that bear the Informed-Sport logo have been tested for banned substances by the world class sports anti-doping lab, LGC. Athletes choosing to use supplements can use the search function above to find products that have been through this rigorous certification process.



Since we formed the company in 2006 we have established a solid reputation amongst the elite of professional football and rugby clubs for producing research backed products that contain active ingredients at functional dosages. We ensure our clubs and athletes are provided with a first class service as we realise the demands of professional sport. Jon is the WRU National Squad Nutritionist, worked as consultant nutritionist for the British and Irish Lions 2013 Australia tour and 2017 New Zealand Tour.  Darren provides speed coaching consultancy for elite athletes and has worked with premiership football and rugby clubs. At PAS we are passionate about helping athletes, every product we develop is research backed to make sure our reputation stays high.

Our product range is constantly evolving based on research and feedback from professional sport so join the PAS team and stay ahead of the game.
