OUR STORY - test update
The “X” in Nutrition X stands for expertise. Our passion for sport and nutrition drives everything we do. In 2014, our Director, James Markey, acquired Nutrition X and alongside our team of professors, have developed one of the most scientifically backed sports nutrition ranges available today. In 2021, James’ wife, Naomi Christiansen, joined the team as joint Director, and together, they have built a brand that champions elite-level sport, with education, science, and safety at its core.

Clean Sport
We understand how important it is for athletes to be sure that any supplement they take is safe to do so. That’s why we’re proud to be fully Informed-Sport accredited, meaning that each and every one of our products has been rigorously tested and certified under the prestigious Informed-Sport programme.
When using a Nutrition X product, you can be safe in the knowledge that it has been tested for, and is free from, a wide range of substances listed on the World Anti-Doping Agency banned substance list. We also make each of our batch test certificates readily available for extra reassurance.
Not only are we committed to ensuring our own products are safe, but to making sure that we’re doing all we can to support change for the better in the sports nutrition market. That’s why we’re proud to be members of ESSNA, supporting their ongoing campaigns to secure appropriate EU legislation on sports supplements.
