Why choose nutrition x?
At Nutrition X, our mission is clear: to fuel athletic performance with science-backed, 100% Informed-Sport certified nutrition. Driven by passion and expertise, we go beyond products, supporting the sports community through education, innovation, and a commitment to safety—no gimmicks, just reliable, effective support for every athlete.
OUR STORY
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.
