Why Informed Sport Certification Matters: Train Smart, Fuel Clean
When it comes to sports supplements, knowing exactly what you're putting into your body isn’t just important—it’s essential. Whether you're training at an elite level or just aiming to maximise your personal performance, quality, safety, and trust should be at the core of every supplement you use.
That’s where Informed Sport certification makes the difference.
At MaxiNutrition, we’re proud that so many of our products are Informed Sport certified. This means they’ve been independently tested for banned substances and manufactured to the highest global standards for clean, trustworthy nutrition.
What Is Informed Sport?
Informed Sport is a global quality assurance program developed by LGC, one of the world’s most respected independent testing laboratories. Their mission is simple: to ensure that athletes and fitness enthusiasts can use supplements without fear of contamination or banned ingredients.
When a supplement is Informed Sport certified, it means:
- Every batch is rigorously tested for over 250 banned substances
- The product is manufactured in a facility that meets strict quality controls
- It is trusted by elite athletes, national teams, and sporting organisations worldwide
This isn’t just about avoiding banned substances—it's about providing peace of mind. That orange Informed Sport logo is your assurance that what’s on the label is what’s in the tub, and nothing else.

Even if you’re not a professional athlete, Informed Sport certification should still matter. Here’s why:
- Peace of Mind: You don’t need to worry about hidden ingredients or contamination
- Performance Support: Products are formulated to help you recover, grow, and train harder
