The #1 rated PN Certification gives you the knowledge and skills you need to transform people's health and lives forever.


A deep understanding of nutrition, the authority to coach it, and the ability to turn what you know into results.

The PN Level 1 Certification will teach you all that, including the methodology we’ve tested, refined, and proven with over 100,000 coaching clients.

Imagine how good it would feel to have confidence in your nutrition knowledge… to finally feel qualified to give nutrition advice… and to feel ready to coach anyone to better health and fitness.

The research is clear: To help people get the results they want, the best place to focus is on their nutrition.

But understanding nutrition science is only a small part of what it takes to get people the results they deserve. It only matters if you also know how to help someone change their behavior.

The Precision Nutrition Certification is the only program in the world that teaches you both. And our knowledge isn’t based on theory.

We’re the originators of behavior-change nutrition coaching, and since 2005 we’ve coached over 100,000 of our own clients. (No other nutrition certification company does this.)

We know what works, because we coach real people every single day.

That’s why we’re the #1 recommended nutrition coaching certification in the world, with over 150,000 health and fitness professionals choosing to get certified by us.

Now we’re ready to teach you the nutrition science you need to feel competent—and the behavior-change coaching skills you need to deliver sustainable results for anyone.

In the PN Certification, you’ll learn a proven and practical system that shows you exactly what to do at every stage of the nutrition coaching process—from the very first time you meet with a client, until they reach all their goals.

No matter where you’re at in your career, you can become Precision Nutrition Certified… and learn how to coach nutrition in the most effective way possible.

And you can use your new coaching skills to earn a great living doing what you love, either full-time or as a flexible side business.

(According to a recent study by the Personal Trainer Development Center of over 1,200 coaches, those who have a Precision Nutrition Certification earn more money— 11% more than those with other certifications.)
