What is the Precision Nutrition Certification?

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 most recommended nutrition education program in the world, with nearly 100,000 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.

Read detailed reviews of the Precision Nutrition Level 1 Certification and see for yourself the kind of results our students get.

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.

Fast Company rated Precision Nutrition one of the
most innovative companies in health and fitness.

The principles behind Precision Nutrition are the same type of advice Dr. John Berardi has been sharing with Olympians and professional athletes.

The experts that other
experts come to for help.

Developed and written by John Berardi, PhD, CSCS, Krista Scott-Dixon, PhD, Brian St. Pierre, MS, RD, Helen Kollias, PhD, CSCS, and Camille DePutter, the Level 1 Certification is the synthesis of everything we’ve learned over 15 years of coaching and research in nutrition.

John Berardi PhD, CSCS, Co-Founder

Dr. Berardi (a.k.a. “JB”) is a co-founder of Precision Nutrition, which has become the world’s largest online nutrition coaching and certification company. He’s an advisor to Apple, Equinox, Nike, and Titleist, and was recently selected as one of the 20 smartest coaches in the world.

I’ve devoted my entire career to making health and fitness something that’s achievable and attainable for every type of person, from every walk of life.

Precision Nutrition advises organizations around the world, coaches elite athletes & sports teams, and has been featured in leading publications. There’s a reason over 2 million people come to our website for advice every single month.

“John Berardi is one of the top sports nutrition experts in the world. He concentrates on simple solutions that actually work. That's why he's a key part of our high-performance team.”


“I was really looking to dial in and optimize my nutrition for performance and recovery. Precision Nutrition was a terrific resource to help me reach my goals.”


“I have known JB for almost two decades. He has been – and continues to be – my ‘go-to guy’ for all things nutrition and change psychology; he has what all great teachers have: an ability to take complicated constructs, and communicate them in a way that makes sense to simple people like me.”

“Thanks, John, for making me bigger and stronger. You are the best thing that I've added to my training regimen."

PN Graduates

The Precision Nutrition Level 1 Certification is trusted by elite health and fitness professionals worldwide.

The Level 1 Certification allows you to immediately affect positive changes in the lives of your clients. One of the things I absolutely love is the focus on the big things first — the behavioral modifications, and the quick fixes that can yield dramatically improved results.

Eric Cressey, MA, CSCS

What really makes a great coach, and what I think works so well in the PN Level 1 program — it’s not about telling someone to do something. It’s about knowing what questions to ask, and then leading the person in the right direction.

Jonathan Goodman, founder of the Personal Trainer Development Center

The Level 1 program gives you the skills and tools that you need to actually go out and do it. So it’s not just academic information. It gives you everything you need to be a successful coach.

Marie-Josee Perrier, PhD

I think the coolest thing about the program is the promotion of behavior change. If I can teach my patients how to change, I can make a world of difference without having to pull out my prescription pad. In the end, when people tell me they want to teach other people how to live healthier lifestyles, I tell them the Precision Nutrition Level 1 Certification is the way to go.

Spencer Nadolsky, DO, Bariatric Medicine

As I was going through the course I realized it was perfect; it’s exactly what I wanted and needed to learn. The information it taught me vs. the 4th year nutrition course I took as a Kinesiology student.. it was like comparing apples to oranges. The nutrition course was good. But the Precision Nutrition Certification was that much better.

Adam Lloyd, CSCS

We have tried every nutrition program out there. Precision Nutrition is by far the most thorough, informative, effective system we have seen. Not only is our entire team PN-certified, we recommend it to every gym we consult with.

Alwyn and Rachel Cosgrove

This certification is not only incredibly thorough, it also mixes practicality and reality into the program. The Precision Nutrition team is as interested in science as they are behavioral modification. And that's the true way to get results.

Martin Rooney

Not only will you come away from the certification with a tremendous amount of knowledge about nutrition — you will also gain valuable skills on how to assess and help each client you work with.

Kristin Schell

The Precision Nutrition Certification stands head and shoulders above all other nutrition programs because of its focus on actionable items for fitness professionals. There is simply no other course available that teaches you the art and science of coaching for every situation.

Devendra Chengkalath

From the average Joe to the professional athlete, Precision Nutrition is the system coaches, trainers and nutritionists need to add to their toolbox for optimal success. I highly recommend this certification for anyone who wants to make a lasting difference in their athletes’ performance and health.

Adam Feit

The Precision Nutrition Certification helped me to combine the science of coaching with a sustainable method of implementing that science, making me a more capable professional.

Ron Dykstra

The Precision Nutrition Certification gave me the confidence of knowing I'm following a proven method that's brought success to thousands of clients. And it shows! My own success has increased since applying what I learned.

Carolina Belmares

The Precision Nutrition Certification has added more value to my business by allowing me to use nutrition coaching with a whole range of clients. That's just one of the reasons I highly recommend the program.

Alicia Bell

Continuing the University comparison, if you decided to go back to school for a nutrition degree or to become a registered dietitian, you’d likely spend anywhere from $10,000 – $20,000 USD per year. If you did a four-year degree, you’d be looking at spending upward of $40,000 – $100,000 USD.

The only problem? Most university courses lack real-world coaching opportunities. And most professors aren’t experienced coaches. That’s why many students find that they’re stuck once they graduate.

It’s also why, in the Precision Nutrition Level 1 Certification, we’ll share a proven coaching system that’s guaranteed to get results for anyone who comes to you for help.

After coaching over 100,000 clients, we’ve seen what works time and time again. And we’re ready to share everything we know with you, so you can help your clients achieve life-changing results.

Final note

More people than ever are looking for someone to help them get healthy and fit (and stay that way for good). And the research is clear that the best place to focus first is on their nutrition.

But it’s important to understand that “knowing a lot about nutrition” isn’t enough. You must also be able to effectively help others change their eating and lifestyle behaviors.

That’s what we do every day at Precision Nutrition as we coach our own clients (no other nutrition certification company does this). And we’re ready to teach you the same science-based coaching method we’ve used with major health organizations, professional sports teams, Olympic athletes, and over 100,000 clients worldwide.

In the PN Certification, we’ll give you everything you need to feel confident, qualified, and ready to coach nutrition with anyone who comes to you for help.

Of course, if now isn’t your time, we understand. We hope this helped you understand who we are and what we do. We’ll be here if and when you need us.

But if now is the time for you to learn how to help others with their health and fitness—then the PN Certification is everything you need to get great results and build a rewarding coaching practice.

We’re excited to teach you everything we know about the science of nutrition and the art of behavior-change coaching.

But the next step is yours.

Hope to see you in the program,
