Precision Nutrition

Precision nutrition is a nutrition research, coaching and certifcation company based on sound science and rigorous research. Founded more than a decade ago by by John Berardi, PhD. Precision Nutrition has ten of thousands of users in 87 countries. It has conducted the largest body transformation study in history.

We do not sell supplements and do not promote "quick fixes." The focus is on education and research.

The Precision Nutrition System consists of two parts: the educational component, which comes in the form of the various guides and our cookbook, and the support component, which comes in the online Member Zone. These two things have come to define PN: we teach you exactly what you need to know, and then we help you all the way to your goal with expert advice and the 24/7 support of our nearly 40,000 strong community.

Precision Nutrition also trains and certifies nutrition coaches through an online education program designed specifically for use in a personal training / strength coaching environment. Included is our new textbook, The Essentials of Sport and Exercise Nutrition, a 500-page academic text written from the ground up specifically for fitness professionals. Also included is an online certification exam you can take anytime you feel ready. Finally, we provide assessment forms and other material you can use to kickstart your nutrition coaching practice.
