PNE Level-1 With ISSN-SNS Student Testimonials

Thousands Certified Globally.  What Do The Previous Students Say?

The importance of nutrition in performance is well-known, yet most certifications will barely scratch the surface or offer a “Nutrition 101” version of the information. The SNS certification on the GPNi portal is different - the depth of the knowledge you’ll learn in this course goes above and beyond.  It will set you apart as a fitness professional.” ”

Holly Priestland - United Kingdom 

"I am so happy I signed up for the SNS certification. I learned much more about sports nutrition than I had originally imagined.  To grow your career in fitness, where nutrition is often 80% of results, understanding and being certified is key.  Being certified by the global authority is also key.”

Emanuele Mediati - Italy

"I am a health and fitness enthusiast and already am a nutrition coach; however, I wanted specifically to learn about sports nutrition and from the top-level experts and researchers in the game. 

Icee Guinto - USA 

"I am passionate about learning nutrition, specifically wanting to learn more about performance nutrition.  I wanted to learn online as I am busy, also to be internationally certified is why I chose to be certified on the GPNi portal.

Frequently Asked Questions

A question often asked is why both the PNE-L1 + ISSN-SNS, also the PNE-L2 Masters + ISSN-CISSN (Certified Sports Nutritionist) certification course by the GPNi, are superior compared to other sports nutrition certifications in the world, such as:

  • NASM-CSNC (Certified Sports Nutrition Coach) 
  • Precision Nutrition PN Level-2 Masters (Master Health Coach)
  • ISSA – Nutritionist Certification 
  • ACE – Fitness Nutrition Specialist 
  • Clean Health Institute – Performance Nutrition Coach 
  • Sports Nutrition Association – Certified in Applied Sports Nutrition 


There are many reasons why the GPNi international certifications course is superior to all others. Please review below these five key points that make this certification superior to other sports nutrition certifications in the world:

Point One: Created by The Real Experts & Pioneers  

The #1 reason is that NONE of these other sports’ nutrition certifications are created by experts in the field, but rather copied and pasted works from other research publications. Other sports nutrition programs are cookie-cutter online, simple courses made for the mass market and simply there to make money, but not bring any real tangible value to the students. Often the is the case, the materials themselves are put together by interns or outsourced to 3rd parties. 

The authors and creators of the ISSN certifications and all course content by the GPNi are created by the original Ph.D. researchers and pioneers of sports nutrition.  

If you want 2nd or even 3rd hand-non-authentic content that is likely outdated, then the other certifications may be for you. If you are enjoying the most updated, science-backed, authentic, and directly from the source, then the GPNi certifications courses are for you! 

Point Two: CISSN The Only Globally Recognized & Respected Certification 

The ISSN certifications and courses by the GPNi are the only truly recognized academic and university-recognized certifications. Many dieticians, nutritionists, and others that do not have enough knowledge in Sports Nutrition will elect to be certified with the ISSN-CISSN, as the CISSN (standing for Certified Sports Nutritionist) is the only globally recognized acronym they can use next to their name and credentials. You will see many academics and master-level trainers with their names and the “CISSN” acronym next to their names. 

None of the other cookie-cutter sports nutrition certifications have this value or respect by dieticians and nutritionists worldwide. 

 Be proud to flash your credentials next to your name, “John Smith, CISSN, or Jane Smith, CISSN,” like no other certification can offer. 

PLEASE NOTE: For those looking to enroll in the PNE-L1 + ISSN-SNS, this is your first step towards obtaining the master’s Level certification as you must first have Level-1 before enrolling into the Level-2 Masters's course.  Other entry routes are if you are pre-qualified to do so (dietician, nutritionist). If so, contact us through to see if you are, or apply directly with the “GPNi Masters Pack,” which includes both PNE-L1 + SNS and PNE-L2 + CISSN together with a package price.

Point Three: Only Dedicated True Sports Nutrition Certification 

All the ISSN certifications on the GPNi portal are dedicated to the highest level of sports nutrition, research, education, and certification. The GPNi, the Global Performance Nutrition Institute, is the official and exclusive online education partner for the ISSN for the International Society of Sports Nutrition.  

The GPNi portal is only dedicated to sports nutrition, nothing else. At the same time, all the other programs are a jack of all trades, with everything from Yoga to Personal Training, Strength and Conditioning, and even rehabilitation certifications. They cannot be experts, especially in sports nutrition, if they are to keep up with all the science and research. 

Point Four: Live Access to Experts  

Exclusively through GPNi, get “access to experts” with the “live” classes. Ask questions to the researchers and top-level experts in the world of sports nutrition to grow your knowledge to a new level.  

GPNi portal has a unique blend of online live classes and on-demand professional filmed video tutorials. Get the best of both flexible online learning, real 360-degree education, and the ability to ask expert questions and learn. Plug into the “live” class schedule when your schedule permits to take your learning to a new level and study on your schedule with online professionally filmed playback video tutorials with Ph.D.-level expert lectures. 

Point Five: Who You Know, Not Just What You Know 

At the GPNi, you will be placed into a live cohort class for the “live” education classes. Within each class, you will be meeting, networking, and learning from other students from all over your country and, in some cases, all over the globe. At the GPNi, we have seen countless students upgrade their career paths simply by meeting new contacts and growing in the sports nutrition industry by knowing more people and thus having more opportunities. None of the other certifications have “live” classes, group assignments, or the ability to offer a global network in sports nutrition.  

As stated in Point Three above as well, the other “so-called” other sports nutrition programs are not dedicated to sports nutrition but a jack of all trades. They also lack any solid network globally in sports nutrition. 

Procedure After Enrollment

You will be able to begin your certification courses by the GPNi immediately after enrolment with the on-demand online tutorials and digital course book. 

Timing Of Certifications & Study

Both the Level-1 and Level-2 certifications can be self-paced.  You can take your time with lifetime access to the course content online for all active members yearly.  The live cohorts run throughout the year, and you can access these by booking in with the administration to determine which live class dates suit your schedule.

PNE Level-1 + SNS

Most people complete this Level-1 certification within 5 months after beginning and a maximum of 8 months.

PNE Level-2 Masters + CISSN

Most people complete this Level-2 Masters certification within 8 months after beginning and a maximum of 12 months.
