Transforming my body and life in the past few years wasn’t easy work - it took a lot of perseverance. 35kg body fat loss would have been impossible without the right knowledge and attitude. Learning from the best with the GPNi® and the ISSN certification I highly recommend anyone looking to improve their lives for the better.

Over the past few years, my interest in sports and nutrition grew, while the different concepts and opinions seemed confusing. The SNS course was a challenge for me, as I have no prior educational background on this topic, but professional teaching, a well- structured outline and access to the latest science information connected all aspects to a coherent picture of sports nutrition.

I’ve always understood how important nutrition is for performance, but many certifications I found either skimmed the surface or were basic. Enrolling in the GPNi® PNE Level-1 + ISSN-SNS certification gave me the scientific depth I had been searching for in sports nutrition education. What truly sets this certification apart is the evidence-based performance nutrition it offers. It connected research with real-world application, helping me stand out in the field.

As nutrition is becoming viewed as the most crucial aspect in all fitness and professional sports, you will upgrade yourself to serve others to the highest level.

In your career, it is often as important, if not more important, to who you know, not just want you to know – with GPNi, learn and grow your connections globally!

The CISSN, by the GPNi®, is far more advanced and is the preferred certification for those who wish to provide more detailed sports nutrition information to their clients and professional athletes. SNS is a critical foundation course for those at an earlier stage in their career, or who need a foundation to begin in performance nutrition.

The SNS focuses more on the applied aspects of sports nutrition and is meant for those who do not have a strong foundation in place and need to learn the fundamentals first.

Through the GPNi®, SNS is a prerequisite in being able to apply for CISSN Masters also. Only those that have completed the SNS Certification program, or have a relevant degree in nutrition can apply for the CISSN.

For those that wish to do the CISSN, that are not yet qualified, you can learn about the "Masters Pack," which includes both the SNS and CISSN together. The GPNi® Masters Pack helps fast-track you with your career and qualifications, also has some moderate discounts for the pack as well for both.

With all GPNi courses and certifications, you will learn sports nutrition strategies backed by the most up-to-date and cutting-edge science and research. Global experts also create all courses and sports nutrition researchers.
Depending on which course and level certification you choose, you will learn the below areas + a great deal more.

  • When you eat may be as important as what you eat for athletic performance.
  • Nutrient timing incorporates methodical planning and eating whole foods, fortified foods, and dietary supplements.
  • The timing of energy intake and the ratio of certain ingested macronutrients may enhance recovery and tissue repair, augment muscle protein synthesis (MPS), and improve mood states following high-volume or intense exercise.
  • The right sports nutrition plan for the right athlete for performance and recovery.
  • The GPNi branded “Traffic Light System®” on supplementation (products) has proven to work, backed by science according to the latest ISSN research and later literature.
  • In-depth understanding of the ISSN Position Stands.
  • Ethics and best standards of practice for global performance nutrition.

Upon completing the course and being certified as a Sports Nutritionist, you will be recognized globally as qualified. No other sports nutrition or nutrition certification can offer this level of authority. Though other certifications may have content, none of it is created by the experts that did the science & research on sports nutrition.

The GPN® is unlike any other certifications and course programs currently available globally. Firstly GPNi® is the only truly global certification in sports nutrition. Others may claim to be “international” though are only offered in the English language and often only reside within one country or region. 

The GPNi® courses and certifications are now offered in: 
1. English. 
2. Chinese 
3. Japanese 
4. Many other languages launching soon. 

The GPNi® also has exclusive region partners to help localize the content also work with local regulations within each region now in:

2. Australia & New Zealand (ANZ) 
3. China Mainland 
4. Hong Kong 
5. Taiwan 
6. Japan 
7. Singapore 
8. United Kingdom 
9. More Region Partners Launching Soon

The GPNi® certifications have all been created using the most cutting-edge sports nutrition scientific studies. The authors of all the courses are all international experts, and Ph.D. level globally recognized lectures. You will not find a program or course of its kind similar or in-depth to what the GPNi® offers. 

Whilst some certifications may label themselves as “sports nutrition”, most of the time they are simply general nutrition courses with a few small details about amino acids thrown in. All the GPNi® courses cover the foundational understanding and fundamentals of nutrition, but at the same time goes very deep on all aspects of athletics and the latest research-backed sports nutrition and diet strategies that other courses do not even surface-level begin to examine. 

Many online courses offer on-demand content with a “cookie-cutter” approach to education. For those simply looking for a “piece of paper” as a certification, other programs may be easier and suit your needs better. The GPNi® approach to education is a 360° with true “classroom” like feel with our exclusive chat classroom groups and “live” classes. Learn from others with our global classroom and also get your “Access to Experts”, only through the GPNi®.
