What Certified Practitioners and Coaches Say
“After completing the certification, my perspective has completely shifted. … There is so much science behind using GLP-1 that I would have missed had it not been for this certification.”
Dr. Cori Cooper, pharmacist, life coach, and master certified health and nutrition coach
“The GLP-1 Optimizer™ Certification Course gave me quality education to first understand, then be able to speak with confidence to clients about everything from how GLP-1 is naturally secreted within our own bodies and how to improve our own, to the GLP-1 RAs currently prescribed today.”
Nicole Gleason, NBC-HWC, FMCHC, CFNC
“I feel confident supporting anyone, whether they’re considering a GLP-1 agonist, choosing not to use it, or transitioning off while supporting their body’s natural function.”
Ashley Stewart, Health Coach
“I’m already implementing much of what we learned, and have refined how I speak about the system as a whole, as well as the medications.”
Beverly Mazza, BSN, RN, NC-BC
Why This Is the Leading GLP-1 Certification and Community

Your patients and clients are already asking about semaglutide (Ozempic®, Wegovy®), tirzepatide (Zepbound®, Mounjaro®), orforglipron, retatrutide and, soon, amylin-based medications.
They want your help with recommendations to optimize outcomes, reduce risk, and make choices based on their personal health today and tomorrow. This GLP-1 certification course gives you a system and a standard of care you can explain clearly to patients, colleagues and referral partners.
The Body as an Ecosystem
Most GLP-1 training focuses on the medication alone or offers mass recommendations for micronutrients and training. This certification explores the roles of the body’s own weight health hormones and invites your curiosity about the whole person to personalize their plan.
A Proven 4-Phase System
GLP-1 Optimization™ maps out assessment, phase designation and personalized protocols across nutrition, supplementation, medication and lifestyle.
Built for a Thriving Business
Business and marketing guidance, networking opportunities and collaborations to help you elevate your visibility and create care efficiencies.
Ashley Koff RD first “met” these hormones in 2004 and the medications in 2005, and has been developing her Weight Health approach for the GLP-1 era ever since. She has helped thousands of patients, and now hundreds of practitioners, with this approach. As she works to make weight health the standard of care nationwide, she invites you to join the growing army of practitioners and coaches using her proven program and translating it into their own practice.

GLP-1 Certification FAQs
Who can become GLP-1 certified?
The certification is available for all practitioner types (MD, NP, DO, ND, PharmD, CNS, RD, PA, DC) and certified coaches. There is a distinction between certification for a licensed practitioner and for a certified coach.
How long does the GLP-1 certification course take?
The training is 5 recorded modules with multiple lessons that you complete at your own pace, followed by the certification exam. While you can likely get through all the modules in a long weekend, we recommend giving yourself 3-4 weeks to get through all the content. It is approved for 12.25 CPEUs.
Is this GLP-1 certification approved for continuing education?
Yes. The GLP-1 Optimizer™ Certification is approved for 12.25 continuing education units (CPEUs) for registered dietitians. Continuing education for NBC-HWC coaches and CNS is coming soon.
Do my patients or clients need to be on a GLP-1 medication?
No. The GLP-1 Optimization™ System supports people on a GLP-1 agonist, considering one, transitioning off one, or choosing not to use one, because it focuses on optimizing the body’s own weight health hormones.
What’s included in the community and quarterly live sessions?
The community is where you ask questions, brainstorm patient and business cases, and network with other certified practitioners and coaches. Each quarterly live session with Ashley and Keri covers what happened in the news, what’s coming next and how to factor it into your quarter, with time for your questions.
What opportunities exist for GLP-1 Optimizer™ certified practitioners and coaches?
Ashley Koff RD, USA Today bestselling author of Your Best Shot, collaborates with companies and practitioners seeking certified individuals. Certified practitioners and coaches are eligible for consumer, practitioner and business referrals, and one module is dedicated to identifying and securing business opportunities within your own and external networks.
What if I don’t pass the test?
You will be given the opportunity to complete another test within a month of being notified of your initial test results. If you do not pass a second time, we may recommend you don’t pursue certification at this time or consider redoing the program.
Can I get a refund?
Because you get access to the community as soon as you join, we do not offer refunds once you have access. If you have any questions before you purchase, email hello@thebetternutritionprogram.com and we’ll help you decide.
Do I have to be a Nutritious Life coach or part of The Better Nutrition Program to participate?
No, this project is brought to you independent of our roles in our companies. We are taking advantage of some of those resources to keep costs to you as low as possible but you do not have to join or purchase resources from either company.
Can I sign up if I am not a coach, student or practitioner?
If you are interested in this for yourself, we love that! It is likely you can go through the program but you also may do better experiencing it in action. Email hello@thebetternutritionprogram.com before you purchase so we can determine what’s better for you together.
