Is FNC right for you?
This is not a beginner coaching program. The Functional Nutrition Coaching (FNC) certification is built for coaches who already have a foundation and are ready to go deeper than any other certification on the market.
This is for you if…
- ✓ You already hold a nutrition or fitness certification
- ✓ You have 1+ year of coaching experience (online or in-person)
- ✓ Clients keep coming to you with PCOS, thyroid issues, low testosterone, perimenopause, gut problems, hormonal imbalances, unexplained weight gain, — and macros aren't solving it
- ✓ You want to charge premium rates by being the coach who actually understands the labs
- ✓ You're ready to add a functional health tier to your existing business
This is NOT for you if…
- ✕ You're brand new to coaching and looking for a foundational cert
- ✕ You want a business-building program (that's Macro Mentorship)
- ✕ You're not comfortable with science-dense curriculum and a root cause approach
- ✕ You're looking for general nutrition education without clinical application
Prerequisites
All enrollees must meet both requirements before joining:
- A current nutrition certification from an accredited body, OR a BS in science or a related field
- 1+ year of online or in-person coaching experience
The gap in the market
The clients showing up in your DMs have problems that macros alone can't solve.
They've been dismissed by their doctors. They've tried tracking. They're doing "everything right" and nothing is working. They don't need another meal plan. They need a coach who understands what's actually happening inside their body.
01
Her thyroid labs came back "normal" — but she's exhausted, gaining weight, and losing hair. You want to help but don't know what to look for.
02
She has PCOS and every diet attempt backfires. You're guessing instead of coaching from data.
03
Her gut is a mess, bloating, food sensitivities, irregular cycles. You know gut health matters but have no system to address it.
04
She's perimenopausal, stressed, and not responding to a standard deficit. You need hormonal context to coach her effectively.

What coaches inside FNC are saying
One of the best decisions I've made. Just got a text from a friend whose friend was brushed off by her doctor and her symptoms were dismissed — similar to what I experienced from more than one provider myself. So thankful you helped me get answers, feel better, and now help other women do the same.

This certification has been the most challenging, interesting, mind-blowing one I've done. @eveguzmanofficial is truly the GOAT educator. So grateful I get to sit under her mentorship.

When I started this course, she was the #1 person on my mind. I would love to do anything to give her just a little bit of relief. Thank you so much for reviewing labs with me and all of your insight. I am forever learning in this course.

FNC Student · Applying learning to real client cases
I wasn't able to join live but catching up on the case studies now and I really love them — they bring everything we're learning together and show how to work through it with real clients. I hope we can do some more!

Your instructor
She didn't just study the science.
She didn't just study the science.
She ran the labs.
Eve Guzman spent nearly two decades as a Medical Laboratory Scientist, running tests, analyzing blood chemistry, and studying hormones, gut markers, and metabolic dysfunction in clinical and research settings. Then she built MacroU, where she has certified over 1,800 coaches worldwide.
FNC exists because Eve sat on both sides of that equation — and realized no one was bridging them. The science is in the labs. The application is in the coaching. FNC teaches you to do both.
