Never guess on your nutrition strategy again.
Most people think “eating healthy” should solve everything…
But fatigue, bloating, and brain fog often come back.
Why?
Because quick fixes and boxed diets don’t uncover YOUR unique burdens.
That’s exactly why I built Reset & Rebuild.
✔️ We start with your Functional Health Assessment to identify your top system priorities.
✔️ Then we move through elimination & reintroduction to discover which foods fuel you vs. drain you.
✔️ Finally, we guide you through a 90-day recalibration to rebuild lasting habits and reset your metabolism.
This isn’t about perfection. It’s about clarity, confidence, and a strategy built for your body.
Live class begins October 7th.
Join Reset & Rebuild today and stop guessing your way through nutrition.

Most people don’t realize this:
America has world-class emergency care… but when it comes to chronic issues like fatigue, diabetes, or autoimmune struggles, the system falls short.
Why? Because chronic problems can’t be fixed in 12 hours. They need time, personalization, and a plan that works from the inside out.
That’s exactly why I created the Reset & Rebuild Nutrition Program.
It’s built around uncovering your unique burdens, then guiding you through elimination, reintroduction, and a 90-day recalibration plan.

New program launching Oct 7!
Enrollment is open for the Reset & Rebuild Nutrition Course!
This is a 4-week small group experience that helps you finally get clarity on what foods fuel you… and which ones hold you back.
💡 This isn’t another diet or detox.
Built on a functional medicine platform, this system helps build lifelong nutrition habits with personalized strategies, live coaching, and a clear plan for the holidays & new year.
Sometimes the real issue isn’t under-training… it’s RED-S.
This hidden performance killer can hold you back even when you’re doing everything “right.”

Rarely do we get a few uninterrupted hours to dive deep into technique.
But when we do, it’s powerful.
Grateful for such a talented team of talented therapists who are always eager to learn and refine their craft.
Yesterday we worked through detailed strategies for the shoulder, neck, and knee, sharpening skills that directly impact patient care. 💪🧠

Attention Athletes -
Still training hard… but not making gains?
⚠️ If you’re stuck in a performance plateau, RED-S could be the reason.
It’s more than under-eating, it affects your hormones, sleep, recovery, and energy.9
Most athletes have NO idea it’s happening but it’s one of the top reasons high-performers burn out, break down, or stop seeing results.

It’s been a while, so I wanted to start fresh with something that’s been coming up a lot lately.
You know that feeling when your labs say you’re “fine”… but you still feel off?
You’re not imagining it. And you’re definitely not alone.
Here’s what most people don’t realize:
“Normal” doesn’t always mean optimal.
The annual physical was built to catch disease, not help you feel your best.
Your symptoms do matter, even if your labs say otherwise.
And the sooner we catch dysfunction, the easier it is to reverse it.
That’s why I believe early intervention is the new prevention.
When we put it all together...
Your story, your symptoms, and the right testing...
We can create a personalized plan that finally gives you clarity and direction.
No more guessing. No more settling.
Just real answers—and a better way forward.

Hi I’m Dr. Joshua Bletzinger DC, Doctor of Chiropractic, Certified Chiropractic Sports Physician ®, Certified Athletic Trainer, with countless postdoctoral training hours in functional medicine, clinical nutrition and functional endocrinology. In 2004 I opened my first chiropractic and sports medicine clinic in Geneva, Illinois.
Since 2004 I’ve morphed Performance Chiropractic through 3 expanding clinics to what is now known as Fox Valley Integrated Health. My current clinical services are functional medicine and physical medicine. My clinical focus is to help people reverse chronic health challenges such as type 2 diabetes, auto-immune conditions, and cognitive impairment. But there are a handful of other clinical services I still provide as we see a major healthcare reform happening around us.
In the beginning of my practice years, functional medicine was just a blip on the radar so I focused on what I knew all so well… sports injury. While I grew a high volume chiropractic and sports medicine practice I was taking care of Olympic figure skaters and professional hockey players. I provided sports medicine services to a local high school and unconditionally coached youth hockey.
But things were changing for me. I was not the youthful hockey player I once was. I was seeing my dad’s health fail under type 2 diabetes. I was seeing my grandmother losing the battle against dementia. I was foreseeing the health challenges stacking against me.
That's when I sent the discipline of functional medicine to the front of my services. My personal mission was easy… quit aging and don’t get sick! And so that’s what I do now. I help people rescue their health and slow down their aging process. I use a proprietary method of functional medicine and work with a wide range of health challenges.
If I'm not at the clinic helping patients I'm usually at home with my beautiful wife and high energy young daughters cooking food and working around the house.
