For several years, I struggled with autoimmune conditions and hormone imbalances that left me exhausted, discouraged, and unsure of what the future held. Despite trying countless strategies and spending a great deal of money on different approaches, nothing truly helped me get to the root of my health struggles.

That changed when I found FNR. From my very first interaction, I could tell this was not just another health practice. Lindsey, the wellness concierge, guided me through onboarding with such warmth, clarity, and professionalism that I immediately felt at ease. She was always just a phone call away, consistently greeting me with her pleasant, authentic disposition every time I walked through the door. These first impressions set the tone for everything that followed.

Jennette, the founder of FNR and my RDN, went far beyond surface-level care. She asked...

If you are looking for a Functional Nutrition approach for your health journey, there is no better place than Functional Nutrition Resources. I could not have gotten to where I am today without them. What is so special about FNR is that they walk you through every single step - through all the positive things and all the challenges. Every single change, question or win…they are there. You do not have to go at it alone, and that really makes a difference. For years, I had been struggling, and everything that I had tried before FNR was not solving my issues. I felt so alone and lost. When people would ask how I was feeling, I could hardly convey what was going on, because I did not know what was truly going on myself. I was at the point of helplessness, like I would never have a normal life being able to do the things I wanted to do (and should have been able to do in my 30’s). When I...

In 2003, I was diagnosed with osteoporosis at age 54 that got progressively worse over the next several years. In 2017, I was diagnosed with an underactive thyroid gland, started having constant bouts of IBS-D, brain fog, joint pain, had constant UTIs and brain fog, and just felt lousy most of the time. In 2018, my new primary care physician ordered a colonoscopy and an endoscopy. The endoscopy revealed that I had gluten sensitivity. No one in my family has ever had celiac or gluten sensitivity. So, I stopped eating gluten. I learned that my gluten sensitivity was the likely cause of my thyroid issues (which my new doctor told me was Hashimoto’s thyroiditis). I always had difficulties digesting dairy, so I also stopped eating dairy. The diarrhea continued into the fall of 2018, so my new doctor suggested that I make an appointment with FNR. I signed up for their help at my first...

I came to FNR after years of hearing there is nothing wrong with you, your blood work is normal, you need anxiety medication.

I had a ton of fatigue, times where I could not breathe, I could not do my daily 40-50 min walks, if I tried I would have to take a 3 hr nap. I had to retire early due to the fatigue and overwhelm. I had to hire a house cleaner and someone to mow my lawn this year as my health continued to tank with no one curious enough to dig deep for and with me. No one was hearing me. I look fine and my labs are normal - it must be in my head. It was not in my head!

In two months the FNR program has turned my health around. My motivation and energy have returned, my brain is functioning well, I have zero anxiety, I am not dragging around a bunch of fatigue and I can breathe. I have a ways to go as I can't yet, walk my normal 40-50 minute route in...
