Nutrition counseling backed by functional testing and real answers

Get personalized, root-cause nutrition care that is covered by insurance.

At Functional Nutrition Rx, our team of registered dietitian nutritionists goes beyond symptom management and builds a plan around your specific needs, labs, and real life.

Most nutrition care treats everyone the same and your body isn’t everyone’s.


You’ve done the diets and maybe tried a program or two. 

Possibly even had labs run, only to be told everything looks “normal.” And yet you’re still exhausted. Still not seeing results. Still frustrated.

The problem isn’t your willpower or your effort. The problem is that most nutrition care treats everyone the same.

You deserve a plan specific to your individual needs and wants. You deserve a provider who will actually dig in.

This is what nutrition care looks like when it’s built around you.

Root-cause, not just symptom management

We use advanced functional testing—including the DUTCH hormone test, GI-MAP, Mycotoxins, Organic Acids and food sensitivity panels—to get to the why behind how you’re feeling.

Truly personalized plans for your needs

No templates. No one-size-fits-all protocols. Your nutrition plan is built around your unique biology, lifestyle, and goals—and designed to actually fit into your real life.

Nutrition services covered by insurance

Most root-cause nutrition care is cash-only and out of reach. We accept most major insurance plans, so you can get the expert, individualized care you need without the out-of-pocket burden.

We work with most major insurance plans and are in-network with a growing list of providers. Our team handles the verification process so you can focus on your health.

  • My dietitian had a gift for connecting the dots between lab work, daily habits, and long-term goals, helping you understand why your body is responding the way it is and how to support it sustainably. My RD truly embodies what it means to coach the whole person, not just count macros.

  • With my dietitian, we worked on meal planning and building sustainable habits that fit my lifestyle. My labs have improved, my thyroid function has normalized, and my inflammation is now well-managed. I’m so grateful for her guidance and support throughout this journey—it has truly improved my quality of life.
