The philosophy

Normal isn’t the same as optimal. Standard bloodwork asks whether you’re sick. Functional labs ask how you’re functioning, and show what to do next.

Every plan starts with a conversation. From there, we test what matters and build from your results.

Hello, I’m Jennifer.

I’m a functional nutritionist focused on foundational health. For two decades I’ve helped clients understand their body’s unique needs through functional lab testing (metabolic panels, hormone testing, micronutrient analysis and gut health assessments) and personalized nutrition that turns that understanding into change that lasts.

Small habits add up to a lifetime of choices. Let’s find yours.

Questions, answered

Have one that isn’t here? Ask it on your free call.

What happens on the free call?

We talk through your health history, current symptoms, lifestyle and goals. If you have labs, I’ll walk you through what they show, and we’ll talk about which tests, if any, would help next. There’s no obligation.

Can you review labs I already have?

Yes. Bring what you have. Depending on what’s there, I may suggest one or two functional tests to fill in the picture.

How is functional testing different from standard bloodwork?

Standard ranges are built to flag disease. Functional testing looks at optimal ranges and at how your body’s systems work together, which can explain symptoms when you’ve been told everything looks normal.

How soon will I feel a difference?

Many clients notice changes within a few weeks of starting their protocol. Lasting change usually builds over three to six months, and every body’s timeline is different.

Do you treat medical conditions?

I don’t diagnose or treat medical conditions. I work with people who want to feel their best, often alongside their doctor, using nutrition and lifestyle.

How much does it cost?

It depends on the path that fits you, from a single lab review to ongoing coaching. We’ll find the right fit for your needs and budget on the free call.
