Functional Medicine Doctor in Jacksonville, FL

Short answer: functional medicine looks for the reason behind a symptom instead of only covering it up. At Meridian, our clinical team does this at two offices, Southside Jacksonville and Orange Park. We start with a 45 to 60 minute visit, test with DUTCH hormone testing, organic acids testing, and bloodwork, and work in order: gut first, then adrenals, then hormones.

Who comes to us for functional medicine

Most people find us after years of feeling off. The labs come back normal. The answer is another prescription, or "it's just stress." But the fatigue, the bloating, the brain fog, or the hormone swings are still there every day.

Functional medicine asks a different question. Not "what do we call this?" but "why is this happening, and what can we change?" Standard lab ranges are built to flag disease. They are wide. You can land inside every range and still feel terrible. The space between normal and optimal is where a lot of chronic symptoms live.

What we help with

  • Gut problems — bloating, gas, reflux, IBS, SIBO and SIFO, leaky gut, and food reactions
  • Fatigue and burnout — tired all day, wired at night, running on caffeine
  • Hormone symptoms — PMS, irregular cycles, PCOS, perimenopause, low libido, low testosterone
  • Thyroid concerns — including Hashimoto's
  • Autoimmune conditions — such as rheumatoid arthritis and lupus
  • Weight that will not move no matter what you try
  • Brain fog, poor sleep, anxious or low mood with a physical driver behind it

Gut first, then adrenals, then hormones

The order matters, and it is the part most people have never heard. If your gut is not breaking down and absorbing food well, or if there is overgrowth and inflammation, the rest of the body runs short on what it needs. Hormone and adrenal work tends to stall until the gut is in better shape.

So we work in sequence. We address digestion and the gut first. Then we support the adrenals and the stress response. Then we look at sex hormones. Doing it in this order is how we keep you from spending months on a hormone plan that was never going to hold. You can read more in our gut-first protocol.

The testing we use

We do not run every test on every person. We pick tests based on your history and symptoms, so the money you spend on labs answers a real question.

  • DUTCH hormone testing — a dried urine test you collect at home. It shows sex hormones, adrenal hormones like cortisol, and how your body processes them through the day.
  • Organic acids testing (OAT) — a urine test we use to look for signs of yeast and bacterial overgrowth, including SIBO and SIFO patterns, along with nutrient and energy markers.
  • Bloodwork — including a fuller thyroid picture, blood sugar, inflammation, and nutrient levels, depending on what your symptoms point to.

What your first visit looks like

  • Plan on 45 to 60 minutes. It is a real conversation, not a rushed appointment.
  • We go through when your symptoms started, what changed, what you have tried, your diet, sleep, stress, medications, and supplements.
  • We explain what we think is going on and which tests make sense for you, and why.
  • When results are back, we walk through every finding in plain language and build your plan around it.

Your first visit is in person at our Southside Jacksonville or Orange Park office. After that, many follow-ups, lab reviews, and check-ins can be done by video, so your plan does not depend on driving in every few weeks.

Looking for a holistic or natural doctor near you?

Many people who find us were searching for a holistic doctor, a natural doctor, or alternative medicine near them. What they usually want is the same thing: someone who listens, looks at the whole person, and finds the reason behind the symptoms instead of adding another prescription. That is exactly how functional medicine works at Meridian.

  • Whole-person care — your gut, stress, sleep, hormones, and how you move are looked at together, not one at a time
  • Testing that answers a question — DUTCH, organic acids, food sensitivity, genetic testing, and bloodwork, chosen for your symptoms
  • A natural-first plan — food, lifestyle, and targeted support, built in the order your body needs it
  • Care that works alongside your doctor — keep your physician and any prescribed medication, and we share what we find

Both offices are in the Jacksonville area: Southside Jacksonville near Baymeadows and Deerwood, and Orange Park for Clay County. Leave your number and our team will call you back, or start with the free gut and metabolic assessment.

Functional medicine and chiropractic under one roof

Meridian is a chiropractic practice too, and that matters more than most people expect. Healing an injury is a metabolic job. Rebuilding a strained muscle, a ligament or a disc takes protein, vitamins and minerals that your gut has to break down and absorb, and a stress and hormone system that lets your body switch into repair mode. When digestion, blood sugar or cortisol are off, recovery stalls. That is why our functional medicine program is part of how we get physical injuries better, not a separate service down the hall.

It is also what the "integrative" in Meridian Integrative Wellness means. We look at your body two ways at once: physically, how you move and carry load, and metabolically, how you turn food into energy and new tissue. Together, those two decide how long and how well you live. The research backs this up:

  • Fitness tracks with lifespan. In a Cleveland Clinic study of 122,007 adults followed for about 8 years, the least fit had roughly five times the risk of death of the most fit, and the researchers found no upper limit to the benefit (Mandsager et al., JAMA Network Open, 2018).
  • Strength counts. Across 139,691 adults in 17 countries, every 5 kg drop in grip strength came with about a 16% higher risk of death from any cause (Leong et al., The Lancet, 2015).
  • Daily movement adds up. Pooled data from 15 studies found the risk of death kept falling as daily steps rose, levelling off around 6,000 to 8,000 steps a day for adults over 60 and 8,000 to 10,000 for younger adults (Paluch et al., Lancet Public Health, 2022).
  • A healthy metabolism is rare. Only 6.8% of US adults had optimal heart and metabolic health in 2017 to 2018, judged on weight, blood sugar, cholesterol and blood pressure (O'Hearn et al., Journal of the American College of Cardiology, 2022).

Movement keeps the frame strong. A healthy metabolism feeds it. We work on both at the same time, with one team that talks to each other, so the results last.

Frequently asked questions

What does a functional medicine doctor do?

A functional medicine provider looks for the reason behind a symptom instead of only managing it. That means a long first visit about your history, targeted testing, and a plan built around what the testing shows. At Meridian that testing is DUTCH hormone testing, organic acids testing, and bloodwork.

Where can I find functional medicine in Jacksonville, FL?

Meridian Integrative Wellness offers functional medicine at two offices: 9770 Old Baymeadows Rd #139 in Southside Jacksonville, (904) 379-9412, and 1532 Kingsley Ave #102 in Orange Park, (904) 541-4826. Both are open Monday through Thursday 9am–7pm and Friday 8am–5pm.

Is a functional medicine provider the same as a holistic doctor?

They overlap. Holistic care means looking at the whole person. Functional medicine does that with a structured process: a long history, targeted testing like DUTCH, organic acids, and bloodwork, and a plan built in order, gut first, then adrenals, then hormones. At Meridian, that is the care you get when you search for a holistic or natural doctor in Jacksonville.

How long is the first functional medicine visit?

Plan on 45 to 60 minutes. We go through your full health history and symptoms, then explain which tests make sense for you and why.

Why do you treat the gut before hormones?

If the gut is not digesting and absorbing well, or there is overgrowth and inflammation, adrenal and hormone work tends to stall. So we work in order: gut first, then adrenals, then hormones.

What tests do you use for SIBO and SIFO?

We use the organic acids test (OAT), a urine test that shows markers of yeast and bacterial overgrowth, along with your symptoms and history.

Can I do functional medicine visits by video?

Your first visit is in person so we can do a full history and exam. After that, many follow-ups and lab reviews can be done by video.

Do I have to stop seeing my regular doctor?

No. Our care works alongside your physician. Keep taking any prescribed medication unless your prescriber changes it. We are happy to share what we find with your doctor.
