Chronic Fatigue in Branford, CT

You've had the bloodwork. Your thyroid is "fine." Your iron is "within range." You've been told to sleep more, exercise, drink more water, maybe try an antidepressant. But the fatigue doesn't lift. It's not regular tiredness — it's the kind that sleep doesn't fix, that makes thinking feel like wading through concrete, that has quietly taken over your life.

I'm Dr. Tavernier, and I want you to know something important: if you feel this way, something is wrong. It may not show up on the tests your doctor has run so far, but that doesn't mean it isn't real. It means no one has looked deeply enough yet.

What I Mean by Chronic Fatigue

Chronic fatigue is one of the most common reasons patients come to see me. Some have a formal diagnosis of Chronic Fatigue Syndrome (CFS/ME). Others have persistent, crushing exhaustion that doesn't fit neatly into any diagnostic box — which usually means they've been dismissed, told it's stress, or quietly given up on getting answers.

I treat both. And I don't start by handing you a prescription. I start by asking why.

What Might Actually Be Causing Your Fatigue

Fatigue is not a diagnosis — it's a symptom. And it can have many drivers, most of which a standard 10-minute office visit doesn't have time to explore. In my practice, I investigate the factors that are most often overlooked.

These may include mitochondrial dysfunction — your cells aren't producing energy efficiently. Hidden infections such as Lyme disease, reactivated Epstein-Barr virus, or other chronic infections that quietly drain your immune system. HPA axis dysregulation — your stress response system has been running on high for so long that it's burned out. Gut dysfunction, including SIBO, intestinal permeability, or microbiome imbalance, all of which can steal nutrients and drive systemic inflammation. Nutrient deficiencies that standard labs don't catch or don't flag — B12, iron, magnesium, CoQ10, vitamin D. Hormonal imbalances, particularly thyroid, cortisol, and sex hormones. Methylation impairments, such as MTHFR variants, that affect how your body processes essential B vitamins and clears toxins. Chronic inflammation from autoimmune activity, dietary triggers, or environmental exposures. Sleep architecture disruption — you may be sleeping eight hours but not reaching the restorative stages your body needs. And toxic burden from mold, heavy metals, or environmental chemicals your body can't clear efficiently.

Most of my fatigue patients don't have one cause. They have three or four interlocking factors that no one has connected before.

How I Investigate

Your first visit with me is 90 minutes. I take a thorough history — not just your symptoms, but your sleep patterns, your stress load, your nutritional habits, your environmental exposures, and the full timeline of when and how your fatigue developed. I'm listening for patterns, for connections, for the things that a rushed appointment would miss.

From there, I may order advanced laboratory work that goes beyond what your primary care doctor has tested. I use 3x4 Genetics clinical testing to understand how your body produces energy, processes nutrients, manages inflammation, and detoxifies at the genetic level. I evaluate thyroid and hormones comprehensively — not just TSH. I assess for hidden infections, immune dysfunction, and gut health. And I look at your toxic burden and your body's capacity to handle it.

Your Treatment Plan

What I prescribe depends entirely on what I find. There is no generic fatigue protocol in my practice. Your plan is built around your biology and may include targeted nutritional therapy and anti-inflammatory dietary changes, supplementation matched to your genomic and lab results, hormone optimization when indicated, gut restoration, stress management and mind-body medicine, sleep optimization, breathwork and nervous system regulation through The Functional Living Method™ with Nicole Tavernier, and conventional referrals or prescriptions when they're the right tool.

I use the least invasive approaches first, and I work with your existing doctors — not against them.

About My Practice

I am a medical doctor with 34 years of clinical experience and fellowship training from the Andrew Weil Center for Integrative Medicine at the University of Arizona. I founded Tantien Integrative Medicine in Branford, CT, because I believe medicine should treat the person — not just the lab results. We are a cash-pay practice serving the Connecticut Shoreline and Greater New Haven area, and our model gives me the time to do this work properly.
