Genomic Testing and Nutrigenomics in Branford, CT

What if I could see how your body actually processes nutrients, manages inflammation, metabolizes hormones, and handles toxins — before recommending a single supplement or dietary change? That's what genomic testing allows me to do, and it's one of the most powerful tools in my practice.

I'm Dr. Tavernier, and I use 3x4 Genetics clinical testing at Tantien Integrative Medicine because I believe the era of one-size-fits-all medicine should be over. Your body is not average, and your care plan shouldn't be either.

What Is 3x4 Genetics Testing?

3x4 Genetics is a clinical genomic test designed for healthcare practitioners — it's fundamentally different from consumer tests like 23andMe or AncestryDNA. Those tests give you interesting data but very little clinical direction. 3x4 is built for clinical decision-making. It analyzes over 134 genes across 36 metabolic pathways, and — this is what makes it valuable — it examines how your genes interact with each other, not just in isolation.

The test itself is simple. It's a cheek swab that can be collected in my office or at home. Results are returned in a detailed clinical report that I review with you line by line and use to inform your personalized care plan.

What Your Genomic Report Reveals

Your 3x4 report covers how your body processes and utilizes specific nutrients, how efficiently your detoxification pathways function — including Phase I and Phase II liver detoxification, methylation, and glutathione production, your genetic inflammatory profile and how your body responds to oxidative stress, how you metabolize hormones, particularly estrogen and cortisol, your cardiovascular risk profile at the genetic level, how your body responds to different types of exercise and recovery, caffeine metabolism, lactose and gluten sensitivity markers, and your predisposition for specific vitamin and mineral deficiencies.

What Is Nutrigenomics?

Nutrigenomics is the study of how your genes interact with the foods you eat. It's the reason your friend thrives on a high-fat diet while it makes you feel terrible, or why the supplement protocol your sister swears by does absolutely nothing for you.

Through genomic testing, I can identify your specific nutritional needs and build dietary and supplement recommendations that are matched to your DNA. This isn't a trend — it's the future of personalized medicine, and it's available now.

How I Use Genomic Testing in Your Care

I want to be clear: genomic testing is not a standalone service at Tantien Integrative Medicine. I don't hand you a report and wish you well. It is one layer of a comprehensive integrative evaluation. I combine your genomic data with your full health history, your current symptoms, your lifestyle, your environment, and your conventional lab work to build a care plan that sees your whole picture.

Here's a practical example. If your genomic profile shows impaired methylation and slow Phase II detoxification, and you've come to me with brain fog and chronic fatigue, I can connect those dots. I can recommend specific forms of B vitamins your body can actually use, dietary changes that support your detox pathways, and lifestyle modifications that reduce the toxic load your body is struggling to process. That's a very different conversation than "take a multivitamin and get more sleep."

Who Benefits from Genomic Testing?

In my experience, genomic testing is valuable for patients dealing with chronic conditions who want to understand why their body responds the way it does, for individuals with a family history of heart disease, cancer, diabetes, or autoimmune conditions who want a proactive prevention strategy, for patients who have tried multiple diets, supplements, or protocols without results and are tired of guessing, and for health-conscious individuals who want to optimize their nutrition, exercise, and lifestyle choices based on their own biology rather than general population guidelines.

Your Genes Are Your Roadmap — Not Your Destiny

I tell every patient this: a genetic variant is not a sentence. It's information. It shows me where your body may need extra support and where your natural strengths lie. The goal is to shift your medicine from reactive — waiting for disease to develop — to proactive — understanding your vulnerabilities and addressing them before they become problems.
