Genetic testing in functional medicine shows how your body methylates, detoxifies, and responds to nutrients and medications. That lets us fit treatment to you instead of guessing.
One-size-fits-all medicine ignores the code you were born with. Here is how we use yours.
What Genetic Testing Can Reveal
Certain gene variants change how your body runs day to day.
- Methylation. Variants like MTHFR affect how you process B vitamins and folate.
- Detox pathways. Some people clear toxins and hormones more slowly than others.
- Hormone metabolism. How your body breaks down estrogen can matter for symptoms and risk.
- Inflammation. Some variants keep the inflammatory response running hotter.
- Nutrient needs. You may need more of a vitamin, or a different form of it.
- Medication response. Some genes predict which drugs work well for you and which cause side effects.
None of these are diagnoses. They are clues about how your biology runs.
A Closer Look at Methylation
Methylation is a chemical process your body performs billions of times a day. It helps build DNA, make brain chemicals, and clear out used hormones.
If you carry a common MTHFR variant, you may convert folic acid to its active form less efficiently. That does not make you sick by itself. But it can mean a standard multivitamin is not doing much for you, and that a methylated form of folate and B12 works better.
This is a good example of how a gene result changes something practical: not whether you take a vitamin, but which form you take.
Medication Response
Pharmacogenetics looks at how you process medications. Some people break a drug down so fast that a normal dose does nothing. Others break it down slowly and get side effects at a dose most people tolerate.
As a pharmacist, this is an area I pay close attention to. Knowing this ahead of time can save you months of trying medications that were never going to suit you.
How We Use It, and How We Do Not
Genes are not destiny. Most variants only matter when they meet the right diet, stress level, or exposure. Your habits still carry more weight than your genome.
We read your results alongside your labs and your symptoms. Genetics helps explain stubborn patterns and personalize your plan: which forms of nutrients suit you, which detox support makes sense, and which medications to favor or avoid.
What we never do is sell fear based on a gene report. You will not leave with a list of frightening variants and a cart full of supplements. If a result does not change your plan, we will say so.
Who Should Consider Testing
Genetic testing tends to be most useful if you:
- Have not responded to treatment that should have worked
- React badly to many medications or supplements
- Have a strong family history of a condition you want to get ahead of
- Have stubborn fatigue, brain fog, or hormone symptoms with unclear causes
- Want a more precise plan rather than trial and error
It is not something everyone needs. For many people, standard labs and a careful history answer the question first.
What the Process Looks Like
Testing is usually a cheek swab or saliva sample you collect at home and mail in. Results take a few weeks.
The results themselves are not the valuable part. The interpretation is. A raw gene report will list dozens of variants with no sense of which ones matter for you. We go through it together and turn it into a short list of changes worth making.
Your genes do not change, so this is a one-time test you can use for the rest of your life.
Privacy and Your Data
People ask, reasonably, what happens to their genetic information. Consumer ancestry companies and clinical testing are not the same thing, and their policies differ.
Before we order anything, we tell you which lab is used, what they do with your sample, and what their data policy says. If you are not comfortable with it, we do not order the test.
What It Costs and Whether It Is Worth It
Genetic panels are typically a few hundred dollars and are usually not covered by insurance. It is a one-time cost for information you keep for life.
Whether it is worth it depends on your situation. If standard labs have already explained your symptoms and treatment is working, it probably is not. If you have been through several failed treatments, it often pays for itself in avoided trial and error.
