MTHFR, COMT, and Methylation Testing: What Your Genes CaMTHFR is one of the most searched — and most misunderstood — topics in functional medicine. People arrive either terrifiedn (and Can't) Tell You

What a variant means. A common MTHFR variant can mean your body is somewhat less efficient at converting folic acid into its active form. A COMT variant can influence how you clear certain neurotransmitters and hormones, which is why some people with it are more sensitive to stress or to stimulation. These are tendencies, not diagnoses.

Here's the honest part — what these genes can't tell you. Having a variant does not mean you're sick, and it does not, by itself, explain fatigue, anxiety, or any specific condition. Genes load the gun; environment, diet, stress, and nutrient status pull the trigger. Plenty of people carry these variants and are perfectly healthy. Anyone selling you an expensive protocol based on a gene result alone is getting ahead of the science.

How we actually use it. We use MTHFR and COMT results as one input — a piece of context — alongside your symptoms, your history, and functional lab work like micronutrient and inflammatory testing. If a variant is relevant to your picture, it might inform the form of a nutrient we recommend (for example, an active form of folate rather than folic acid) or how we approach stress and detoxification support. It's a clue, not the whole case.

Who it tends to help most. People dealing with stubborn fatigue, mood or stress sensitivity, a family history that makes them curious, or those who've already "tried everything" and want to understand their biochemistry more precisely.

Testing details. Genetic testing is done once — your genes don't change — and we interpret it in the full context of your health, never in isolation. Lab costs are discussed up front.
