MTHFR & genetics
If you've ever been told "you have MTHFR," you probably left the appointment with more questions than answers. MTHFR — short for methylenetetrahydrofolate reductase — is an enzyme that turns the folate you eat into 5-MTHF, the form your cells actually use. When a common variant slows that conversion, it ripples outward: homocysteine rises, methylation slows, and downstream pathways for mood, sleep, detoxification, and pregnancy all have to compensate.
This hub is the starting place. The articles below explain what MTHFR is, which variants matter most (C677T and A1298C are the two you'll see flagged), how to test, what the symptoms look like in the carriers who notice them, and what the research says about supplement choice. If you've just received test results or are considering a nutrigenomics panel, read "What is MTHFR?" first, then work outward to the topics most relevant to your situation — pregnancy, homocysteine, or symptom management.

MTHFR variants don't cause a single recognizable disease. They shape how you feel on an ordinary Tuesday — energy, mood, sleep, tolerance for caffeine and alcohol. Here's what carriers actually describe.

Your genes are fixed. How they behave is not. Epigenetics is the layer of control that diet, stress, and lifestyle write onto DNA over a lifetime — and here's what the research shows you can actually change.

MTHFR carriers don't need to avoid supplements wholesale — but a handful of common ingredients actively work against impaired methylation. Here's the practical list, the biology behind each one, and what to swap them for.

Nutrigenomics is the study of how your genes shape what you eat — and what you absorb. Here's what the field actually tells us, which variants have enough evidence to act on, and how to translate a DNA panel into a real supplement protocol.

There are three realistic ways to test for MTHFR — single-gene panel, comprehensive nutrigenomics, or consumer kit. Here's how each works, what they cost, and what the results actually tell you.

MTHFR is one of the most studied — and misunderstood — genes in nutrition science. Here's what it actually does, which variants matter, and what it means for your supplement stack.

Homocysteine is the single most useful functional marker for methylation status. Here's what it is, why MTHFR carriers watch it closely, and what the numbers mean for cardiovascular, cognitive, and pregnancy risk.

Consumer genetic reports list hundreds of SNPs. Only a handful have the evidence to change what you eat or supplement. Here are the ones with enough clinical weight to act on.

MTHFR variants affect folate metabolism during pregnancy — the window with the highest folate demand in human biology. Here's what the evidence says about bioactive folate, recurrent pregnancy loss, and the prenatal choices that actually matter.
