Methylation is becoming relevant to more and more people who are trying to understand persistent fatigue, brain fog, poor concentration, sleep problems, mood changes, low stress tolerance, headaches, digestive difficulties, or simply an ongoing sense of not feeling well when routine testing has not provided a clear explanation. Others arrive at this topic through homocysteine, folate and vitamin B12 results, MTHFR findings, methionine, SAM, SAH, choline, TMG, or unexpected responses to supplements.

Yet the information available online is often fragmented, contradictory, and surprisingly easy to turn into a methylation rabbit hole. One laboratory marker may appear to point in one direction, a genetic finding in another, while diet, organ function, and supplement responses make the picture even harder to interpret.

I created this finder for people who already have some laboratory results, genetic information, diet or supplement history, but need a clearer sense of which direction may be most useful to explore first.

This finder is grounded in current peer-reviewed research and established biochemistry. Its questions and result logic are based on documented relationships between laboratory markers, nutrient availability, genetics, organ function, and one-carbon metabolism, rather than on generic symptom matching. Where the evidence is incomplete, the result is designed to show that uncertainty instead of presenting speculation as fact.

The finder may point toward one or several pattern directions, explain why they appeared, show what may be complicating the picture, and highlight which missing information could make the next step clearer.

It does not diagnose a condition or provide a treatment or supplement protocol. It is an educational tool designed to help you organize what you already know and find a more responsible starting point.
