MTHFR is a gene that provides instructions for an enzyme involved in processing folate and, indirectly, regulating homocysteine levels. This genetic test looks for common variants in the MTHFR gene that can reduce enzyme activity, which in some people is associated with mildly elevated homocysteine levels, particularly when folate intake is also low. While MTHFR variants are common and testing is popular in some wellness and integrative medicine contexts, most major medical guidelines don't recommend routine MTHFR testing, since the variants alone have limited proven clinical significance for most people, and any related homocysteine elevation is better addressed by simply checking and, if needed, treating homocysteine and folate directly.
