MTHFR vs Methylation?

They are not the same thing but they are related. MTHFR (Methylenetetrahydrofolatereductase) is an enzyme (by the genetic snp of the same name) that is essentially responsible for taking all the folate you eat and turning it into 5-methyltetrahydrofolate. Why do you care?

Methylfolate is very important for the Methionine Cycle.
