The MTHFR gene codes for the enzyme that converts folate into the form that your body needs in the methylation cycle (methylfolate). There are two main SNPs that have been shown to decrease the efficiency of the MTHFR enzyme. For both of these, it is important to make sure you get plenty of folate-rich foods in your diet. Good sources of folate include dark leafy greens, legumes, broccoli, and liver.

*SNP stands for Single Nucleotide Polymorphism, which is when one of the nucleotide bases (the A, C, G, or Ts) is replaced by a different nucleotide base in a gene.
