What each result means

C/C Typical MTHFR enzyme activity in published research.
C/T Published research associates this genotype with somewhat reduced MTHFR enzyme activity.
T/T Published research associates this genotype with meaningfully reduced MTHFR enzyme activity, which can affect how folate is processed.
Talk to a doctor or a registered dietitian about folate intake, especially if you are planning a pregnancy.
