What is MTHFR?
MTHFR is an enzyme made by your body that helps transform
folic acid (vitamin B9) into the form your body needs, L-methylfolate.
If you have an MTHFR gene variant, you cannot convert folic acid.
Without L-methylfolate, you may have elevated homocysteine levels,
inflammation, heart disease, birth defects, difficult pregnancies, miscarriages,
problems with your metabolism, and an impaired ability to detoxify.
More than half of the population may have the MTHFR gene variant.
Folic acid is the synthetic form of folate found in most supplements
and processed foods. People with the MTHFR gene variant have a
difficult time converting folic acid to the useful form, L-methylfolate.
Because this folic acid cannot be converted, it builds up in your body
and leads to toxicity, increasing your risk of cancer. Without the
ability to convert it to the useful form, your body cannot function well.
