MTHFR is an enzyme that adds a methyl group to folic acid to make it usable by the body. The MTHFR gene produces this enzyme that is necessary for properly using vitamin B9 and is also important for converting homocysteine into methionine, which the body needs for proper metabolism and muscle growth and which is needed for glutathione creation . The process of methylation also involves the enzyme from the MTHFR gene, so those with a mutation may have trouble effectively eliminating toxins from the body.
In this podcast, Dr. Paul Anderson answers the questions: What is methylation, how does it relate to the MTHFR defect and how does this affect our health? (Source: Contact Talk Radio)
