Living With MTHFR | Mastering Nutrition #37

<p>MTHFR is an enzyme that allows folate (vitamin B9) to support the cellular process of methylation, which is important for the synthesis of creatine and phosphatidylcholine, the regulation of gene expression, neurotransmitter metabolism, and dozens of other processes. There are two common polymorphisms that decrease its activity, A1298C and C677T, with C677T having the stronger effect. Genetic decreases in MTHFR activity are associated with cardiovascular disease, neurologic and psychiatric disorders, pregnancy complications and birth defects, and cancer.</p> <p>While discussions of these polymorphism tend to focus on repleting methyl-folate, this should only be a small p...
