MTHFR methylation involves a gene that helps convert folate into a form the body can use for DNA repair, detoxification, and neurotransmitter production. Mutations in the MTHFR gene can impair this process, potentially leading to fatigue, mood disorders, or chronic illness. Proper nutrition and supplements may support methylation function. https://elementalhealthandnutrition.com.au/mthfr-methylation/
