Methylation is a vital biochemical process in the body that relies on vitamins. It plays a crucial role in supporting various facets of both mental and physical health, including the regulation of gene expression. This intricate process takes place countless times every second and is responsible for ongoing DNA repair within the body. However, when methylation processes begin to decelerate, it can lead to an increased risk of DNA strand breakage. In addition to its pivotal role in DNA repair, methylation reactions also contribute to maintaining optimal neurotransmitter production, promoting a balanced homocysteine level for cardiovascular health, and facilitating the recycling of molecules necessary for detoxification and a healthy response to inflammation.
