As much as 40% of the population may have genetic weaknesses that can result in an inability to properly coordinate how the body performs an important chemical function known as methylation. Proper methylation is critical to maintain healthy genetic function and can impact nervous, immune, and cardiovascular health. Dr. Peter D'Adamo designed the Methylation Stack to provide the basic nutrients required to help ensure proper biochemical function. This stack includes Methyl 12 Plus and Exakta which when taken together help the body to optimize this critical pathway.
