Studies have shown that DNA synthesis is slowed by insufficient magnesium. (1), (3) DNA, or deoxyribonucleic acid, is the body’s genetic code, used in the building of proteins and the reproduction of cells. The cells in our body are constantly being replaced by new cells. Different types of cells turnover at different rates, with the average age of a cell in the human body estimated at seven years.
Studies have shown that DNA synthesis is slowed by insufficient magnesium.
Thus, it is especially important that our DNA remain stable, avoiding mutations that can negatively impact cellular function.
DNA stability is dependent in part on magnesium. Magnesium not only stabilizes DNA structures, it also functions as a cofactor in the repair of DNA damage by environmental mutagens. (4) Combined with ATP, magnesium also assists in the healthy production of RNA, responsible for “reading” DNA and manufacturing the proteins used in our body.
