Minerals for the Genetic Code by Charles Walters & Dr. Richard Olree:
"Magnesium & selenium keep the genetic structure flowing. Selenium keeps the viruses OUT of your system. Selenium keeps your brain working. Selenium keeps your thyroid working. Magnesium keeps the electricity in the heart going. Magnesium keeps your kidneys regulated. Magnesium keeps the arteries from allowing calcium to penetrate into the arteries causing hardening of the arteries".
