Selenium, the trace mineral is absolutely essential to anyone trying to lower their cholesterol. It is helpful in controlling cholesterol in 3 ways.
(1) It boost levels of glutathione (an antioxidant that prevents cell damage caused by free radicals.)
(2) Selenium works on its own to lower LDL
(3) It increases the helpful HDL

It is recommended by Philip Lee Miller, MD (Founder and Director of the Los Gatos Longevity Institute in California.) To take a Multivitamin Daily that contains at least 200 micrograms of selenium.
