A hormone produced by the adrenal glands and a derivative of cholesterol. This is the building block to make estrogen, progesterone and testosterone. This hormone steadily declines as we age, in fact research has shown that we produce half of the DHEA in our 40’s as we did in our 20’s. Anyone over the age of 40 that wishes to protect themselves against cardiovascular disease and live longer, healthier lives should be taking DHEA.
