Magnesium is one of seven essential minerals that is crucial for the body's function. It plays a role in over 600 enzyme reactions in the body. Magnesium can be found in bones, muscles, soft tissues, and bodily fluids. It is estimated that 50-90% of people are deficient. This is due to the lack of magnesium in many diets including "the Standard American Diet", as well as a world with chronic stress. Common signs of magnesium deficiency include muscle stiffness or twitching, chronic irritability, increase in blood pressure, increase in inflammation and poor blood sugar control.
