Cholesterol? Cholostrol is a common misspelling of cholesterol.
Cholesterol is a substance that your body needs in order to function properly. It holds cells together and assists your body in producing vitamin D, hormones, and substances that help you digest foods. Cholesterol comes from two places: your body (made in the liver) and the food you eat (animal products). Although your body needs cholesterol, too much of it can cause serious medical problems. Taking a blood cholesterol test is the only way to determine your cholesterol level.
