There are two major types of cholesterol Ð LDL (low density lipoprotein) and HDL (high density lipoprotein).Ê LDL is the one doctor's worry about. High levels of LDL in the blood have been linked to health issues including heart attack and stroke. Plant Sterols offer a natural way to maintain a healthy cholesterol level. Taking at least 800mg plant sterols each day supports a healthy cholesterol. Taking 1500mg-3000mg per day can help to naturally reduce cholesterol levels.
