Cholesterol is a waxy, fatty substance (lipid)

Cholesterol is produced by the liver and is in some foods. It is vital for normal body functioning and exists in the outer layer of every cell in our body. Cholesterol is transported in the blood. Not all cholesterol is harmful; there is ‘bad’ cholesterol and ‘good’ cholesterol.


If extra cholesterol builds up in your blood vessels over time, it can lead to narrowed or blocked arteries, which can cause heart attacks or stroke.
  • LDL-Cholesterol (low density lipoprotein) - Often called ‘bad’ cholesterol, LDL delivers cholesterol from the liver to your cells. Too much LDL in your blood is harmful and may increase your risk of arterial heart disease.
  • HDL-Cholesterol (high density lipoprotein) - Often called ‘good’ cholesterol, HDL may help reduce your risk of arterial heart disease.4 HDL takes cholesterol away from the cells and back to the liver, where it is either broken down or expelled from the body as waste.4
  • Triglycerides - Triglycerides are the way most fat exists in the body and in the blood. They are produced from the food we eat. Triglycerides enable our bodies to store unused energy from food (as fat) for later use. High levels of triglycerides in your blood put you at higher risk of heart disease, diabetes and stroke.
