High-Density Lipoprotein (HDL) is known as the "good" cholesterol. HDL carries cholesterol from parts of the body to the liver, which then gets rid of it. HDL removes excess cholesterol from your blood and reduces buildup of cholesterol in the arteries.

Low-Density Lipoprotein (LDL) is known as the "bad" cholesterol. In normal amounts, LDL does an important job by carrying cholesterol from the liver, where it's made, to cells in the body. But too much LDL is bad and can stick to the walls of your arteries.
This causes a disease called atherosclerosis, where the artery walls become narrow, making it harder for blood to circulate. Having atherosclerosis raises the risk of heart attack or stroke. ¹

Triglycerides(TG) are the most common form of fat in the body. They're produced in the liver and also come from food. They are a major source of energy. Triglycerides are stored as fat, so if you regularly eat more calories than you burn off, triglyceride levels tend to rise. High levels of triglycerides carry a higher risk of health problems.¹
