Cholesterol plays a vital role in various bodily functions, including energy storage, cell membrane formation, and hormone production.

HDL cholesterol helps remove excess cholesterol from the arteries and transport it back to the liver for removal from the body.

LDL cholesterol carries cholesterol from the liver to cells throughout the body.

High levels of LDL cholesterol can lead to the buildup of plaque in the arteries, increasing the risk of heart disease and stroke.

For adults, an LDL cholesterol level below 100 mg/dL is considered optimal for cardiovascular health.

VLDL cholesterol transports triglycerides from the liver to other tissues in the body.

For adults, an HDL cholesterol level above 60 mg/dL is considered optimal for cardiovascular health.
