Cholesterol is a type of fat in the blood. Too much of this fat can add to a build-up of plaque in the blood vessels. It can raise your risk of stroke and heart disease.
Changes to diet, activity level, and medicine may help to lower levels. Some look to natural treatments to further lower their cholesterol.
These therapies are likely effective:

Herbs and Supplements to Be Used With Caution
Talk to your doctor about all herbs or supplements you are taking. Some may interact with your treatment plan or health conditions.
Niacin in large amounts may cause liver problems, gout, ulcers, problems seeing, high blood sugar, irregular heartbeat, and other health problems. It may also increase your risk of diabetes.
