Red yeast rice might be dangerous
Another popular cholesterol-lowering supplement is red yeast rice. There is some evidence that red yeast rice can help lower your LDL cholesterol. However, the Food and Drug Administration has warned that red yeast rice products could contain a naturally occurring form of the prescription medication known as lovastatin.
Lovastatin in red yeast rice products is potentially dangerous because there's no way to know how much lovastatin might be in a particular product. And there's no way to determine the quality of the lovastatin.
Garlic might be ineffective
Garlic is one of the best-known supplements for reducing cholesterol. Earlier studies on garlic produced conflicting results, but some indicated that garlic might lower cholesterol. However, more recent research has shown no evidence of cholesterol-lowering benefits.
Medications might be necessary
Sometimes, despite making healthy lifestyle choices and taking supplements and other cholesterol-lowering products, you still need help lowering your cholesterol levels. If your doctor prescribes medication to reduce your cholesterol, take it as directed while you continue to focus on a healthy lifestyle.
As always, be sure to tell your doctor if you decide to take a supplement. The supplement you choose might interact with other medications you take.
