Policosanol is a natural supplement derived from sugar cane wax that is commonly used for lowering cholesterol levels. It works by inhibiting the synthesis of cholesterol in the liver, and also by increasing the breakdown of cholesterol in the body. Policosanol has been found to be effective in reducing total cholesterol, LDL (“bad”) cholesterol, and triglycerides, while raising HDL (“good”) cholesterol. The typical dose of policosanol is 10-20 mg daily, although higher doses may be necessary in some cases.
Policosanol is a waxy substance derived from sugar cane wax, wheat germ, and other sources [1, 2]. It's a popular supplement taken for various reasons, but the evidence for its effectiveness is mixed. Here's a breakdown of what we know about policosanol:
Potential Uses:
- Intermittent Claudication: This condition causes leg pain when walking due to poor blood circulation in the arteries. Some studies suggest policosanol might improve walking distance in people with intermittent claudication [1, 3].
- High Cholesterol: Research on policosanol's effectiveness for lowering cholesterol has yielded inconsistent results. Some studies show a modest decrease in LDL ("bad") cholesterol and an increase in HDL ("good") cholesterol, while others haven't found significant benefits [2, 4].
Important Considerations:
- Limited Strong Evidence: While some studies show promise for specific uses, more high-quality research is needed to confirm policosanol's effectiveness for various conditions.
- Dosage and Safety: There is no universally recommended dose of policosanol, and its long-term safety is not fully established. It's best to consult with a doctor before taking policosanol to determine the appropriate dosage and discuss potential risks and interactions with other medications.
- Alternatives: There are well-established and effective medications for treating intermittent claudication and high cholesterol. If you're considering policosanol, discuss these options with your doctor to determine the best course of treatment for you.
Additional Points:
- Policosanol is generally well-tolerated, but some people may experience mild side effects like diarrhea, nausea, and stomach upset [2].
- It's crucial to remember that policosanol is a supplement and not a regulated medication. The quality and content of policosanol supplements can vary.
