Policosanol is a natural supplement derived from sugar cane. The main ingredient is octacosanol. Octacosanol is an alcohol found in the waxy film that plants have over their leaves and fruit. The leaves and rinds of citrus fruits contain octacosanol, and so does wheat germ oil.
Policosanol has been shown to normalize cholesterol as well or better than cholesterol-lowering drugs, without side effects such as liver dysfunction and muscle atrophy.1 Efficacy and safety have been proven in numerous clinical trials, and it has been used by millions of people in other countries. Policosanol lowers harmful LDL-cholesterol and raises protective HDL-cholesterol. HDL-cholesterol removes plaque from arterial walls.
Policosanol helps stop the formation of artery lesions,2 an effect similar to that of statin drugs. This was proven in studies on rabbits fed a diet designed to create high cholesterol. According to researchers “in most policosanol-treated animals, atherosclerotic lesions were not present, and in others, thickness of fatty streaks had less foam cell layers than in controls.,3
Policosanol also inhibits the oxidation of dangerous LDL-cholesterol4 which promotes the destruction of blood vessels by creating a chronic inflammatory response. Oxidized LDL can also provoke metalloproteinase enzymes.5 These enzymes promote blood vessel destruction, partly by interfering with HDL’s protective effect. Studies show that rats treated with policosanol have fewer foam cells, reflecting less inflammatory response causing less blood vessel destruction.6,7
Healthy arteries are lined with a smooth layer of cells so that blood can race through with no resistance. One of the features of diseased arteries is that this layer becomes thick and overgrown with cells. As the artery narrows, blood flow slows down or is blocked completely. Policosanol can stop the proliferation of these cells in much the same was as lipid-lowering drugs.8,9
Policosanol also inhibits the formation of clots, and may work synergistically with aspirin in this respect. In a comparison of aspirin and policosanol, aspirin was better at reducing one type of platelet aggregation (clumping together of blood cells). But policosanol was better at inhibiting another type. Together, policosanol and aspirin worked better than either alone.10,11
Thromboxane is a blood vessel-constricting agent that contributes to abnormal platelet aggregation that can cause a heart attack or stroke. Significant reductions in the level of thromboxane occur in humans after two weeks of policosanol.12
People with elevated LDL-cholesterol (over 100) or low HDL-cholesterol (under 50) should seek to protect themselves from the potentially fatal effects of cardiovascular disease. Some people can achieve optimal cholesterol levels via dietary modification, while others require intervention with dietary supplements like policosanol or prescription drugs.
Some people will not achieve adequate results with policosanol or FDA-approved cholesterol-lowering drugs. That is why it is so important to have your blood tested when using policosanol (or FDA-approved drugs). Some people will only require 5 mg to 10 mg a day of policosanol, while others may need 20 mg/day. The same dosage variation may be true of cholesterol-lowering drugs.
