Policosanol – a mixture of substances from a group of aliphatic alcohols derived from plant waxes. Its sources include, among others, coconuts, rice bran, sugar cane and beeswax.
It is used in supplementation mainly due to its ability to optimise the lipid profile. Studies conducted in Cuba, in which therapeutic properties of this mixture were discovered, indicate that regular administration of policosanol may reduce cholesterol concentrations even by 20%. In addition, it is capable of improving the HDL:LDL ratio by increasing levels of “good” HDL cholesterol and lowering levels of “bad” LDL cholesterol. Such effects were observed in daily doses of 20 mg.
Even though the latest studies show less positive effects of taking policosanol, they highlight still its important feature, which is safety of use.
