Policosanol is a mixture of long-chain aliphatic alcohols that naturally occur in sugar cane. Over a decade of short-term and long-term clinical research involving thousands of subjects reveals the safety and tolerability of policosanol. The promising results of randomized, double-blind, placebo-controlled trials, including comparative studies, suggest that policosanol supports cardiovascular health. Though the mechanism for cardiovascular support of this substance remains unclear, policosanol may act in part by providing antioxidant protection, promoting healthy platelet function, and supporting healthy lipid metabolism. At the highest dosage recommended by Pure Encapsulations, policosanol may support healthy lipid metabolism in some individuals.^‡
