Policosanol
Policosanol
TL;DR
Policosanol, a sugar-cane wax alcohol mixture, was once touted for cholesterol based on Cuban trials, but independent replication has largely failed — current evidence does not support it as a lipid-lowering agent.
Ideal For
- Almost no one, given failed replication of benefit
Avoid If
- You are using it as a substitute for proven lipid therapy
Frequently Asked Questions
Overview
The policosanol story is a cautionary tale in supplement evidence. Dozens of Cuban trials reported statin-like LDL reductions with excellent tolerability. However, when independent groups tested Cuban and non-Cuban policosanol using rigorous methods, lipid effects vanished: a 2006 JAMA trial (Berthold et al.) found no effect on LDL, HDL, or triglycerides across multiple doses. Hypotheses for the discrepancy include publication bias, product differences, and diet interactions, but none are proven. Small trials suggesting antiplatelet effects exist but are insufficient for clinical claims. Policosanol is safe and cheap, but consumers seeking LDL reduction should look to red yeast rice (with caveats), berberine, psyllium, or conventional therapy instead.
How It Works
- Proposed inhibition of cholesterol synthesis in the liver (mechanism never confirmed in humans)
- Possible AMPK activation in preclinical models
- Mild antiplatelet aggregation effects in small studies
- The originally claimed HMG-CoA reductase modulation has not been replicated
