Policosanol
Sugarcane wax alcohols sold for cholesterol — but replication failed.
What is Policosanol?
Policosanol is a heart and metabolic supplement used for marketed to lower ldl cholesterol. NutriDex grades the human evidence as Mixed. Policosanol is a mixture of long-chain alcohols (mainly octacosanol) extracted from sugarcane or other plant waxes. More than 50 Cuban trials, nearly all from one research group tied to the maker Dalmer, reported striking lipid effects — LDL down 20–29%, HDL up 8–15% at 10–20 mg/day. But that consistency is itself suspicious, and rigorous independent trials told a different story: a 143-patient German multicenter RCT testing 10–80 mg found LDL fell less than 10% in every group with no difference from placebo, and smaller US and Canadian RCTs using authentic Cuban material also showed nothing. A separate research group in Korea (Cho and colleagues) more recently reported lipid and small blood-pressure benefits, but again as a single advocating group. Pooled blood-pressure meta-analysis shows a small ~3/1.5 mmHg drop. Overall the headline cholesterol claim has not survived independent replication.
Purported Benefits
Evidence by outcome
The same supplement can be well-proven for one use and unproven for another — here is the human evidence graded outcome by outcome.
| Outcome | Evidence | Effect | Studies |
|---|---|---|---|
| Lower LDL cholesterolHuge single-source Cuban effects failed independent replication; rigorous RCTs showed no LDL change. | Mixed | ↔ mixed | 3 |
| Raise HDL cholesterolHDL gains come only from advocating groups; independent RCTs found no lipid effect. | Mixed | ↔ mixed | 2 |
| Lower blood pressureMeta-analysis suggests ~-3.4/-1.5 mmHg, but trials overlap with single-source advocating groups. | Preliminary | ↑ benefit · small | 2 |
