Policosanol is a mixture of long-chain alcohols commonly extracted from sugarcane wax and sold as a supplement to lower cholesterol. Early studies suggested benefit, but later trials and reviews produced mixed results. Typical supplement doses range around 5-20 mg/day, and measurable changes - if any - often appear after 6-12 weeks. Speak with a clinician before adding policosanol, especially if you take prescription lipid-lowering drugs.

What policosanol is

Policosanol is a mixture of long-chain alcohols originally extracted from sugarcane wax. Manufacturers also source similar mixtures from rice bran wax and beeswax. Supplements marketed as policosanol typically aim to support healthy blood lipid levels.

How it might work

Researchers have proposed several mechanisms: modest inhibition of cholesterol synthesis, reduced LDL oxidation, and improved clearance of LDL particles. The exact mechanism is not fully established and likely varies with the product composition and dose.

What the clinical evidence shows

Early studies - many from Cuban research groups - reported reductions in total cholesterol and LDL cholesterol. Later trials and systematic reviews outside Cuba have produced mixed results, with some showing smaller or no effects. Overall, the evidence is inconsistent: some randomized trials report modest LDL reductions, while others find no benefit compared with placebo or standard treatments.

Most trials were small and used different policosanol preparations, which makes comparison difficult. Large, high-quality randomized controlled trials are limited, and meta-analyses have reached different conclusions depending on which studies they included. 1

Typical dosing and timeline

Over-the-counter policosanol supplements commonly provide doses in the 5-20 mg/day range. Some studies used single daily doses of 10-20 mg. Users who see an effect typically note changes in lipid tests after 6-12 weeks, but results vary. Consult a clinician before starting any lipid-lowering supplement. 2

Safety and interactions

Policosanol is generally reported as well tolerated in trials, with gastrointestinal complaints and headaches among the most commonly reported issues. Serious adverse events are uncommon in published studies, but long-term safety data remain limited. If you take prescription lipid-lowering medications (for example, statins), ask your doctor before adding policosanol; possible interactions or overlapping effects need clinical oversight.

Practical guidance

If you consider policosanol, treat it as a complementary approach rather than a substitute for proven therapies when you have high cardiovascular risk. Lifestyle measures - diet, weight management, and physical activity - have the strongest evidence for improving lipids and cardiovascular outcomes. Use supplements from reputable manufacturers and discuss them with your healthcare provider, especially if you have liver disease, take other medications, or have established heart disease.

Bottom line

Policosanol is a sugarcane-derived supplement with a history of research on cholesterol. Evidence is mixed: some studies report modest LDL lowering, but larger, independent trials are inconsistent. Consult a clinician to decide whether policosanol fits your individual risk profile and treatment plan. 3
  1. Verify the current state and conclusions of systematic reviews/meta-analyses on policosanol (post-2006) and whether large independent trials exist.
  2. Confirm commonly used supplement dose ranges (typical 5-20 mg/day) from product labels and clinical trials.
  3. Confirm reported timelines for lipid changes (6-12 weeks) across trials.
  4. Check the claim about early Cuban studies and the size/scale of those trials.

FAQs about Policosanol

Does policosanol lower LDL cholesterol?
Some trials report modest LDL reductions, but overall evidence is inconsistent. Results vary by study quality, dose, and the source/preparation of policosanol.
How long before policosanol works?
Studies that report an effect generally show changes within 6-12 weeks, but individual responses vary and not everyone sees benefit.
Is policosanol safe?
Policosanol is generally well tolerated in short-term trials; common mild side effects include gastrointestinal upset and headache. Long-term safety data are limited, so consult your clinician before use.
Can I take policosanol with a statin?
You should discuss this with your healthcare provider. Combining supplements with prescription lipid-lowering drugs requires medical oversight to monitor effectiveness and potential interactions.
Where does policosanol come from?
Policosanol preparations are usually extracted from sugarcane wax, but similar mixtures can come from rice bran or beeswax.
