Policosanol
Long-chain alcohols from sugar cane wax with modest effects on LDL oxidation and platelet aggregation — cholesterol claims remain debated.
What the evidence says
Policosanol appears to help in 16 of 16 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 2005–2025 with a typical study size of 120 participants.

HighWhat the studies found
By outcome
Policosanol has an evidence score of 7.5/10 — strong evidence based on 36 indexed studies, including 7 meta-analyses. Long-chain alcohols from sugar cane wax with modest effects on LDL oxidation and platelet aggregation — cholesterol claims remain debated.
The commonly studied dose of Policosanol is 10-20mg daily. Research points to an estimated optimal dose around 20mg, with a minimum effective dose near 10mg. Individual response varies — start low and adjust.
The best time to take Policosanol is in the evening. Take it with food. Policosanol is a mixture of long-chain aliphatic alcohols (primarily octacosanol) derived from sugar cane wax.
Berberine
Likely helpsActivates AMPK to regulate blood sugar, improve insulin sensitivity, and support lipid metabolism — comparable to metformin in some trials.
Beta-Sitosterol
Likely helpsPlant sterol that reduces BPH urinary symptoms in clinical trials and blocks intestinal cholesterol absorption.

Policosanol is a mixture of long-chain aliphatic alcohols derived from sugar cane wax (Cuban policosanol), rice bran, or beeswax. Cuban studies showed dramatic cholesterol-lowering effects rivaling statins, but independent studies have failed to replicate these results. It may have modest effects on LDL oxidation and platelet aggregation. The discrepancy between Cuban and international studies remains unexplained.
May inhibit cholesterol synthesis
May reduce LDL oxidation
May reduce platelet aggregation

Cuban studies used sugar cane-derived form. Other sources may have different efficacy. Quality varies between products.
Minimum: 8 weeks
Optimal: 24 weeks

Note: Taking in evening aligns with peak cholesterol synthesis. Cuban studies used specific sugar cane-derived policosanol.
Effects highly inconsistent across studies with 80% showing mixed results. Cuban studies show better outcomes than non-Cuban studies. One large RCT (n=143) found no significant LDL reduction versus placebo. Only modest effects supported when present.
Possible modest LDL reduction
Reduced LDL oxidation
Studies show mixed results
Evidence is mixed; other options (berberine, red yeast rice) have stronger evidence
May have additive antiplatelet effects
Tip: Take with food
Policosanol is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are GI upset. Use caution if any of these apply to you: Known allergy or hypersensitivity to Policosanol or related compounds.
