Policosanol
Long-chain alcohols from sugar cane wax with modest effects on LDL oxidation and platelet aggregation — cholesterol claims remain debated.
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
Cycling: Not required
Note: Taking in evening aligns with peak cholesterol synthesis. Cuban studies used specific sugar cane-derived policosanol.
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
