About Sugar cane wax alcohols
Policosanol is a mixture of long-chain primary aliphatic alcohols (predominantly octacosanol, ~60–70%) extracted from sugar cane wax, with rice bran and beeswax used as alternative sources. Cuban research groups (Dalmer Laboratories) published numerous trials in the 1990s–2000s reporting LDL reductions of 15–25% at 5–20 mg/day, comparable to low-dose statins. However, virtually every well-controlled independent replication outside Cuba has failed to reproduce these effects: Berthold et al. (JAMA 2006) tested 10/20/40/80 mg/day vs placebo over 12 weeks and found no impact on LDL, HDL, or triglycerides; Cubeddu et al. (2006), Dulin et al. (2006), and Marinangeli et al. (2010 meta-analysis) reached the same null conclusion. The mechanism — proposed inhibition of hepatic cholesterol biosynthesis upstream of HMG-CoA reductase — has never been convincingly demonstrated in human studies. Generally well tolerated; mild antiplatelet activity warrants caution with anticoagulants. No established RDA/UL.
What Sugar cane wax alcohols supports
- Marketed for cholesterol support, but independent trials have not confirmed efficacy
How much Sugar cane wax alcohols to take
Clinical studies typically use 5–20 mg of Sugar cane wax alcohols. Cuban trials used 5–20 mg/day. Independent (non-Cuban) replications at 10–80 mg/day show no lipid effect, so the upper bound reflects the studied range, not a confirmed therapeutic threshold.
- Effective range
- 5–20 mg
Clinical evidence
Limited clinical evidence. Cuban-source trials reported strong LDL reductions; independent non-Cuban replications (incl. Berthold 2006 JAMA) consistently null
