Tocotrienols (Palm Tocotrienol-Rich Fraction · Annatto-Sourced)
Also known as: Palm TRF · Annatto tocotrienols · δ-tocotrienol · γ-tocotrienol
Mechanism of action
- Unsaturated isoprenoid side chain allows wider distribution into membrane lipids than α-tocopherol
- HMG-CoA reductase suppression at high doses (cholesterol pathway)
- NF-κB and STAT3 modulation in inflammatory contexts
Molecular + tissue targets
- Lipid profile (modest LDL-C effects)
- Oxidative stress markers
- Inflammatory cytokines
Dosage range
50-300 mg/day palm tocotrienol-rich fraction (TRF) — 2025 Nutrition Reviews systematic review (PMID 38916919) of 30 RCT (n = 2,646) supports benefits in inflammation and lipid peroxidation but emphasises the need for further standardisation on optimal dose, duration and formulation
Safety notes
Generally well tolerated at the typical 50-300 mg/day range; uncertain long-term safety at higher doses; potential interaction with statins (mechanism overlap on HMG-CoA reductase) — discuss with clinician for users on lipid-lowering therapy
