Tocotrienol Supplementation Improves Lipid Profiles in Chronic Hemodialysis Patients

Scientists have found tocotrienol supplementation lower plasma triglyceride levels in patients undergoing chronic hemodialysis. The study was conducted by Professor Pramod Khosla’s group in Wayne State University. End-stage renal disease patients on chronic (at least 3 months prior to the study) dialysis treatment were recruited from a local dialysis clinic in Detroit. 81 Patients were randomized to receive either 180 mg tocotrienol rich fraction or placebo daily for 16 weeks. The patient compliance was measured by pill counting. After 12 weeks supplementation, the group receiving tocotrienol supplementation have decreased plasma triglyceride levels from 144 ± 91mg/dL to 113± 47 mg/dL (p <0.05). The triglyceride levels remained low (103± 45 mg/dL) at week 16. In the control group, the plasma triglyceride levels were unchanged. Triglycerides are produced from energy sources like carbohydrates. High plasma triglyceride levels (> 150 mg/dL) indicate increased risk of cardiovascular diseases. In end-stage renal disease patients, dyslipidemia is highly prevalent with elevated plasma triglyceride levels. This study indicated the lipid-regulation and potential cardio-protection effect of tocotrienol in these patients. The triglyceride-lowering effect of tocotrienol observed in this clinical study agrees with a previous publication by Davos Life Science, in which supplementation with 120 mg γδ-tocotrienol in 10 hypercholesterolemic subjects for 8 weeks led to a 28% reduction in plasma triglyceride levels. Both the tocotrienol supplementation group and the control group have decreased levels of total cholesterol, higher levels of high density lipoprotein cholesterol (HDLC) and decreased levels of low-density lipoprotein cholesterol (LDLC) at week 16. This could be due to the effect of the cholesterol-lowering drug statin of which 30-40% of the patients were taking concurrently. This study reinforced the cardiovascular benefits of palm-derived tocotrienols in lowering triglyceride levels in subjects with mild to moderate dyslipidemia.
