 D.Anti-Inflammatory Formulation Clinical Studies

These clinical studies show that delta-tocotrienol in combination with antioxidant polyphenols curb inflammation and manage dyslipidemia. One of the placebo-controlled studies was conducted in two groups of elderly subjects, one with normal and the other with elevated lipid levels. The product formulation was composed of delta-tocotrienol from annatto, along with a B-vitamin (niacin) and polyphenols. In both groups, supplementation led to a significant drop in C-reactive protein (a predictor for chronic inflammation) and γ-glutamyl-transferase (a predictor for non-fatal myocardial infarction and fatal coronary heart disease), while increasing total antioxidant status, a measure of the body’s capacity to counteract reactive oxygen species. In the hypercholesterolemic group, LDL cholesterol (20-28%) and triglycerides (11-18%) also dropped. C-reactive protein dropped in healthy elderly (21-29%) as well as lipidemic elderly (31-48%), as did γ-glutamyl-transferase (14-20%). Notably, there were no adverse effects associated with the 6-week supplementation period.

An open-label randomized trial involving DeltaGold (125, 250, 500, 750, and 1,000 mg/d dosage groups) confirmed the bioavailability of tocopherol-free annatto tocotrienol. Delta- and gamma-tocotrienols are readily bioavailable if taken with a meal.
