Delta-tocotrienol (δ-T3) are beneficial for lipid metabolism. However, there are almost no reports on the specific numerical values of changes in blood tocotrienol levels when Japanese people consume tocotrienol. To observe the effect on blood δ-T3 and lipid concentrations after taking δ-T3, a crossover test was conducted with a control group, alpha-tocopherol (α-TP) group (264 mg/day), and δ-T3 group (250 mg/day). Participants took the target supplements for 14 days. This study revealed that plasma δ-T3 concentrations in healthy men and women increased significantly even with short-term intake (pre; 0.11 ± 0.03 to post; 0.40 ± 0.19 μmol/L). The results of this study showed that α-TP and δ-T3 intake did not significantly affect any of the lipid profiles. However, the intake of δ-T3 tended to increase Low-density lipoprotein cholesterol (HDL-C) levels (pre: 59 ± 17 to post: 64 ± 20 mg/dl). These results provide new evidence on changes in blood δ-T3 concentrations with δ-T3 intake in young people and suggest the potential of δ-T3 for the prevention of atherosclerosis.
