TRF, tocotrienol-rich fraction; TRP, triacylglycerol rich particles; AUC, area under the curve (arbitrary unit); α-T, α-tocopherol; γ-T, γ-tocopherol.

* Significant time × treatment × group (lipoproteins) interaction of α-T were found (3-factor repeated-measures MANOVA).

† Changes were calculated as the difference between values at each postprandial interval and baseline (0 h).

‡ Significant increment from baseline (0 h) value, P < 0.05 (Wilcoxon's signed-ranks test).

§ Significant difference of α-T content in TRP between α-tocopherol and TRF treatments, P < 0.05 (Wilcoxon's signed-ranks test)
