Table 2 Plasma tocopherols (T) concentrations after supplementation with the α-tocopherol or tocotrienol-rich fraction (TRF) treatments (Mean values ± SEM, n = 10).

From: Alpha-tocotrienol is the most abundant tocotrienol isomer circulated in plasma and lipoproteins after postprandial tocotrienol-rich vitamin E supplementation

  1. T, tocopherols; TRF, tocotrienol-rich fraction; AUC, area under the curve (arbitrary unit); α-T, alpha-tocopherol; γ-T, γ-tocopherol.
  2. * No significant differences in plasma α-T and γ-T concentrations at baseline (0 h) were found between the treatments.
  3. † Changes were calculated as the difference between values at each postprandial interval and baseline (0 h).
  4. ‡ Significant increment from baseline (0 h) value, P < 0.05 (Wilcoxon's signed-ranks test).
  5. § Significant difference of AUC for α-T between the treatments, P < 0.05 (Wilcoxon's signed-ranks test).
