Research Papers that Mention the Interaction

Supplementation with alpha-tocopherol also resulted in a significant (P=0.04) decrease in plasma gamma-tocopherol levels among males.
Melanoma research  •  2004  |  View Paper
Compared with placebo, supplementation with alpha-tocopherol reduced serum gamma-tocopherol concentrations by a median change of 58% [95% CI = (51%, 66%), P < 0.0001], and reduced the number of individuals with detectable delta-tocopherol concentrations (P < 0.0001).

1 nmol/mL. Although eight times more gamma-tocopherol was infused, plasma alpha-tocopherol levels also increased from 26 +/- 7 to 39 +/- 9 nmol/mL at 8 hours and decreased to 24 +/- 5 nmol/mL at 24 hours.

Secondly, the use of alpha-tocopherol supplements significantly reduces serum gamma-tocopherol , and this may have important biological effects.

AT supplementation significantly decreased GT levels.
Because AT supplementation decreases circulating gamma-tocopherol (GT), we evaluated supplementation with GT (800 mg/day), AT (800 mg/day), the combination or placebo for 6 weeks alone AT and GT concentrations, biomarkers of oxidative stress, and inflammation in subjects with MetS (n=20/group).
Plasma AT and GT levels increased following supplementation with AT alone or GT alone or in combination.

CONCLUSION Naringenin, carotenoids and probably gamma-tocopherol can impair alpha-tocopherol absorption whereas vitamin C and phenolic acids have no effect.
European journal of clinical nutrition  •  2007  |  View Paper
Supplementation with alpha-tocopherol caused alpha-tocopherol levels to rise (13.2 +/- 3.7 to 27.3 +/- 14 mug/mL), but gamma-tocopherol levels to decrease (4.1 +/- 1.6 to 3.5 +/- 1.1 mug/mL).

Serum and cellular gamma-tocopherol increased 4-fold (P < 0.001) in the mixed tocopherol group, whereas red blood cell gamma-tocopherol decreased significantly after alpha-tocopherol supplementation.

RESULTS The possible factors implicated for failure of vitamin … suboptimal dosages of vitamin E, (4) the suppression of gamma-tocopherol … alpha-tocopherol , (5) the use of vitamin E supplementation without the concurrent use of vitamin C, (…) the poor patient compliance and the lack of monitoring of vitamin E levels.
