Cancer-preventive activities of tocopherols and tocotrienols.
Ju J, Picinich SC, Yang Z, Zhao Y, Suh N, Kong AN, Yang CS. Ju J, et al. Carcinogenesis. 2010 Apr;31(4):533-42. doi: 10.1093/carcin/bgp205. Epub 2009 Sep 11. Carcinogenesis. 2010. PMID: 19748925 Free PMC article. Review.
One possible explanation for the lack of demonstrable cancer-preventive effects is that high doses of alpha-tocopherol decrease the blood and tissue levels of delta-tocopherols. ...Based on this information, we propose that a gamma-tocopherol-rich mixture of …

alpha-Tocopherol in chloroplasts: Nothing more than an antioxidant?
Mesa T, Munné-Bosch S. Mesa T, et al. Curr Opin Plant Biol. 2023 Aug;74:102400. doi: 10.1016/j.pbi.2023.102400. Epub 2023 Jun 11. Curr Opin Plant Biol. 2023. PMID: 37311290 Free article. Review.
Among the eight forms of vitamin E, only tocopherols are essential compounds that are distributed throughout the entire plant kingdom, with alpha-tocopherol being the most predominant form in photosynthetic tissues. ...This is of utmost relevance since tocopherol …

Vitamin E and Multiple Health Outcomes: An Umbrella Review of Meta-Analyses.
Xiong Z, Liu L, Jian Z, Ma Y, Li H, Jin X, Liao B, Wang K. Xiong Z, et al. Nutrients. 2023 Jul 25;15(15):3301. doi: 10.3390/nu15153301. Nutrients. 2023. PMID: 37571239 Free PMC article. Review.
The relationship between vitamin E intake or circulating alpha-tocopherol and various health outcomes is still debatable and uncertain. We conducted an umbrella review to identify the relationships between vitamin E intake or circulating tocopherol and health outcom …

Vitamin E bioavailability in humans.
Lodge JK. Lodge JK. J Plant Physiol. 2005 Jul;162(7):790-6. doi: 10.1016/j.jplph.2005.04.012. J Plant Physiol. 2005. PMID: 16008106 Review.
We used a non-competitive uptake approach to compare the plasma biokinetics of deuterated natural (RRR) and synthetic (all rac) alpha-tocopheryl acetate in smokers and non-smokers. The study was comprised of two 4-week treatments with 400 mg/d (either RRR-alpha-tocopher …
