Mahan DC, Kim YY, Stuart RL: Effect of vitamin E sources (RRR- or all-rac-α-tocopheryl acetate) and levels on sow reproductive performance, serum, tissue, and milk α-tocopherol contents over a five-parity period, and the effects on the progeny. J Anim Sci 2000, 78: 110–119....
Bioavailability of α-tocopherol stereoisomers in lambs depends on dietary doses of all-rac- or RRR-α-tocopheryl acetate - ScienceDirect When supplementing lamb diets with vitamin E, an equivalence factor of 1.36 is used to discriminate between RRR- α -tocopheryl acetate and all-rac - α -...
Before and after each supplementation period subjects underwent a biokinetic protocol (48h) with 150mg deuterated RRR- or all rac-α-tocopheryl acetate. During the biokinetic protocols, the elimination of endogenous plasma α-tocopherol was significantly faster in smokers ( P<0.05). However, ...

Long-term oral vitamin E supplementation in cystic fibrosis patients: RRR-alpha-tocopherol compared with all-rac-alpha-tocopheryl acetate preparations Thiele, Oral supplementation with all-Rac- and RRR-alpha-tocopherol increases vitamin E levels in human sebum after a latency period of 14-21 days, ...
Comparison of all-rac-alpha-TOH (dl-alpha-TOH) with RRR-alpha-TOH (d-alpha-TOH) in the resorption-gestation test revealed an activity ratio of 1:1.38. Compared with 2-ambo-alpha-TOH, RRR-alpha-TOH was more active by a factor of 1.34 (resorption-gestation) or 1.45 (myopathy). On ...

To test this, 24 volunteers were subjected to a randomized daily supplementation with either 400 mg RRR-α-tocopheryl acetate (RRR-α-toc) or 400 mg all-rac-α-tocopheryl acetate (all-rac-α-toc) for 14 days. Fasting blood samples, facial sebum samples, and lower-arm skin-surface lipids...
