Furthermore, all-rac-α-tocopheryl (DL-α-tocopheryl)
acetate is the industrial form of vitamin E supplementation and this
was the form of supplementation used in all references. For the three
different terminologies referring to α-tocopherol that had been used in
these references to define vitamin E administration, i.e. vitamin E (e.g.
Buckley et al., 1989), α-tocopherol (e.g. Hoving-Bolink et al., 1998) or
analysed fed α-tocopherol (e.g. Lanari et al., 1995), the amount of
supplementation could thus be expressed in IU of α-tocopherol.
