Pediatrics, 1986
To the Editor.— I read with great interest the commentary by J. A. Lemons and M. J. Maisels on vitamin E.1 The timing for such a critical review of the subject could not be more appropriate because vitamin E is now being prescribed widely and in large doses to very low birth weight infants.

BioFactors, 1999
Natural (RRR) or synthetic (all-rac) forms of alpha-tocopherol are available (usually as acetate esters) for use as vitamin E supplements. In animal tests, the natural stereoisomer, RRR-alpha-tocopheryl acetate, is 1.36 times more biologically potent than all-rac-alpha-tocopheryl acetate, an equimolar mixture of eight stereoisomers [8,15,40-43].

Archives of Dermatology, 1982
To the Editor.— The cautionary commentary by Roberts 1 on vitamin E toxicity stimulates me to record my observations. I conduct an Aging Skin Clinic at the Hospital of the University of Pennsylvania, Philadelphia. A rare opportunity is presented to find out what middle-class, middle-aged white women think is dietetically healthful.

Vitamin E compounds are biologically essential fat-soluble antioxidants derived from 6-chromanol. This chapter covers the representative literature on the preparation of various stereoisomeric forms and homologues of tocopherols and tocotrienols, and of respective starting materials and intermediates.
