Claims for vitamin E in angina pectoris have not been based on controlled observations. Even some negative 'eports have not been adequately controlled as to nonspecific factors. Hence, this study of the effects of alpha tocopherol on cardiac pain used a method of investigation carefully Controlled as to psychologic factors which might affect the patient's response oi the examiner's interpretati...

A study was carried out to assess the bioavailabilities of several forms of vitamin E in lambs. A total of 40 lambs was allotted to eight dietary groups of five each and supplemented or not daily for 60 d with equimolar amounts of different vitamin E compounds as follows: 1) control, no supplemental vitamin E, 2) DL-alpha-tocopheryl acetate, 3) D-alpha-tocopheryl acetate, 4), D-alpha-tocopheryl...

BACKGROUND An adverse hematological interaction between vitamins E and K has been reported, primarily in patients on anticoagulants. However, little is known regarding circulating levels or tissue concentrations of vitamin K in response to vitamin E supplementation. The purpose of this study was to examine the effect of different levels of dietary alpha-tocopherol on phylloquinone and menaquino...

The instability of vitamin A alcohol relative to vitamin A acetate has been studied in vivo and in vitro. Vitamin A alcohol is more unstable than vitamin A acetate in human gastric and duodenal juice and in rats' stomachs and intestines and is more marked at lower pH levels and in rats' stomachs. Alpha tocopherol improved the absorption curve of vitamin A alcohol in man by protecting it in gast...

Several lines of evidence suggest that oxidatively modified low density lipoprotein (LDL) is atherogenic and that antioxidants may protect LDL against oxidation. In addition, cigarette smoking is known to induce oxidant stress. We have examined the effect of ingestion of the antioxidants D,L-alpha-tocopherol (vitamin E) and beta-carotene and of smoking on the resistance of LDL against copper-me...

serum alpha-tocopherol of98(62 male and 36 female) cancer patients and 30 (13 male and 17 female) control healthy subjects was investigated. the cancer patients showed a significantly low level of alpha-tocopherol as compared to control healthy subjects. also, significantly higher levels of serum alpha-tocopherol were found in complete remission patients as compared to the partial response pati...

Relative vitamin E status of pigs fed natural or synthetic vitamin E was evaluated based on serum and tissue alpha-tocopherol concentrations. Individually fed finishing gilts at a BW of 70.5 kg (n = 24) were allotted to dietary treatments based on initial BW. The 5 dietary treatments consisted of a positive control diet using synthetic vitamin E acetate (Syn E Ac) supplemented at 22 mg/kg, and ...
