Vitamin E Supplementation

Vitamins play important roles in female health. They are essential for many functions, including menstruation and ovulation, oocyte (egg) quality and maturation. Vitamin E was first discovered in 1922 as a substance necessary for reproduction. It has become widely known as a powerful lipid-soluble antioxidant. There are various reports on the benefits of vitamin E on health in general. Vitamin E helps your body create and maintain red blood cells, healthy skin, eyes and strengthens your natural immune system. However, despite it being initially discovered as a vitamin necessary for reproduction, to date studies relating to its effects in this area are lacking. Vitamin E supplementation may help reduce the risk of pregnancy complications involving oxidative stress, such as pre-eclampsia. This chapter is written to provide a review of the known roles of vitamin E in pregnancy.

Sen, Chandan K., Mustafa Atalay, Jyrki Ågren, David E. Laaksonen, Sashwati Roy, and Osmo Hänninen. Fish oil and vitamin E supplementation in oxidative stress at rest and after physical exercise. J. Appl. Physiol.83(1): 189–195, 1997.—Fish oil supplementation and physical exercise may induce oxidative stress. We tested the effects of 8 wk of α-tocopherol (vitamin E) and fish oil (FO) supplementation on resting and exercise-induced oxidative stress. Rats ( n = 80) were divided into groups supplemented with FO, FO and vitamin E (FOVE), soy oil (SO), and SO and vitamin E (SOVE), and for FOVE and SOVE they were divided into corresponding exercise groups (FOVE-Ex and SOVE-Ex). Lipid peroxidation [thiobarbituric acid-reacting substances (TBARS)] was 33% higher in FO compared with SO in the liver, but oxidative protein damage (carbonyl levels) remained similar in both liver and red gastrocnemius muscle (RG). Vitamin E supplementation, compared with FO and SO, markedly decreased liver and RG TBARS, but liver TBARS remained 32% higher in FOVE vs. SOVE. Vitamin E also markedly decreased liver and RG protein carbonyl levels, although levels in FOVE and SOVE were similar. Exercise increased liver and RG TBARS and RG protein carbonyl levels markedly, with similar levels in FOVE-Ex and SOVE-Ex. FO increased lipid peroxidation but not protein oxidation in a tissue-specific manner. Vitamin E markedly decreased lipid peroxidation and protein oxidation in both FOVE and SOVE, although liver lipid peroxidation remained higher in FOVE. Despite higher levels of hepatic lipid peroxidation at rest in FOVE compared with SOVE, liver appeared to be relatively less susceptible to exercise-induced oxidative stress in FOVE.

Vitamin E Supplementation

Determination of reliable bioindicators of diabetes-induced oxidative stress and the role of dietary vitamin E supplementation were investigated. Blood (plasma) chemistries, lipid peroxidation (LPO), and antioxidant enzyme activities were measured over 12 weeks in New Zealand White rabbits (control, diabetic, and diabetic + vitamin E). Cholesterol and triglyceride levels did not correlate with diabetic state. PlasmaLPOwas influenced by diabetes and positively correlated with glucose concentration only, not cholesterol or triglycerides. Liver glutathione peroxidase (GPX) activity negatively correlated with glucose and triglyceride levels. Plasma and erythrocyte GPX activities positively correlated with glucose, cholesterol, and triglyceride concentrations. Liver superoxide dismutase activity positively correlated with glucose and cholesterol concentration. Vitamin E reduced plasma LPO, but did not affect the diabetic state. Thus, plasmaLPOwas the most reliable indicator of diabetes-induced oxidative stress. Antioxidant enzyme activities and types of reactive oxygen species generated were tissue dependent. Diabetes-induced oxidative stress is diminished by vitamin E supplementation.
