Vitamin E is a fat-soluble vitamin with the ability to improve lipid metabolism, antioxidant, regulate endocrine hormones and promote reproductive function. Vitamin E can improve lipid metabolism, and when deficient, it may increase the content of cholesterol and triacylglycerol, which may lead to atherosclerosis. Vitamin E can prevent the peroxidation of polyvalent unsaturated fatty acids in the body and inhibit the formation of lipid peroxide, thus reducing the damage to the body. It also has the role of regulating endocrine hormones and promoting reproductive function, promoting spermatogenesis and activity, promoting follicular growth and development, and promoting ovulation and luteinization, so that the corpus luteum secretion of progesterone increases.
