It is not by chance that vitamin E is known as the sex vitamin or the “sex vitamin”. The fat-soluble vitamin is made up of compounds called tocopherols. In Greek, tokos means offspring, and phero means to bear. The reproductive abilities of the body depend on the vitamin. It participates in the processes of ovulation and conception, but is also related to male infertility, as it changes the epithelial tissues of the testicles. Vitamin E affects the anterior lobe of the pituitary gland, which controls the activity of the sexual organs. During sexual intercourse, the sexual organs of the man and the woman need an additional amount of oxygen, which they receive from the incoming blood. The vitamin helps erythrocytes, red blood cells, to transport oxygen that enters the bloodstream through the lungs and breathing. As an antioxidant, vitamin E protects cell membranes from the accumulation of toxic products such as lactic acid. Its deficiency causes anemia. It is best to take vitamin E in its natural form, in natural foods. Otherwise, it can be dangerous, especially for people with cardiovascular diseases. Products that contain vitamin E are vegetable and animal oil, peanuts, vegetables, bananas, milk, eggs, liver, meat, as well as in the germ of cereal plants. As a food additive, it is designated as E307 (α-tocopherol), E308 (γ-tocopherol) and E309 (δ-tocopherol).
