Tokoferoli

Tokoferoli, commonly known as Vitamin E, is a group of fat-soluble compounds that play a crucial role in human health. The most biologically active form in humans is alpha-tocopherol. Tokoferoli are potent antioxidants, meaning they help protect cells from damage caused by free radicals, unstable molecules that can contribute to aging and various diseases. This protective action is vital for maintaining cell membrane integrity and preventing lipid peroxidation.

Sources of tokoferoli in the diet include vegetable oils such as sunflower, safflower, and wheat germ oil, as well as nuts, seeds, and green leafy vegetables. Deficiency in tokoferoli is rare in developed countries but can lead to neurological problems, muscle weakness, and impaired immune function. While generally considered safe, excessive intake of very high doses of synthetic alpha-tocopherol has been linked to potential risks, though research is ongoing. Tokoferoli are also used as antioxidants in food and cosmetic products to prevent spoilage and oxidation.
