Vitamin E is an essential nutrient known for its powerful antioxidant properties, helping to protect cells from oxidative stress and maintain overall health. This fat-soluble compound includes eight different forms: four tocopherols and four tocotrienols, each contributing uniquely to our body’s functions.
What is Vitamin E?
Vitamin E refers to a group of eight fat-soluble compounds, which include alpha-tocopherol, the most common and biologically active form. These compounds are crucial for maintaining skin health, boosting the immune system, and protecting against cellular damage from free radicals.
History of Vitamin E Discovery
Vitamin E was discovered in 1922 by scientists Herbert Evans and Katharine Scott Bishop. They observed that rats fed a diet devoid of this nutrient experienced reproductive issues. Initially termed the “Fertility Vitamin,” subsequent studies revealed a broader spectrum of health benefits, leading to its classification as Vitamin E.
Types of Vitamin E
Vitamin E is categorized into two main classes: tocopherols and tocotrienols. Each class has four distinct forms: alpha, beta, gamma, and delta. Alpha-tocopherol is the most abundant in the human body and is often the primary focus in dietary supplements and nutritional studies.
