VITAMIN E (Tocopherol)

A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is found in every cell of your body. It helps your nerves and muscles work well, prevents blood clots, and boosts your immune system so it can fight off infections from germs.

Vitamin E is a type of antioxidant, which means that it protects cells from damage. But if you have too little or too much vitamin E in your body, it can cause serious health problems.
