Ingredient overview
What it is
Vitamin E refers to a family of fat-soluble compounds, with alpha-tocopherol being the main form retained by the human body. It helps limit oxidative reactions within cell membranes.
- Scientific identity: Vitamin E; family: Four tocopherols and four tocotrienols.
- How it works: Absorbed with dietary fat: Supplied esterified as tocopheryl acetate for shelf stability, it is cleaved and taken up with fat. Selected in the liver: A transfer protein preferentially retains alpha-tocopherol and returns it to circulation, which is why that form defines label activity.
- Primary function: It contributes to the protection of cells from oxidative stress and complements other antioxidant nutrients.
- What it supports: Vitamin E helps protect cell membranes from oxidative stress, supporting the normal resilience of skin and other body tissues.
- Important consideration: Its nutritional contribution depends on the amount provided and overall dietary intake.
