Which statement is true about Vitamin E?

Explanation:
Vitamin E’s primary role is as a lipid-soluble antioxidant. It sits in cell membranes and lipids, where it donates a hydrogen atom to neutralize reactive oxygen species and interrupts the chain reactions of lipid peroxidation. This protective action helps guard cells and tissues from oxidative damage, which is why it’s recognized as an antioxidant. It’s not a hormone that regulates blood sugar, it doesn’t regulate calcium, and it doesn’t serve as an energy source—vitamins don’t supply calories, while energy comes from carbohydrates, fats, and proteins. So the true statement is that Vitamin E acts as an antioxidant.
