Which vitamin is primarily known for its antioxidant properties?

Vitamin C is primarily recognized for its potent antioxidant properties. This vitamin helps protect cells from damage caused by free radicals, which are unstable molecules that can contribute to aging and various diseases, including cancer. As an antioxidant, Vitamin C neutralizes these free radicals, thereby reducing oxidative stress in the body.

Additionally, Vitamin C plays a critical role in the synthesis of collagen, which is essential for maintaining healthy skin, blood vessels, and connective tissues. It also aids in the absorption of iron from plant-based foods and contributes to a robust immune system.

While other vitamins listed, like Vitamin A, have antioxidant properties, Vitamin C is particularly notable for its effectiveness and prominence as an antioxidant, making it the best answer for this question.
