Which water-soluble vitamin is known for its antioxidant properties?

  1. Thiamine

  2. Ascorbic acid

  3. Riboflavin

  4. Niacin

The correct answer is: Ascorbic acid

Ascorbic acid, commonly known as Vitamin C, is recognized for its potent antioxidant properties. Antioxidants are important because they help neutralize free radicals in the body, which are unstable molecules that can cause oxidative stress and damage cellular structures. Vitamin C plays a critical role in protecting against oxidative damage and is also involved in regenerating other antioxidants within the body, such as Vitamin E. In addition to its antioxidant capacity, Ascorbic acid is essential for the synthesis of collagen, supports immune function, enhances iron absorption, and is necessary for the maintenance of skin, blood vessels, and connective tissues. This broad range of functions underscores its importance in nutrition and health. Other water-soluble vitamins listed do not primarily function as antioxidants. For instance, Thiamine (Vitamin B1) is crucial for energy metabolism, Riboflavin (Vitamin B2) supports energy production and the metabolism of fats, drugs, and steroids, while Niacin (Vitamin B3) is involved in energy production and DNA repair. Though these vitamins are essential for various body functions, they do not exert antioxidant effects in the same way that Ascorbic acid does.
