Grapefruit: A Vitamin C Powerhouse Fruit Health Benefits of Grapefruit
Grapefruit is packed with vitamin C, providing over 50% of the recommended daily intake in just half a fruit. Vitamin C is a powerful antioxidant that protects cells from free radical damage. This helps reduce the risk of chronic diseases. Vitamin C also aids in iron absorption and collagen production for healthy skin, cartilage, ligaments and blood vessels.
