Grapefruit is an excellent source of vitamin C. It supports the immune system and reduces cold symptoms or severity of these symptoms. Many scientific studies suggest that vitamin C is a cold-fighter. Vitamin C also prevents free radical from causing damage and triggering inflammatory conditions, such as asthma, osteoarthritis, and rheumatoid arthritis.
