However, as of 2015, studies show that people who regularly take vitamin C supplements or eat diets rich in vitamin C experience shorter colds with milder symptoms.
Eating a balanced diet is the ideal way to get enough vitamin C, notes MedlinePlus. Some food sources of vitamin C include citrus fruit, kiwi fruit, strawberries, raspberries and watermelon.
