Vitamin C is found naturally in fruits (especially citrus fruits) and leafy vegetables. Good sources include acerola cherries, rose hips, citrus fruits or juice, guavas, peppers, blackcurrants, parsley, mustard greens, green leafy vegetables, cantaloupe, papaya, strawberries, and tomatoes. Vitamin C is the most unstable of all vitamins and is quickly destroyed by heat, light and exposure to air.
