When supplementing children with vitamin C, it is still recommended to supplement them with food instead of pills. Vitamin C is a water-soluble vitamin, which is very high in green vegetables and fruits. For example, tomatoes, mustard greens, spinach, grapes, kiwis, apples, jujubes, etc., which we usually see, are rich in vitamin C. Try to prepare enough fruits and vegetables for your children in your usual diet. If you find that your child is picky about food and partial eclipse, you must be able to help your child correct it at the first time. Children must be urged to eat enough vegetables and fruits, so as to ensure that the body will not have the problem of vitamin C deficiency.
