The recommended daily intake of vitamin C for a 4-year-old baby is 40-50 milligrams. Vitamin C is a water-soluble vitamin that needs to be obtained through diet or supplements, but excessive intake may cause gastrointestinal discomfort. Vitamin C is crucial for the growth and development of children, participating in collagen synthesis, promoting iron absorption, and regulating immune function. It is relatively safe for 4-year-old children to obtain vitamin C from food every day, and common sources include citrus fruits, kiwifruit, strawberries, broccoli, etc. A medium-sized orange contains about 70 milligrams of vitamin C, and half a cup of chopped bell pepper contains about 60 milligrams. Moderate consumption can meet your needs. Compound vitamin supplements usually contain 30-50 milligrams of vitamin C per tablet, and it is important to avoid consuming them in combination with high vitamin C foods. The Chinese Dietary Guidelines for Residents recommend prioritizing the acquisition of nutrients from natural foods. For children who are picky eaters or have an unbalanced diet, appropriate supplements such as vitamin C effervescent tablets or chewable tablets can be selected under the guidance of a doctor. Parents should pay attention to observing whether their babies experience excessive symptoms such as diarrhea and nausea, and avoid exceeding the daily intake limit of 100 milligrams for a long time. In daily life, vitamin C in food can be preserved by providing colorful vegetables and fruits, controlling the amount of fruit juice consumed, and avoiding high temperatures and prolonged cooking. If there are symptoms of vitamin C deficiency such as repeated infections or slow wound healing, timely medical evaluation should be sought instead of increasing the dosage on one's own.
