Patient's question:
How much International Units (IU) of vitamin A and vitamin D should a 3-year-old child consume daily? Is a ratio of 3:1 the best for vitamin A and vitamin D? If the ratio exceeds 3:1, what proportion is within the safe range? Thank you!Doctor's answer:
Health Guidance: Hello, you can get vitamins through diet. If you lack a single vitamin, you can take supplements, but you must have a doctor's prescription and follow the doctor's instructions. Otherwise, a small amount won't solve the problem, and a large amount can cause poisoning. For example, vitamin D poisoning can lead to calcium deposits in the brain, kidneys, and lungs, causing conditions like uremia.
