What does the child eat to supplement calcium? The dosage of calcium is generally 400 mg to 600 mg and 800 mg to 12 years old for children under two years old. If a child lacks vitamin D, the ability of the intestine to absorb calcium will be reduced. The preventive dose of vitamin D is 400 units per day, and it can't be overdosed, otherwise it will cause poisoning. Eat more foods with high calcium content or promote calcium absorption. For example, milk includes human milk, milk, goat milk, animal liver and egg yolk fish. Rich vitamin D can promote the absorption of calcium.

However, vitamin D in animals and plants can only be converted into endogenous vitamin D through ultraviolet irradiation, and then it can be used by the human body, so children should be properly exposed to the sun. Kelp, shrimp skin, laver and cauliflower also have high calcium content, and bones cooked with vinegar can also supplement calcium. Lactating women often eat these foods with high calcium content, which can improve the calcium content of breast milk. Pay attention to the ratio of calcium to phosphorus and supplement calcium appropriately.
