In spring, children can take calcium supplements in moderation, but calcium supplementation for children is not purely limited to a certain season. As the temperature rises in spring, the sunshine is sufficient, coupled with the increase of children’s outdoor activities, the vitamin D converted by the skin through sunlight also increases accordingly, but if the calcium content in food is insufficient and other reasons, it may lead to the child’s symptoms of calcium deficiency. Therefore, the appropriate amount of calcium supplementation can ensure the growth and development of children on the demand for calcium, such as calcium carbonate, milk calcium, calcium acetate, etc., but need to be used under the guidance of a doctor to avoid excessive supplementation, so as not to cause hypercalcemia and other adverse reactions. In daily life, you can eat more calcium-rich foods, such as milk, tofu, etc., avoid picky eating and partiality, so as not to lead to nutritional imbalance, and promote the growth of children’s bones.
