I think Calci is good. My Dabao eats calcium. One pill a day is good. Calcium is an old brand for many years. Otc is safe and secure, so don't worry. In addition to calcium supplementation, vitamin D is added to promote the absorption of calcium. It's also chocolate-flavored and cartoon-shaped. Children don't resist at all, and the calcium supplement effect is also quite good! However, we should pay attention to let children exercise more at ordinary times, eat more calcium-supplemented food, bask in the sun properly, and ensure sleep at the same time, and form a good habit of going to bed early and getting up early. These daily details are also very important ~
