Calcium, iron and zinc cannot be supplemented at once. It is not a day or two to achieve results. According to my doctor's advice, calcium, iron and zinc should be supplemented at the same time. The combination of the three elements can effectively improve the deficiency of calcium, iron and zinc in human body and meet the needs of the body for the growth and development of calcium, iron and zinc. However, it should be noted that zinc preparations should be taken separately from other elemental preparations to avoid competing with each other to transport protein and inhibit absorption. For example, calcium preparation will affect the absorption of zinc, but zinc will not affect the absorption of calcium. Eat calcium in the morning and evening and zinc at noon, with an interval of more than 3 hours. You can eat it before and after meals, mainly paying attention to the interval between eating calcium and zinc. I hope it works for you.

I hope your sister's baby grows up healthily ~!
