When taking calcium supplements during pregnancy, calcium tablets and milk can be taken at the same time, but care needs to be taken to consume milk in appropriate and reasonable amounts. Usually doctors will advise pregnant women to start taking calcium supplements after the fourth month of pregnancy, because the fetus grows rapidly in the middle and second trimester and the need for calcium increases. And dairy products are a high quality source of calcium with high absorption rate and a large amount of protein, so calcium tablets and milk together will not produce obvious toxic side effects and will not conflict and have no effect on the human body. However, as excessive intake of calcium ions in a short period of time may lead to the accumulation of calcium ions in the body, which will increase the burden on the kidneys and will increase the probability of urinary stones. So when calcium tablets and milk are taken at the same time, you should pay attention to the total amount of calcium intake and not too much. In addition, beans and soy products, meat and eggs are rich in calcium and protein, which can be consumed in moderation during pregnancy. After calcium supplementation, to promote calcium absorption, you also need to eat more foods rich in vitamin D, such as animal offal or egg yolk, as well as more sunshine and more exercise. When taking calcium supplements, you need to be careful not to consume carbonated beverages, tea and coffee, or foods with high oxalic acid content such as spinach, sweet potato leaves and bitter gourd to avoid affecting calcium absorption.
