From a food safety point of view, milk and calcium tablets can be eaten together however. From the point of view of nutritional absorption, it is not recommended to eat milk and calcium together, which may avoid the absorption of calcium. The main nutrients in milk are protein, calcium, vitamins, etc., and the main nutrient in calcium tablets is calcium, and there is usually no adverse interaction between the two, so eating them together will not affect the health of the organism. However, since both are rich in calcium, the intestinal absorption of calcium has some limitations, so eating together may increase the burden on the stomach and intestines, affecting the absorption of calcium. Therefore, it is recommended that milk and calcium tablets need to be consumed in moderation, in addition to moderate supplementation of vitamin D, vitamin D can promote the intestinal intake of calcium protein synthesis.
