In daily life, calcium tablets and milk are commonly used to supplement calcium drugs and food, for milk and calcium tablets can be put together to supplement calcium, generally not recommended to put together to supplement calcium. Because if calcium tablets and milk are put together, the calcium content in the milk itself is very high, and adding calcium to it is not very meaningful, and the absorption effect of this high calcium food in the intestine is very poor. If too much calcium, iron, zinc and other inorganic salts are added to the milk, they are not well absorbed, and the excessive calcium content is a great burden on the kidneys and digestive system. In addition, the absorption of calcium and other nutritional ratios have a great relationship, for example, calcium and magnesium at a 2:1 content is easier to absorb when ingested at the same time. More sunlight can also promote the deposition of vitamin D in human bones, and vitamin D can also promote the absorption of calcium, so there are many considerations in the process of calcium supplementation.
