Milk should not be taken together with calcium tablets, because milk itself is rich in calcium and protein, if taken together with calcium, milk will form a film, the concentration of calcium absorption in the small intestine wall will be reduced by the film, and the combination of protein and calcium in milk will precipitate, which affects the absorption of calcium. It is best to take calcium tablets at night for better results. It is best to take calcium tablets at 9-10 pm because the growth hormone secretion is the strongest during this period, which is especially beneficial to the growth and development of children. When buying calcium tablets, make sure to choose calcium tablets that are suitable for children or elderly people to take orally with adequate ingredients and easy to absorb. During the day, pay attention to more sunshine, appropriate exercise, eat fresh vegetables and fruits to replenish vitamins, and eat more high-quality protein and dietary fiber, such as fish, meat, milk, eggs, etc., to promote the absorption of calcium with balanced nutrition and high efficiency.
