Calcium should be supplemented at night, because patients need calcium most at night, and it is also the easiest to absorb. Because you don't eat after falling asleep at night, you still need a certain amount of calcium in your blood. At this time, you only need to take calcium from the only part of your body-bones. On the other hand, because the human body contains less calcium when sleeping, the calcium ingested before going to bed can be absorbed quickly.

Older people over 60 need to consume 800 mg of calcium every day. Excessive calcium supplementation can not turn into bones, but will cause complications and endanger the health of the elderly.

Food calcium supplement is safer than medicine calcium supplement.

Experts suggest that the elderly should drink two cups of milk every day and eat more calcium-rich foods such as dairy products, shrimp skin, soybeans, green beans, tofu and sesame sauce. Secondly, choosing a healthy lifestyle, drinking less coffee and cola and not smoking will lead to bone loss. In addition, sunbathing and outdoor exercise are also beneficial to the absorption and utilization of calcium.
