Middle-aged and elderly people should choose calcium tablets that are easy to absorb and have little irritation to the stomach. Generally, it should be taken at night, on the one hand, there are few factors affecting absorption,

On the other hand, the blood calcium of human body is the lowest at night to early morning 12. If you drink a glass of milk in the morning and a glass of milk in the morning and a cup of yogurt in the evening, you generally don't need to eat calcium tablets.

Milk is the best natural calcium, the easiest to absorb and the best choice. If you drink milk with diarrhea, you can drink yogurt or soybean milk instead. You can also eat sesame shrimp skin with high calcium content.

Eating less salt is also equal to supplementing calcium.

At the same time, we should also get more sunshine, increase vitamin D and promote the absorption of calcium.

The above is my simple summary, I hope it will help you.
