Calcium tablets, why are they taken at night, and it is better to take them before going to bed?

Calcium supplementation may be something that many people are doing. Drinking milk to supplement calcium is something that even kindergarten children already know. It's just that some people choose other ways to supplement calcium, and calcium tablets are one of them.

Calcium tablets, as the name suggests, are calcium supplements for the body. Compared with dietary calcium supplements, calcium tablets are more simple and convenient, and you can take them with you when you go out. As for the timing of taking calcium tablets, some people may take it as if they were taking medicine.

In fact, taking calcium tablets also has time, the biggest reason is to improve the absorption rate of calcium tablets in the human body. Taking calcium tablets at different time periods also has a large difference in the absorption rate. Doctors and nutritionists recommend taking calcium tablets at night.

The best time for the human body to supplement calcium is before going to bed at night. You may have done a blood calcium test before, but blood calcium cannot be used as a diagnostic indicator for calcium deficiency. Calcium in the blood is in a balanced state, and the calcium ingested from food during the day is also excreted in the urine. After sleep at night, the body no longer eats. If you wake up in the middle of the night to go to the toilet, the calcium excreted in the urine is actually the calcium released from the bones.

When you wake up in the morning to urinate for the first time, the calcium in the urine is also the calcium freed from the bones into the blood. Calcium deficiency can also occur if too much calcium is mobilized in the bones. Therefore, when supplementing calcium, it is necessary to add calcium to the body in time before going to bed at night.

Blood calcium levels are generally high during the day and low at night. This condition also stimulates the secretion of parathyroid hormone, which further accelerates the breakdown of bound calcium in the bones. Taking a calcium tablet at night before going to bed will increase the level of calcium in the blood. The calcium level in the blood is increased, and the calcium in the bones will not be used temporarily.
