Extended information:

Calcium tablets are best taken before going to bed. Blood calcium levels are lower at night and higher during the day. Because a reasonable and balanced diet can generally meet the daily calcium needs. But at night, urinary calcium will still be excreted, and there is no calcium supplement in food, so part of the calcium in the blood will be released to make up for the loss of urinary calcium.

Relatively speaking, calcium absorption will be enhanced at this time, and the calcium supplement effect will be better. In addition, nocturnal hypocalcemia will stimulate the secretion of parathyroid hormone and accelerate the decomposition of bone calcium. If you properly supplement calcium preparations before going to bed, you can provide sufficient "ammunition" for the night and reduce the lack of bone calcium in the body. Calcium also has a calming effect, helping you sleep. However, going to bed after taking calcium tablets can easily increase the risk of urinary tract stones. It is best to take them 2 to 3 hours before going to bed.
