Best Time to Take Calcium Supplements
The best time to take calcium supplements is just before you go to bed each day. During three meals a day, the body can take in 300-400 milligrams, or more, of calcium from food. While the body excretes calcium from the urine through a calcium-regulating mechanism, the blood can always be replenished with calcium from food to maintain blood calcium levels.
At night, the body no longer eats, and urine will be formed as usual, and part of the calcium in the blood is still constantly going into the urine, so in order to maintain a normal blood calcium level, the body will have to use the calcium reservoir - bone calcium. The result of this self-regulation in the body is that almost most of the calcium in the urine every morning comes from bone calcium.
On the other hand, blood calcium levels are generally lower at night and higher during the day, and low blood calcium levels at night can also stimulate parathyroid hormone secretion, which speeds up the breakdown of bone calcium. Before going to bed to supplement calcium, can provide a calcium source for this calcium regulation at night, blocking the body to move bone calcium, at the same time calcium also helps sleep, therefore, before going to bed is the best time of day to supplement calcium.
