The best time to supplement calcium is 4-5 hours before going to bed. During three meals a day, the human body can take in 300-400 mg or even more calcium from food. When the body excretes calcium from urine through calcium regulation mechanism, it can replenish blood from food at any time to maintain blood calcium level.

Part of the calcium in the blood still keeps entering the urine, so in order to maintain the normal blood calcium level, the human body has to use the calcium pool-the calcium in the bones. As a result of this self-regulation in the body, almost all the calcium in urine comes from bone calcium every morning. On the other hand, the secretion of various hormones regulating blood calcium level in the human body is different during the day and at night, so the blood calcium level is generally low at night and high during the day. Low blood calcium level at night can also stimulate.
