Therefore, the best time to supplement calcium is before going to bed at night or between meals, because the blood calcium concentration is the lowest in the latter part of the night and in the morning, so it is the best time to supplement calcium. Experts pointed out that in order to improve the effect of calcium supplement, it is best to eat some foods rich in vitamin C such as citrus fruits at the same time.
