There is no such thing as “should you take more calcium in the spring”, it depends on your body’s needs. Season has no significant effect on calcium absorption. It is the time of the day that determines the rate of calcium absorption. Our skin produces vitamin D when exposed to ultraviolet rays, which is a key factor in promoting calcium absorption, so it is important to get more sunlight. Calcium absorption increases in the summer when UV activity is intensified. Seasons also do not lead to different calcium requirements. Instead different ages have different calcium requirements. Generally the requirement increases gradually with age. Pregnant women, women in labor, and the elderly have particularly high calcium needs. Finally, the use of calcium supplements need to go to the hospital to improve the relevant examination, under the guidance of the doctor to use.
