Vitamin d can't be used as calcium tablets. Vitamin d is not a calcium tablet. People with calcium deficiency often need to supplement vitamin D, which can promote the absorption of calcium and improve the utilization rate of calcium. Therefore, vitamin D is more effective when people supplement calcium. However, some people mistakenly confuse the functions of vitamin D and calcium, and simply think that vitamin D is all that is needed if calcium is deficient.

Supplementing vitamin D and calcium are two different things. It is not enough to supplement calcium just because of insufficient calcium intake. Calcium deficiency in human body still needs to increase calcium intake, including food calcium supplement, calcium supplement and so on. Vitamin D is only used as a carrier to promote the body's absorption of calcium. The absorption capacity of calcium is closely related to vitamin D. If the content of vitamin D is insufficient, no matter how much calcium is added, it will not help the human body.
