English-Hanzi/Vitamin D directs the mineralization of bones

Vitamin D directs the mineralization of bones. Basically, it tells calcium what to do and where to go in the body. Without enough vitamin D, no matter how much you take, you cannot absorb enough calcium. Adequate sunlight can ensure adequate vitamin D, which is necessary for calcium absorption. As we age, our skin's ability to make vitamin D through sunlight decreases, so it is necessary to get more sunlight. The main source of vitamin D is produced by the skin through sunlight, but some foods also contain small amounts of vitamin D.
