​

Answer 1

Answer:

Sunlight doesn’t actually “provide” you with vitamin D. Rather, your body produces vitamin D when skin is exposed to the sun’s ultraviolet rays, which trigger vitamin D synthesis. The liver and kidneys convert this biologically inert form of vitamin D into biologically active forms the body can use to promote calcium absorption and bone health.
