Does it make your skin more clear or what?

All living things require energy from the sun. You'll feel extremely run-down if you're low on Vitamin D.
You can get it by spending time outside, or eating foods that have come from living things that have spent time in the sun (you won't get it from processed foods though) like fruit, veg & meat.

Most people low on Vitamin D will feel extremely tired and have no energy to do things. It can also mild depression.
Most importantly, low Vitamin D makes your bones soft.

Depression
Anal tightening etc

But then he'll get depressed once he gets to DWUW & realizes it never got a video.

For intestinal Ca2+ absorption!!

It's good for D because it's vitamin D i guess

You don't absorb calcium without it. So it's vital for healthy strong bones

Vitamin D also helps in the production of the growth factor, I think that there less than five natural sources of D, salmon, the yolk, some mushrooms, the best source possible is sunglight exposure for at least 15 minutes. Vitamin D defficiency is most commonly related to osteomalacia (bones softening) and depression, due to lack of stimulation of some neurons.

It's not a daily fatal need, but you need it to maintain your bones.

On point!

This explains.

I feel so out of energy the last few weeks as I spend last time in sunlight.
