So many people take vitamin D these days (including myself) that I think people have just accepted that we'll never get "enough sun" again.
Maybe it's for the best since it gets damaged by it.

I just take multivitamins and don't even think about my vitamin intake beyond that.

I believe current literature thinks Vitamin D supplementation doesn't help at all unless you have a severe deficiency.
As in you don't see all the positive health outcomes correlated with high serum Vitamin D if you supplement. You just effectively prevent things like Rickets.

If I remember correctly it's because the human body just ends up pissing most of it away.

I had one enough for a doctor to say I needed to take it, so I guess that counts. It was years ago and I recently switched to these drops because I heard Vitamin D and K2 help the other get absorbed.
It's indeed hard to say if supplements work unless you were deficient. It's not like you wake up and appreciate having 3% higher usable Vitamin ___ for your ___ organ.
I've seen some people insist that multivitamins don't even do anything when you compare it to getting it from actual food.
