>What helps is going out into the sun, according to the article - and in particular, doing so regularly, and without sunblock.

This is all well and good if you live in california, but residents of alaska go out into the sun without their skin covered a lot less depending on the season.

What about vitamin d supplementation for people who cannot regularly go out and expose their skin to the sun?

>participants received high doses for five years—found no impact on cancer, heart disease, or stroke.

Again, the issue isn't "does high vitamin d cure cancer", its "does low vitamin d cause issues, and do you have enough", as I already said.

But lacking vitamin d can cause illness, and too much vitamin d can cause illness. I never claimed it cured cancer, heart disease or stroke. You're arguing someone else's argument that has nothing to do with what I've said.
