because my fitday nutritional stats show my vitamin D as so low, I did an internet search a few weeks ago on how we synthesize vitamin D ... it was very interesting, and I remember not a bit of it! (lol) But you could do the same search--my recollection is that the sun isn't as important as some other micronutrients that we need for that synthesis.

Do I sunbathe? In the Pacific Northwest in Winter? lol--that's hysterical! (remind me, what's a "sun"?)

Just my opinion, very "felt" and unscientific...I garden in good weather, I walk in good weather, and I figure that's plenty. I've never trusted sunscreen (long before the Eades said not to), from the perspective of sensible design: "had Mother Nature wanted us to use sunscreen, she would have put the sun further away." We evolved to take straight sunlight to some degree, eh?
