Unless you are deficient it's not the vitamin D. It's a whole host of other processes that benefit your body from sun exposure and the activities that go along with it. The Vitamin D is just a marker that we can detect that can also be related to that same exposure. So there's a huge number of things for which people with high levels of Vitamin D do not suffer but supplementing has no effect because the vitamin D is only correlated not causative.

Even just for vitamins, many precursor are found related to light: https://arc.aiaa.org/doi/10.2514/6.2023-4698 https://arc.aiaa.org/doi/10.2514/6.2023-4698
