I've seen comments to the effect of "standing outside on a sunny day in a bathing suit for five minutes is the equivalent of 10,000 IU vitamin D." No idea if that's true, and obviously UV exposure has other risks, but strictly speaking, could vitamin D ever be boosted to harmful levels by UV alone?
