I think the amount of Vitamin D needed is provided well before you start to get sunburn.

I’m in southern Arizona, so I don’t worry about vitamin D supplements. Sunscreen is more useful...

As a physician, I often argue with dermatologists about their scaring the bejeezus out of everyone re skin cancer. Too much sunscreen is hazardous to your health. Allow 20 minutes of skin exposure and then apply sunscreen...that's all you need do.

Living in the northeast, I take no Vit D supplements during the summer, but I do take cholecalciferol during the fall, winter and spring.

Ah........ but the suncreen actually BLOCKS Vitamin D absorption, so even here in AZ we need extra D....
