As we head into the summer and sunny months up here in the Northern Hemisphere, I wanted to share a bit of thinking that fell out of some other research I was doing into Vitamin D.
Avoiding sun-induced skin cancer is not as simple as slathering on any old sunscreen you happen to grab at the drugstore.
You need to use a “Broad-Spectrum” sunscreen (good news, most are these days) but you’ll also want to keep up with your Vitamin D supplementation if you use such sunscreen religiously, or at least monitor your Vitamin D levels to maintain a serum level in excess of 50 nmol/L
