The old saying that lots of sunshine and fresh air makes us healthy probably has to do with absorbing vitamin D.

It's the quantity of sunshine that's a problem. Most days/weeks, we don't get enough. Then we go waaaay overboard when we go on vacation and bake for hours on the beach, leading to pre-cancerous genetic damage to our skin.

10-15 minutes per day is enough to synthesize colecalciferol from its precursor molecule, 7-dehydrocholesterol. Alternatively, one can take oral colecalciferol supplementation.

It is interesting to note that neither D3 or D2 are biologically active in their own right; they are both metabolized in the liver and kidneys to the active form.

Oh good during the summer I can justify me only spending 15 minutes at the pool at a time and not getting tan. I'm vitamin D bathing
