I’m almost 70 and my vitamin D levels are excellent.
I still prefer getting older to the alternative.
When I was diagnosed with cancer at age 46, my Vit-D level was checked. It was ridiculously low. The oncologist had to order prescription-level Vit-D until the level was closer to normal. For many years before then, I’d worked late night shifts and avoided the sun. All those years, I thought I was protecting myself against cancer. Who knew?
