Doctor Davis has a timely post about tanning over on his Heart Scan Blog. As summer time approaches, don’t just assume being outside working on a tan will give you your dose of vitamin D. As Davis points out, there are other variables that can get in the way of your natural vitamin D production such as aging and body weight.

As I’ve mentioned on this blog in previous posts, you can’t base vitamin D levels on being out in the sun a lot. We’ve had full-time gardeners, football coaches, and outdoor enthusiasts all with low vitamin D levels! You’ve got to actually test your vitamin D with a blood test 25(OH) to know where you’re at!
