Vitamin D - are you getting enough? How do you know? Simple: get a blood test.
Vitamin D production by our bodies need sunlight, ultraviolet specifically, to be made from cholesterol. The best hours to get that sunlight is 11am to 2pm, without sunscreen. Sunscreen will block Vit. D production by 90% or more. If you'll be in the sun for hours due to work or play, wear long sleeves and a wide brimmed hat for protection. To get Vit. D production, though, your skin needs to be exposed to direct sunlight 30-40 minutes daily.
If you're thinking you got it covered by taking Vit. D, you could be fooling yourself without testing. I thought with my minimal exposure and supplement I'd be good. Nope! Recent tests showed my level to be 20! Range is 30-100ng/mL with optimum above 50.
I've got some work to do - and so might you.
