Recently, as part of my yearly physical, I requested to have my Vitamin D levels checked. I assumed my levels would be pretty good between my supplement intake, teaching an outdoor Boot Camp Class a few times a week and walking the dog:-) My levels were OK but not optimal.
Answering a questionnaire on skin color, BMI, age, where you live and how much sun exposure you get on a daily basis gives us a good estimate on the recommended supplementation needs according to your responses but testing your blood is imperative. I recommend this take at home test fromthe Vitamin D Council.It seems pretty economical and expedient. Please visit my Vitamin D Website to get started with the Vita D quiz.
