Major circulating D: 25-hydroxy-vitamin D is the major circulating form of Vit. D and the best test to check Vitamin D status. One can check the 1,25-hydroxy form- that's the active form but is not a reliable way to see if you have adequate levels of D. We get D primarily by being in the sun so most Americans become deficient in fall and winter. I advise 5000 iu of D3/day in fall/winter. See http://tinyurl.com/2chkcer
