  • The vitamin D that you take into your body is changed by your liver into a substance called 25(OH)D. Vitamin D (25 (OH)D) is usually measured on a scale of 30 – 100 ng/ml.  Below 30 is commonly considered deficient.
  • To determine whether you need to supplement vitamin D, you should test your vitamin D level by doing the 25-hydroxy D lab test, which measures 25(OH)D.  The Vitamin D Council recommends testing every 3-6 months when you’re trying different regimens to figure out how much vitamin D you need to maintain your optimal level.  Once you’ve reached your optimal level, GrassrootsHealth recommends, “From that point forward, testing should be done at a minimum of once a year, ideally in the early spring (late March, early April) when your vitamin D level is the lowest.  It’s a good time to adjust to make sure you don’t get too low.”
  • The optimal level of vitamin D is a matter for debate. The Vitamin D Council suggests that “a level of 50 ng/ml is the ideal level to aim for, with a range of 40 – 80 ng/ml.”  And there used to be mention that ideal is 60 – 80.
    Dr. Mercola says, “At present, based on the evaluation of healthy populations that get plenty of natural sun exposure, the optimal range for general health appears to be somewhere between 50 and 70 ng/ml.”  GrassrootsHealth Scientists like to see the serum level ‘between 40-60 ng/ml.”  Dr. Davis of Wheat Belly feels the optimal level is 60-70 ng/ml. Since people with AITD aren’t healthy and have factors that impair their production, absorption and utilization of vitamin D, the minimum 25(OH)D level for those with AITD may be need to be higher than for healthier people.
