Posted: Thu Sep 04, 2008 2:57 pm Post subject: Vitamin D Levels
a question for jimmylegs -
I have the report back on my vitamin D, 25-OH Levels. Results were 39 ng/ml - report says that anything over 30 ng/ml are optimal. What is the difference in the unit of measure used in my report to the unit of measure you used in a previous post?

vitamin d3 - get it up over 100 nmol/L.
you can do this in the long term by taking 4000IU per day. balance carefully with calcium (1200mg), magnesium(1200mg), and zinc(normally up to 50mg).
heya sharon, the short answer is, multiply your ng/mL result by 2.496 to get nmol/L.
for anyone coming upon the subject cold, the useful link below accesses a number of useful conversion factors including vitamin d3 (two metabolites; we're interested in 25(OH) or 25hydroxy, of course) near the bottom:
sharon's lab's optimal 30+ ng/mL converts to only 75 nmol/L. that sounds like optimal from an musculoskeletal osteoporosis standpoint only, not an immune perspective.
that said, multiplying sharon's 39 ng/mL by 2.496 is 97 nmol/L. so, pretty close to 100 nmol/L! 100-250 is more in line with the immune system's "normal range". 150 nmol/L is a pretty good and safe starting sweet spot for optimizing the immune system's functionality.
150nmol/L / 2.496 = 60 ng/mL - so sharon it looks to me as though you are in good shape to keep on supplementing your socks off
**not forgetting** the importance of daily calcium, magnesium, and zinc. if you don't already do so, make sure your magnesium is split up through the day - some taken with d3, some taken on its own to facilitate other necessary biochemical interactions.
hey there, you're very welcome! don't forget to take some mag on its own, away from the d3
also, a quick caution on the zinc:
it's wise to get it tested before adding more to your current daily regimen. whatever you're currently getting may be sufficient.
once you have a result, see where you are compared to zinc status of female healthy controls (for table of healthy zinc ranges for females see thread: zinc, ms, boys, girls, controls). then you can go for that bit higher, if needed.
i was very deficient, was told to take 100mg per day for one month. i was more sporadic, taking none some days, 50mg some days, and 100mg other days, over three months, and that resulted in zinc excess. as you will note in the zinc ms boys girls thread if you are interested
