Reply To: I am confused by ng/nl
My result was 11.5 with a reference of nmol/l.
I was told it was low but not deficient.
I have been suffering for 3 years with terrible leg pain and very weak painful thighs. Could it be the cause.
I thought maybe they were not treating you at all.
So under these circumstances you may want to add another 3000-4000iu on the days you are not taking the 20,000iu dose.
The odds are that the amount they are giving you, will not get you to the 50ng/ml (125nmol/l) level.
May you feel better soon!
