There can't be a recommended daily dose for everyone, every body is different. I quote:
"... in a correct analysis of the data used by the Institute of Medicine, it was found that 8895 IU/d was needed for 97.5% of individuals to achieve values ≥50 nmol/L."
That just means there are some people who need a very high dose. For comparison, 4000IU/d gets me well over 50nmol/L, this is also the "generally considered safe" upper limit. There was a case reported on HN where 5000IU/daily caused issues with calcium levels. You gotta get your bloodwork done.
- speakeron 6y ago50 nmol/l (20 ng/ml) is right in the middle of the 'insufficient' range. Did you mean ng/ml? The upper limit for most labs is between 175 and 200 nmol/l. In my personal example, taking about 6000 UI (plus 300 mcg K2) for a year put me just under 200 nmol/l. I did an experiment and stopped taking it for 2 months (but kept taking K2). After testing again I had dropped to 70 nmol/l (top of the insufficient range) and had mild symptoms of muscle ache and fatigue. Needless to say, I've started taking it again (and will aim for 175 nmol/l).
- gridlockd 6y agoMy levels were more than sufficient, definitely in the high range, but I don't know them off the top of my head.
