The Big Vitamin D Mistake
Could someone help me understand this?<p>&gt;it was found that 8895 IU&#x2F;d was needed for 97.5% of individuals to achieve values ≥50 nmol&#x2F;L. Another study confirmed that 6201 IU&#x2F;d was needed to achieve 75 nmol&#x2F;L and 9122 IU&#x2F;d was needed to reach 100 nmol&#x2F;L. The largest meta-analysis ever conducted of studies published between 1966 and 2013 showed that 25-hydroxyvitamin D levels &lt;75 nmol&#x2F;L may be too low for safety and associated with higher all-cause mortality, demolishing the previously presumed U-shape curve of mortality associated with vitamin D levels.<p>What is IU&#x2F;d? What is nmol&#x2F;L? Could someone ELI5 the entire abstract for me? Well, maybe a little more than 5, I get that there was an error estimating recommended levels and we&#x27;re not getting enough.
