How much vitamin D do you really need?
If you’ve listened to our podcasts or radio shows or read our previous newsletters then you know that we recommend higher dosages of vitamin D.
But…
even though the amount we recommend may seem high compared to the RDA…
please remember that the RDA for vitamin D is based on bad math.
Back in October of 2014, two researchers published a paper in the journal Nutrients called…
“A statistical error in the estimation of the recommended dietary allowance for vitamin D.”
In the journal they argued that the calculation of daily intake recommendations by the Institute of Medicine (IOM) were WRONG… by a lot!
Using the same data as the IOM had… the two researchers showed that based on the data… the RDA should be 8895 IU/day!
A letter was published in the same journal titled…
“Letter to Veugelers, P.J. and Ekwaru, J.P., A Statistical Error in the Estimation of the Recommended Dietary Allowance for Vitamin D.”
In the letter the authors concluded after evaluating the same data…
“Thus, we confirm the findings of these investigators with regard to the published RDA for vitamin and we call for the IOM and all public health authorities concerned with transmitting accurate nutritional information to the public to designate, as the RDA, a value of approximately 7000 IU per day from all sources.”
There you have it. These authors are suggesting an RDA of 7000 IU per day from all sources.
Let me be clear…
Optimizing Vitamin D blood levels is one of the most important things you do for your health.
There is not a system in the body that doesn’t benefit from taking vitamin D. The problem has always been that people simply do not get enough.
The bottom line is simple… Get enough vitamin D.
