The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
70% of the US population has inadequate vitamin D levels. So this is everyone. And so I think that insufficient levels defined as less than 30 nanograms per milliliter, and that's defined by the Endocrine Society, looking at a lot of different aggregate studies, all-cause mortality, for example.

probably 80% are insufficient or low in vitamin D
And we see over 67% are deficient. And this is important to understand, Andrew. 67% are deficient at the minimum level to prevent a deficiency disease, not the optimal level that you or I might think is good like vitamin D over 45 or ferritin iron store over 45.
70% of the US population has inadequate vitamin D levels. 70 of the wholeing US. So, this is everyone. And so, I think that insufficient levels defined as less than 30 nanogs per milliliter.
vitamin D insufficiency was defined as a saram 25 hydroxy vitamin D as less than 30 nanograms per ml
Very relevant as ~30% of US population is vitamin D deficient (serum <20ng/ml).
more than 70% of the U.S. population has vitamin D levels below 30 ng/ml, which is considered the threshold for sufficiency.
NHANES data reveals that about 70% of the U.S. population has vitamin D levels below 30ng/ml, barely touching the baseline of sufficiency.
Around 70% of the US population has inadequate vitamin D levels.
more than 70% of older U.S. adults are insufficient
Approximately 96% of Americans not taking vitamin and mineral supplements have insufficient vitamin D levels, whereas only 25% using supplements containing vitamin D have insufficient levels. https://t.co/LhTEbOdQuF
~70% of the US population has vitamin D levels below 30 ng/ml.
70% of the U.S. population, you know, is not getting enough.
70% of the US population does not have adequate levels of vitamin D
vitamin D which 70% of the population is deficient in
as I mentioned earlier around 70% of the US population does not get adequate levels of vitamin D
Vitamin D inadequacy is pretty prevalent in the United States. Around 70% of the population doesn't have what's considered to be adequate levels.
according to Ann Haynes data approximately 70% of the u.s. has what is called vitamin D insufficiency while a further 28.9% has low enough levels to be called deficient
This may explain why approximately 70% of the U.S. has what is called vitamin D insufficiency while they further 28% has a low enough level to be called deficient.
About 70 percent of the U.S. population has inadequate vitamin D.
as I mentioned about it's widespread prevalency in terms of inadequacy so about 70% of the population has inadequate levels of vitamin D which we'll talk about in a minute it's about 30 nanograms per milliliter or less
So I think here in concluding thoughts overall not only this the findings of this study but the other the other studies that I talked about really do give strong support to this idea that everyone should probably be supplementing with at least some vitamin D to make sure they're avoiding deficiency. And I mentioned as I mentioned earlier deficiency is a widespread you know problem in the United States up to 70% of people are either deficient or insufficient.
Up to 25% of the population has one of these alals and it can double the risk of Alzheimer's disease if you have one of them. If you have two of these alals, you can have up to a t-fold higher risk of Alzheimer's disease. Vitamin D is not just a vitamin. Vitamin D gets converted into a steroid hormone that regulates over a thousand genes in our body. It enters the nucleus of our cells and it regulates, it activates and turns on or it suppresses and turns off up to nearly 5% of the protein encoding human genome. This is very relevant because up to 70% of Americans fall into a range known as deficient or insufficient. So almost 30% of Americans actually are vitamin D deficient. They have levels of 25 hydroxy vitamin D below 20 nanogs per milliliter. The other 40% or so has levels that's known as insufficient. So these are people that have vitamin D levels above 20 nanogs per milliliter, but they're below 30 nanogs per milliliter.
about 30% of the population has levels of 20 nanogs per milliliter or below. That's deficient.
And then the other 40% has levels which is considered insufficient. So that would be 30 nanogs per milliliter or below.
