And, if you drink a glass of carrot juice a day, you'll receive toxic levels of vitamin A!
~40% of people don't get enough vitamin D [1]. It's not useful to categorize it as some trend, based on people just not following general recommended dosing (with more precise dosing depending entirely on personal sun exposure and skin color).
edit: As an office worker, I take 10k IU per day when I'm entirely indoors (most of the time), but vary it based on sun exposure. I based this on recent studies, and have my doctors approval with an exactly center-of-the-nominal-range vitamin D serum level.
> severe VDD was defined as serum 25(OH)D levels of <25 nmol/L, moderate deficiency as 25–50 nmol/L, insufficiency as 50–75 nmol/L, and sufficiency as >75 nmol/L.
These numbers seem high to me. The 75 nmol/L (30ng/L) is not really a reliable value. It was published in a research that raises many questions due to conflict of interests.
Hence the

> ~40% of people in the USA don't get enough vitamin D according to Dr. Holick
Where I live the norm is 20 ng/L and if we apply that, then the shocking 40% becomes more reasonable 10-15%
Seems like a reasonable measure would be to look at a native person, from ones lineage, having a relatively average pre-industrial day.
If lineage doesn't matter, and all humans are the same, you could probably just go sample some tribe members that still lives mostly outdoors, outside of developed society.
you're asking the question the wrong way around. How did Dr. Holick come up with 30ng/L and what were his incentives?
Clearly he made a lot of money publishing that research. And people who paid him also made billions. But let's focus on the rest of the world that didn't increase the norm that works by 50%
I don't want to go into this debate. The cited benefits of Vitamin D have to do with Calcium and bones. This is just absurd to me. Do people in Europe have brittle bones? Those 40% with alleged Vitamin D deficiency have issues with Calcium and get bone fractures every other day?
Vitamin D deficiency manifests itself as rickets (weakening of the bones) in children and osteomalacia (softening of the bones) in adults. Less severe vitamin D deficiency contributes to osteoporosis (bones are weaker and more likely to break). All of these are well documented outcomes in Western Europe.
More to the point, since Covid Researchers have posited that Vitamin D plays a critical role in preventing respiratory infections, reducing antibiotic use, and boosting the immune system response to infections. Vitamin D is important in regulation and suppression of the inflammatory cytokine response, which plays a role in the severe consequences of COVID-19 and ‘acute respiratory distress syndrome’ associated with ventilation and mortality in COVID-19. Vitamin D also helps the respiratory tract produce antimicrobial peptides that can lower viral replication rates.

Vitamin-D and COVID-19: do deficient risk a poorer outcome?
<a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(20)30183-2/fulltext" rel="nofollow">https://www.thelancet.com/journals/landia/article/PIIS2213-8...
Roughly 20% of the UK population (1 in 5 people) is clinically deficient (<20 ng/mL). Similar in Ireland.
If we extrapolate slightly from 'clinically deficient' to 'subnormal' then 94 % of children, 94 % of teenagers and 90 % of adults on the island of Ireland have inadequate vitamin D intakes. This is because the Sunlight UVB radiation needed to make vitamin D is only available in Ireland during the months of April through October.
For us and the other latitudes which experience a ‘vitamin D winter’ that stretches from the end of October to late March, almost everybody in Ireland needs a supplement of vitamin D and 15 µg (600 IU) is recommended on a daily basis.

This is vague and doesn't explain anything. Can you share any references that communicate what you're thinking about?

It became something of a panacea nutrient, recently around COVID.

And, regardless, I'll listen to my doctor.

There is no substance to discuss here, sorry.
