Do Americans no longer need vitamin D?

Can 78 million Americans get healthier by way of changing the definition of healthy vitamin D levels? A new study says yes.

Back in 2010 there was much buzz in the scientific research community about the impending change in recommendation for adequate levels of vitamin D. Researchers who studied vitamin D and were amassing the tsunami of research that was accumulating since 2008 were advocating 2,000 IU/day.

The more politically tuned-in were suggesting that the conservative Institutes of Medicine might hedge their bets and go with only 1,000 IU/day.

When the IOM came out with their pronouncement, inveterate Pollyannas could manage only a tepid golf clap at the doubling of levels—albeit to only 800 IU/day.

Now, a new study published this week by researchers at Loyola University have calculated that 78.7 million adults once considered to have insufficient vitamin D levels now have sufficient levels under the new guidelines, which deem sufficient blood levels of 25-hydroxycholecalciferol (aka, vitamin D) to be 20 ng/ml.

No vitamin D researcher agrees with this level. They will all tell you the bare minimum should be set at 30 ng/ml, which is fully 50 percent higher. And progressive physicians encourage patients to get levels at 50 ng/ml or higher.

Where do you think vitamin D levels should be set? Comment below.
