Thank you so much for this article. I really cannot stress how important it is for many of us who lead stressful lives to supplement our nutrition with vitamins. Personally, take a daily multivitamin completely changed my life…

The thing about Vitamin D is that you can get it just by being outside. It is absorbed through the skin The NATURAL way. But the so called health experts say you have to use sun screen and there for it BLOCKS your body from getting the Vitamin D that it needs.

Vitamin D is made in the skin when in sunlight.
Too much can be toxic.
The experts cannot decide on the daily dosage so it is hard to know what is needed.
As always check with doctor if you think you need extra vit D.

I believe vitamin D is very important, as most people in this world either do not get out enough, or do not see the sun due to where they live. It is one of the most lacking nutrients in the world and should always be supplemented. It can help many health issues such as infertility etc.

I live in beautiful SUNNY San Diego and for some reason I have been told I am extremely deficient in Vitamin D… therefore they gave me a high “dose” (if that is what you call it) of vitamin D pills. It is annoying cause I take so many vitamins anyways, but thank goodness for coupons [URL removed by moderator] or I would be broke with all the vitamins I have to purchase. I would say I would go out in the sun more but I am worried about wrinkles! Oh well, looks like it is Vitamin D in capsule form for me!

“the committee emphasizes that, with few exceptions, all North Americans are receiving enough calcium and vitamin D.”

This is especially interesting because it is contrary to what many studies in Europe and Northern Europe found out. For example, danish authorities have now asked to add Vitamin D to milk and dairy products . Studies rather consistently underline that Vitamin D production in northern hemispheres (north 50 degrees) is too low during winter.

As someone who has low blood calcium post thyroid surgery, and in addition low vitamin D levels, I take supplements of each kind daily. But it’s the supplementation of vitamin D that concerns me, as well as my physician. He has mentioned a word I rarely see when reading about taking vitamin D. That word is: ‘Toxic.’

From the perspective of a patient it’s nice to see a report like this one from the IOM. It at least counterbalances some of the other items out there about vitamin D – many of which amounting to nothing more that overblown sales-pitches.

Thank you for this blog entry.

“the committee emphasizes that, with few exceptions, all North Americans are receiving enough calcium and vitamin D.”

Without testing, it would be very difficult to know whether indeed North Americans are receiving enough Vitamin D.

It is peculiar that the IoM did not differentiate recommendations by weight or risk factors other than advanced age.

Does this mean that, as the Vitamin D Council asks “…a three-pound premature infant take virtually the same amount as a 300 pound pregnant woman”? Professor Bruce Hollis @MUSC has shown that pregnant and lactating women require 5,000 IU/day.
