I saw this in the October issue of the Canadian Reader's Digest, and found it quite interesting.

Anybody know anything much about Vitamin D?





The Healing Vitamin
Even with a healthy diet, you may be D-ficient


BY DIANE PETERS
Samar Elhamalawy didn’t know what was wrong with her little son. But when Mahmood was nine months old, he suddenly lost interest in walking. He reverted back to crawling, from standing and cruising along the couch. “He just started to deteriorate,” the Hamilton mother of two recalls. A few months later, she worriedly asked her family doctor why he had so few teeth. Then, at 14 months old, the little boy took two steps, fell down and broke his arm.

Within a month, Hamilton bone specialists diagnosed Mahmood with rickets, a bone-weakening disease caused by vitamin D deficiency.

Looking back a century, the slums of New York and London teemed with children whose weak, spindly limbs and bowed legs testified to their D deficiency. (Tiny Tim, the character in Charles Dickens’s A Christmas Carol, was a likely case.) The disease all but disappeared after the 1920s, when doctors realized it could be cured by sun exposure and farmers began fortifying milk with vitamin D.

But lately the malady has been making a comeback. That’s bad news, and not just for kids: Nowadays scientists are linking low levels of D to cancer, hypertension, diabetes, multiple sclerosis, osteoporosis and inflammatory bowel disease.

The rest of the article is here:

I've also seen it linked to higher rates of some forms of cancer... or something. I think that was also from Reader's Digest!

I think that was mainly if you get too much though.

The article did mention problems with overdosing, but suggested that studies show that, like everything else, massive doses would be necessary to overdose on D. I believe the article says something like 40,000 mg./day would be needed to od.

The suggested daily dosage is 4000 mg./day for those people in live in more northern climates, and perhaps 1000 mg./day for those who live in warmer areas.

But that is very important, geebob, and I thank you for reminding me of it!

I've heard that if you don't get any sun you'll get Vitamin D deficiency, and that it can lead to depression. I don't know how true it is, though; consult with nutrition expert Anthrogirl for more info on that.

The article was intimating this as well. Depression along with a lot of other problems.
And of course I live in the Great White North. Although we get a lot of sun in the winter, according to the article it isn't enough.


AG would be great to ask about this!

Thanks for the suggestion, BHN.

Overdosing is a concern, since Vitamin D is fat soluble and not water soluble like vitamin C.

That means overdosing Vitamin C is no problem, the excess will be washed out in the water.

Vitamin D is gonna get stored, and without proper care, high doses will cause toxicity. Don't be fooled with mega doses with these vitamins, the effects can be serious. E, D, and some others are this way.

Yes, the article addressed overdoses. But the amounts would have to be huge. They are recommending at the most 4000 mg./day, with an overdose level being 40,000 mg./day.
