Tufts-Harvard study builds vitamin D's anti-diabetes potential

Daily supplements of vitamin D may boost the function of the cells in the pancreas that produce insulin, says a new study from Boston-based researchers that supports the potential role of the vitamin for pre-diabetics.

A daily 2,000 International Units (IU) dose of vitamin D3, also known as cholecalciferol, was associated with a 25 percent improvement in the functioning of beta cells in the pancreas, according to findings published in the American Journal of Clinical Nutrition.

Vitamin D is VERY important.

5k a day for me. No problemo.

Careful now. Vitamin D is a fat soluble vitamin, meaning, you take this, it doesn’t just wash out via pee like vitamin C.

“excerpt follows”

Because the body has a built in mechanism for preventing toxicity with vitamin D produced in the skin, there is no risk of vitamin D toxicity due to ultraviolet-B (UVB) exposure - whether from the Sun or a tanning bed.

Supplemental vitamin D bypasses this built-in protection and, if excessive amounts are consumed over a period of time, 25(OH)D blood levels can reach a point where toxicity is possible

Yes, I agree that the sun is the best source of D. In fact, there have been some questions as to whether taking supplements somehow makes the body’s natural vitamin D production from sunlight less effective.

However, the MDR amount of D (400 IU) is now thought to be way too low and will probably be increased by the “experts” soon. I don’t think that 2,000 IU a day would cause problems with toxicity, but everyone does need to be aware that we can OD on D. ;-)

Thanks, Pining.

There are simple finger prick home blood tests that can be ordered online to test for levels of D.

Fat soluble also means that you need to ingest fat at the time you take the supplement for it to be properly absorbed.

FReepmail me if you want on or off the diabetes ping list.

My intake is now 3,000 units, down from 4,000 and a temporary spurt to 6000 during the month when there was flu present. At levels above 2,000 units a day, the hacking and coughing every morning to clear my chest disappears. The mucous flow is altered somehow.

In June I had a kidney stone, out of the blue with no warning and no known proximate cause. When reading on the subject, there was one one glaring possible kidney stone cause listed...... excessive Vitamin D.

Does anyone know of the relation of Vitamin D and Kidney stones?

As a Diagnosed Type 2 diabetic, possibly prediabetic depending on who you believe, the intake of Vitamin D would seem to have no effect on my condition

5K of D₃ for me too. Going on five years now.

Guess how long it's been since I was sick?

Thank God.

But according to that article, you’d have to take between 40,000 and 2,000000 IU of Vitamin D to be toxic! That’s pretty hard to do. Maybe the only way someone would do this is to eat a jar of those delicious gummy Vitamin D candies.

Hey ...chuck;

"IMHO, this article is kinda out of place being posted on a politically conservative board. What does this article have to do with conservative politics?"

AND, you posted, 'why?'

[Eric in the Ozarks]

Thanks for putting this info on one of the important boards I check every day. I'm taking 1000 mgs of metformin twice a day, getting daily exercise and have never had a weight problem no matter what I eat.
