Vitamin D and Insulin
I found the following information in the July 2007 issue of the Nutrition Action Health Letter. I thought it may be useful information, so I am posting it for you.
"If you have high blood sugar, taking vitamin D and calcium may keep it from rising further. Researchers randomly assigned 314 people without diabetes to take either a daily placebo or both calcium (500 mg) and vitamin D (700 IU) every day for three years as part of a study designed to look at bone strength.
Among the 92 people who started the study with blood sugar levels in the high-but-not-diabetic range (100 to 125 mg/dL), those who took vitamin D and calcium had a smaller average rise in fasting blood sugar (0.4 mg/dL) than those who took the placebo (6 mg/dL). Insulin resistance also increased less in vitamin D and calcium takers.
Vitamin D and calcium had no impact on the blood sugar of the 222 people who had normal fasting blood sugar levels (less than 100 mg.dL) when the study began.
What to do: If you have higher-than-normal blood sugar, make sure you're getting enough calcium (1,200 mg a day) and vitamin D (1,000 IU a day) from food and supplements."
Discussion: Do you know what your blood sugar level is? When is the last time you had a check-up at the doctor? An ounce of prevention is worth a pound of cure.

Great information. Vitamin D deficiency is emerging as the epidemic of our time.
Since we got scared out of the sun in 1989 many Vita D deficiency disease have been on the rise.
http://www.vitamindcouncil.com/research.shtml for the cutting edge information on Vitamin D.
I believe we should work toward a totally Vitamin D replete population.
Let's get our public health officials on it!

Vitamins are great sometimes for your body and with the help of a positive mentality over the illness, can create a speedy recovery.

I was diagnosed with diabetes a few weeks ago, now hunting for information about vitamins and how they might help so thanks for this.

I was diagnosed with Type 2 diabetes about a year ago. I am not on medication. I tried 1200 IU vitamin D and 1400 mg Calicum, and it dropped my fasting glucose about 10%. I tried 2400 IU and got no improvement. I dropped back to 800 IU and my glucose levels increased. This is worth testing, but may not be same for everyone. Jim

According to today's recommendations, 700IU of D is a small amount... 1000-2000IU is safely recommended and the best absorbed is D3. which is the natural Vitamin D... Not the D2 usually found in multiple vitamins.

Some of the do's and don'ts in the diabetes we never been known has been give in this very informative post.
Every patient should keep these points in their mind, to lead a safe life with high blood sugar.

I found a blog post that makes an interesting argument that some of the studies showing lower Vit. D linked to increased mortality in osteoporosis and autoimmune disease are showing an effect of infection and Vit. D receptor disregulation rather than simple deficiency.
You won't find any research that shows vitamin D + calcium increases bone density above calcium alone. Blood levels of calcium, yes. But not bone density.
Many people with low 25D have high 1,25D which is a product of 25D
That argues against deficiency in some cases. And in favor of infection + occasionally dysregulation of the Vitamin D Receptor resulting in overproduction of
1,25D from 25D (which leads to low levels of 25D, which appears like deficiency)
bacteriality.com/2007/09/15/vitamind/
They say high levels of 25D deactivates the Vitamin D receptor based on molecular modeling, though. That part I question. How much D3 supplementation does it take to maximize cathelidicin production?
I cannot find an answer to that question, and it should be simple.

Creative and this information is useful.

I think that a lot of calcium intake as well as vitamin C is great for a person, especially for women. It has been proven that girls should start taking calcium supplements as early as 14.
