Type 2 Diabetes is closely associated with our daily diets and has become a global health problem with an increasing number of patients. Recent observational and randomized studies on vitamin D3 suggested that higher plasma 25-hydroxyvitamin D3 [25(OH)D3] concentrations and more vitamin D3 intake are associated with lower risk of type 2 diabetes, which is characterized by postprandial hyperglycemia due to inappropriate glucose stimulated insulin secretion (GSIS) and its age-dependent increase of onset. However, rapid action of dietary vitamin D3 on the postprandial glucose profile has not been analyzed. When vitamin D3 is orally ingested in mice aged 12-14 weeks during an oral glucose tolerance test (OGTT), the serum glucose profile was not changed. In contrast, when OGTT was performed with old mice aged 30-34 weeks, the glucose profile was dramatically improved with increased insulin secretion, suggesting that orally ingested vitamin D3 potentiated GSIS in aged mice. Interestingly, there was also a significant increase in plasma GLP-1 in these aged mice. Our results suggest that orally ingested dietary vitamin D3 in aged mice improves glucose metabolism as a GLP-1 enhancer.

- Overview Diabetes and vitamin D contains the following summary
- Diabetes is 5X more frequent far from the equator
- Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
- Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
- Sedentary people get less sun / Vitamin D
- Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
- Elderly get 4X less vitamin D from the same amount of sun
Elderly also spend less time outdoors and have more clothes on
- All items in category Diabetes and Vitamin D
443 items: both Type 1 and Type 2
Vitamin D appears to both prevent and treat diabetes
- Appears that >2,000 IU will Prevent
- Appears that >4,000 IU will Treat , but not cure
- Appears that Calcium and Magnesium are needed for both Prevention and Treatment
- which are just some of the vitamin D cofactors
