Overview Diabetes and vitamin D contains:
- 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
553 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
- 90% less T2 Diabetes in the group having lots of Vitamin D
- Appears that Magnesium helps both Prevention and Treatment
- Many diabetics would be better treated if Gut-Friendly Vitamin D were used

In this systematic review and meta-analysis of randomized controlled trials (RCTs), the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in diabetic patients are summarized. The following databases were searched up to December 2017: MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. The quality of the relevant extracted data was assessed according to the Cochrane risk of bias tool. Data were pooled using the inverse variance method and expressed as mean difference with 95% Confidence Intervals (95% CI). Heterogeneity between studies was assessed by the Cochran Q statistic and I-squared tests (I2).
Overall, 33 studies were included in the meta-analyses. Vitamin D supplementation were found to significantly reduce
- serum high-sensitivity C-reactive protein (hs-CRP) (WMD 0.27; 95% CI, - 0.35, - 0.20; p<0.001) and
- malondialdehyde (MDA) levels (WMD - 0.43, 95% CI - 0.62, - 0.25, p<0.001)
in diabetic patients. In addition, vitamin D supplementation were found to increase
- markers of nitric oxide (NO) release (WMD 4.33, 95% CI 0.96, 7.70),
- total serum antioxidant capacity (TAC) (WMD 57.34, 95% CI 33.48, 81.20, p<0.001) and
- total glutathione (GSH) levels (WMD 82.59, 95% CI 44.37, 120.81, p<0.001).
Overall, this meta-analysis shows that in diabetic patients, taking vitamin D had significant effects on hs-CRP and MDA levels, and significantly increased NO, TAC and GSH levels.
T2DM
NO increased in diabetics ( a good thing)
