Overview Diabetes and vitamin D contains the following
- 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
529 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

Diabetes, Metabolic Syndrome and Magnesium - many studies
- Step back to 1994. Suppose an epidemic struck the United States, causing blindness, kidney failure, and leg amputations in steadily increasing numbers.
Suppose that in less than a decade's time, the epidemic had victimized one out of every eight people
That epidemic is real, and its name is diabetes, now the nation's sixth leading cause of death.

To investigate the effect of single nucleotide polymorphisms (SNPs) of the key genes in vitamin D metabolic pathway on the serum 25(OH)D level after long-term vitamin D3 supplementation and provide a theoretical basis for rational vitamin D3 supplementation in diabetic patients with different genetic backgrounds.
Patients with type 2 diabetes (T2DM) who met the inclusive criteria were given 800 IU of vitamin D3 daily for 30 consecutive months. Serum 25(OH)D levels was measured at enrollment and every 6 months after enrollment. The average value of four-time measurements represented individual serum 25(OH)D level during vitamin D3 supplementation. Multiplex TaqMan genotyping was used to determine the distribution of eight candidate SNPs in genes of DHCR7, CYP2R1, CYP27B1, CYP24A1, and VDR, which are key genes in the vitamin D metabolic pathway, in diabetic patients.
At baseline, the average serum 25(OH)D level was 22.71 ± 6.87 ng/mL, and 17.9% of patients had a ≥30 ng/mL level. During supplementation, the level of 25(OH)D increased significantly at each time point, and the average 25(OH)D level increased to 30.61 ± 5.04 ng/mL; however, there were 44.6% of patients whose serum 25(OH)D levels were still below 30 ng/mL. In the patients with CYP27B1 (rs10877012) G/T genotype, 71.79% achieved sufficient level of 25(OH)D, which was significantly higher than the other two genotypes (P < 0.05). Compared with those with T/T genotype, the RR of the patients with rs10877012 for <30 ng/mL level was 0.544 (95% CI: 0.291-0.917), and the RR after adjusting age and outdoor activity was 0.560 (95% CI: 0.292-0.970).
The serum 25(OH)D level in patients with diabetes mellitus after long-term vitamin D3 supplementation is associated with CYP27B1 polymorphism. Patients with rs10877012 G/T allele have a better response to vitamin D3 supplementation.Type II diabetes 2 X more likely if poor Vitamin D Gene (CYP27B1) – Oct 2019
