It is well known that vitamin D has a profound effect on calcium and bone metabolism, but its influence on other organs (extraskeletal effect) has been proposed. Consistently, vitamin D deficiency is associated with an increased incidence of various diseases, including type 1 and type 2 diabetes, as reported by many observational studies. However, there has been no consensus on whether vitamin D deficiency is a causative factor in the incidence of diabetes mellitus. There have been no randomized controlled trials (RCTs) aimed at preventing the onset of type 1 diabetes with vitamin D intake. In addition, the results of RCTs evaluating the preventive effect of vitamin D supplementation on type 2 diabetes development have been inconsistent. The recent observational studies, randomized controlled trials, and meta-analyses are confirming that vitamin D or active vitamin D administration is effective in preventing the incident of type 1 and type 2 diabetes.

Conclusion

Observational studies have shown that vitamin D/cod liver oil intake in the infancy period may be effective in prevent­ing the onset of type 1 diabetes. In addition, vitamin D used as adjunctive therapy with insulin may be associated with a protective immunologic effect and slow decline of residual beta cell function in patients with new-onset type 1 diabetes.
RCTs and meta-analyses showed that vitamin D/active vitamin D administration is slightly effective in prevent­ing type 2 diabetes development. Based on these results, the American Diabetes Association guidelines 2024 have adopted a policy of “recommending vitamin D and active vitamin D administration for patients with prediabetes to prevent type 2 diabetes development’'. The results of RCT in prediabetes adults with reduced basal insulin secre­tion, which may provide additional vitamin D benefits, are warranted.
However, prescribing of vitamin D/active vitamin D with delusive belief should be avoided. After prescribing them, we must follow up patients with attention to the appearance of side effects.

VitaminDWiki – 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 538 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
Diabetic Epidemic

• 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.
