Items in both categories Diabestes and Vitamin K are listed here:


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 429 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

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.

Overview Vitamin K and Vitamin D contains the following summary

Vitamin K2 is similar to D3 in many ways

  1. Both vitamins were initially confused with its lesser form (D2 ==> D3, K1 ==> K2)
  2. Both vitamins appear to influence health in large number of ways
  3. Both vitamins in the body are about 1/10 that of a century ago
    Example: Grass-fed beef has a lot more K2, D3, and Magnesium
  4. Need very little of both vitamins: <1 milligram daily
  5. When Vitamin D3 is increased, it appears that Vitamin K2 should also be increased
  6. Vitamin K2 understanding and research is about 20 years behind that of Vitamin D3
    One of the reasons: No simple blood test for K2 as of July 2018


Diabetes mellitus and pre‐diabetes are prevalent endocrine disorders associated with substantial morbidity and premature mortality. Vitamin K is known to have several beneficial effects on complications of diabetes and pre‐diabetes. However, systematic consolidation of evidence is required to quantify these effects in order to inform clinical practice and research. A systematic search in PubMed, Scopus, Embase, ProQuest, and Google Scholar databases was undertaken from database inception up to October 2018 to evaluate functional roles of different forms of vitamin K on diabetes and pre‐diabetes. From 3,734 identified records, nine articles met the inclusion criteria and were evaluated.
Vitamin K supplementation was found to be associated with significant reductions in

  • blood glucose (six studies),
  • increased fasting serum insulin (four studies),
  • reduced hemoglobin A1c (three studies),
  • reduced homeostatic model assessment‐insulin resistance index (HOMA‐IR) (two studies), and
  • increased ß‐cell function (two studies)

in diabetic animal studies. Following 2‐hour oral glucose tolerance test, vitamin K supplementation was observed to be effective in reducing blood glucose and insulin levels in the pre‐diabetic population. However, no evidence of effect was observed for fasting blood sugar, insulin, HOMA‐IR, and homeostatic model assessment‐β‐cell function index (two studies).
A statistically significant effect was also noted with vitamin K in improving

  • dyslipidemia (three studies) as well as
  • oxidative stress and inflammatory markers (five studies)

in diabetic animals. In conclusion, clinical trials and animal studies confirm that vitamin K supplementation may improve both clinical features and complications of diabetes and pre‐diabetes. However, quantification of clinical efficacy in the pre‐diabetic population and among individuals with comorbidities requires further investigation.
