VitaminDWiki had wondered for 8 years why Diabetes seemed to consume Vitamin D.
It appears that Insulin decreases the amount of vitamin D which gets to the blood

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 540 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

Risk factors for COVID-19 patients with poorer outcomes include pre-existing conditions: obesity, type 2 diabetes mellitus, cardiovascular disease (CVD), heart failure, hypertension, low oxygen saturation capacity, cancer, elevated: ferritin, C reactive protein (CRP) and D-dimer. A common denominator, hyperinsulinaemia, provides a plausible mechanism of action, underlying CVD, hypertension and strokes, all conditions typified with thrombi. The underlying science provides a theoretical management algorithm for the frontline practitioners.

Vitamin D activation requires magnesium.
Hyperinsulinaemia promotes:

  • magnesium depletion via increased renal excretion,
  • reduced intracellular levels,
  • lowers vitamin D status via sequestration into adipocytes and
  • hydroxylation activation inhibition.

Hyperinsulinaemia mediates thrombi development via:

  • fibrinolysis inhibition,
  • anticoagulation production dysregulation,
  • increasing reactive oxygen species,
  • decreased antioxidant capacity via nicotinamide adenine dinucleotide depletion,
  • haem oxidation and catabolism,
  • producing carbon monoxide,
  • increasing deep vein thrombosis risk and pulmonary emboli.

Increased haem-synthesis demand upregulates carbon dioxide production, decreasing oxygen saturation capacity. Hyperinsulinaemia decreases cholesterol sulfurylation to cholesterol sulfate, as low vitamin D regulation due to magnesium depletion and/or vitamin D sequestration and/or diminished activation capacity decreases sulfotransferase enzyme SULT2B1b activity, consequently decreasing plasma membrane negative charge between red blood cells, platelets and endothelial cells, thus increasing agglutination and thrombosis.

Patients with COVID-19 admitted with hyperglycaemia and/or hyperinsulinaemia should be placed on a restricted refined carbohydrate diet, with limited use of intravenous dextrose solutions. Degree/level of restriction is determined by serial testing of blood glucose, insulin and ketones. Supplemental magnesium, vitamin D and zinc should be administered. By implementing refined carbohydrate restriction, three primary risk factors, hyperinsulinaemia, hyperglycaemia and hypertension, that increase inflammation, coagulation and thrombosis risk are rapidly managed.
