Overview Liver and vitamin D contains the following summary
- Fact: A properly functioning liver is needed for the efficient activation of vitamin D in the body
- Fact: Liver diseases often result in lower levels of vitamin D
- Fact: Various pain relievers damage the liver function
- Fact: Lower levels of vitamin D result in osteoporosis and many other diseases
- Options with a poorly functioning liver appear to be:
- Increased vitamin D (example: 2X more vitamin D if Liver is 1/2 as efficient)
- Increase the response you get from vitamin D
- Increase sunshine / UVB,
- Get the response you get from the sun/UVB
- Consider supplementing with Iron - a patented Iron supplement appears to work very well
- Get prescription for active form of vitamin D (Calcitriol) which does not need the liver or kidney to get the benefits of vitamin D in the body
- Get Calcidiol which does not need the liver
- Use Topical Vitamin D - activation by the skin etc does not require the liver
Diabetes category starts with the following

The western diet high in fat and fructose may cause metabolic disorders and cardiovascular diseases.
To evaluate whether long-term daily vitamin D3 supplementation prevents hepatic steatosis and cardiovascular abnormalities and restores insulin sensitivity caused by fat diet in rats without vitamin D deficiency.
Three groups of rats were fed for 6 months with standard diet (SD), western diet (WD) or WD containing 23 IU/day/rat vitamin D3, respectively. Tail-cuff systolic blood pressure (SBP)measurements in conscious rats and transthoracic echocardiography were performed in basal condition, and after 3 and 6 months of diet. Hepatic steatosis and myocardial fibrosis were assessed in liver and cardiac tissues using standard methods. Serum insulin and 25(OH)D3 concentrations were determined using rat-specific ELISA kits. Insulin resistance was determined according to the homeostasis model assessment of insulin resistance (HOMA-IR) method.
Sixty-one per cent of hepatocytes in WD rats had steatotic vacuoles compared with just 27% in rats on a WD plus vitamin D3 (p < 0.05).HOMA-IR was reduced in rats with vitamin D supplementation compared with WD alone (19.4 ± 5.2 vs 41.9 ± 8.9, p < 0.05). Rat blood pressure and left ventricular mass were both reduced by vitamin D3 supplementation.
In animal models of liver and cardiovascular metabolic damage, the supplementation of vitamin D3 shows liver and cardio-protective effects.
