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

BACKGROUND:
The western diet high in fat and fructose may cause metabolic disorders and cardiovascular diseases.
OBJECTIVE:
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.
METHODS:
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.
RESULTS:
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.
CONCLUSION:
In animal models of liver and cardiovascular metabolic damage, the supplementation of vitamin D3 shows liver and cardio-protective effects.
