Vitamin D Eased Fatty Liver and Blood Sugar Problems in Obese Rats

Key Insight

This animal study suggests vitamin D may be linked to better liver and blood sugar health in obesity.


Junk food fed rats developed fatty liver, insulin resistance, and inflammation, much like people on a poor diet. Weekly vitamin D cut their food intake and weight gain, and improved blood sugar control and liver fat. It also calmed inflammation markers in the liver. This was rats, so it does not prove the same effect in people.
