Do vitamin D supplements offer kidney-related benefits for individuals with high diabetes risk?
In the general population, low blood vitamin D levels have been associated with higher risks of various diseases, including type 2 diabetes and kidney disease.
Results of a study did not show a benefit of vitamin D supplements on kidney function,
About 43% of the study population was taking outside-of-study vitamin D, up to 1000 IU daily, at study entry, though. Among those who were not taking any vitamin D on their own, there was a suggestion for vitamin D lowering the amount of urine protein over time, which means that it could have a beneficial effect on kidney health. Additional studies are needed to look into this further.
vitamin D supplementation is popular, and it’s difficult for clinical trials of vitamin D supplementation to show a benefit if the population studied is not vitamin D deficient.
The majority of the study population had sufficient blood vitamin D levels and normal kidney function,Benefits of vitamin D might be greater in people with low blood vitamin D levels and/or reduced kidney function.
