No Link Found Between Vitamin D and Kidney Stone Risk
Vitamin D is an essential nutrient that has been linked with reduced risk of a wide range of ailments but previous research has suggested that there may be a link between vitamin D supplementation and developing kidney stones. A new study suggests, however, that taking vitamin D does not increase the risk of kidney stones.
The study included 2,012 individuals who participated in the GrassrootsHealth data study. The researchers followed the participants for an average of 19 months, during which time 13 individuals reported developing kidney stones.
The researchers found no statistically significant association between vitamin D levels in the range of 20 to 100 ng/ml and kidney stones. However, they did find that older age, male gender, and a higher body mass index (BMI) were all associated with a higher risk of kidney stones.
They noted that people with a higher BMI need to take more vitamin D in order to achieve the same blood levels as people with a lower BMI. Previous research may have incorrectly identified vitamin D as the mechanism behind the increased risk of kidney stones, when it was actually due to higher BMI.
Researchers from the University of California, San Diego School of Medicine conducted the study. It was published online ahead of print in the American Journal of Public Health on October 17, 2013.
Previous studies have shown vitamin D to be associated with reductions in the risk of skin cancer, reducing the risk of osteoporosis,combating diabetes, and improving age related eye degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
