Low Vitamin D levels may be linked to early kidney disease, according to a new study.
Researchers found that those who were deficient in vitamin D were more than twice as likely to develop albuminuria, a type of protein in the urine that can be an early indication of kidney damage as healthy kidneys capture protein for use in the body.
“There have been a number of studies establishing a relationship between vitamin D levels and kidney disease,” said Thomas Manley, director of Scientific Activities for the NKF. “This study supports that relationship and shows that a low vitamin D level increases the likelihood of developing protein in the urine, even among a general population.”
Sunlight is the primary source of vitamin D for most people. However, researchers speculate that an increased skin cancer awareness and more indoor time may contribute to vitamin D deficiency in the general population. Secondary sources of vitamin D include supplements, certain sea foods, eggs and products fortified with vitamin D such as milk and orange juice.
It is unknown if vitamin D levels are a cause or condition of kidney damage. However, the research could bolster the case for more careful vitamin D monitoring and using vitamin D levels to identify individuals who may be at risk for developing kidney disease.
The study will be published in the July issue of the National Kidney Foundation’s (NKF) American Journal of Kidney Diseases (AJKD). For more information on the study, visit Renal Business Today.
