A recent randomized controlled trial published in BMC Nephrology found no improvement in various markers of cardiovascular function in patients with chronic kidney disease on dialysis after supplementing with vitamin D.
Chronic kidney disease (CKD) describes loss of function of the kidneys over a minimum of three months. The disease progressively becomes more severe over time. People with severe CKD need treatment known as dialysis to keep them alive and healthy. Dialysis is a process that artificially removes waste and excess water from the blood in people with impaired kidney function.
