What is the purpose of a renal vitamin for kidney dialysis patients?

renal vitamins

People on dialysis take a special renal vitamin preparation that contains B vitamins with extra folic acid and a limited amount of vitamin C. There are several reasons why dialysis patients take renal vitamins:

  • to replace vitamins removed during each dialysis treatment
  • the dialysis diet is inadequate in vitamins due to limits on fruits, vegetables and foods like milk, whole grains, nuts seeds and legumes
  • a limited variety of foods and poor appetite contributes to nutrient deficiencies
  • adequate amounts of folic acid, vitamin B12, and vitamin B6 are required to make red blood cells and prevent anemia
  • vitamin deficiencies increase risk for infection

Examples of renal vitamins are Dialyvite®, Nephrocaps®, Nephrovite®, Nephplex®, and Renaltab®. Some brands require a prescription and others are available over the counter. Kidney doctors or renal dietitians usually make recommendations on which renal vitamin to take.
