Do I require daily Vitamin supplementation if I have Chronic Kidney Disease?
‘Can the kidney diet provide your complete nutritional needs or do you require daily vitamin supplementation? Here, the Kidney (Renal) Dietitians discuss vitamins and chronic kidney disease’
Vitamins are substances needed by your body to help carry out special functions. Vitamins are divided into two categories;
Vitamins play a part in controlling the body’s ability to burn fat and sugar for energy, and build proteins for growth. If vitamins are deficient, these reactions are not properly coordinated, and may cause, muscle weakness, fatigue and nerve pain. Following a balanced diet is the preferred way to get the recommended amount of these vitamins, however patients with kidney disease often cannot get enough of some vitamins,
Reasons include:
Due to the above, patients with Chronic Kidney Disease (CKD) may require a daily vitamin supplement as well as a balanced, nutrient dense kidney diet.
Special renal vitamins are usually prescribed to patients to provide the extra water soluble vitamins needed. Discuss your requirement for vitamin supplementation with your Kidney (Renal) Dietitian.
Dietary Folic Acid (Folate) intake may be suboptimal due to;
Discuss your requirement for folic acid (folate) supplementation with your Kidney (Renal) Dietitian.
Vitamin D helps your body to absorb calcium and phosphate and regulates the production of parathyroid hormone (a hormone that controls bone turnover). In CKD the kidney loses the ability to make active vitamin D. Supplementation with a special active vitamin D may be necessary. This is determined by blood levels of calcium, phosphate and parathyroid hormone (PTH). Supplementation with native Vitamin D (inactive form) may also be required. Discuss the need for vitamin supplementation with your Kidney (Renal) Dietitian.
Yes, when the kidneys are not able to eliminate excess vitamins from your body they can build up to toxic levels, this is of particular concern for Vitamin A (fat soluble vitamin), which is contained in many over the counter multi-vitamin preparations.
Also, Vitamin C breaks down in the body into a crystal called oxalate. Healthy kidneys remove extra oxalate, but dialysis is much less effective. A build up of oxalate can cause bone and joint deposits and pain.
Only use the vitamin supplement approved by your Kidney (Renal) Dietitian.
Do not take an over the counter multi-vitamin supplement.
