If you've ever wondered whether a renal vitamin is "just a normal multivitamin in different packaging" — the answer is no. There are five concrete differences that matter clinically.
1. No vitamin A (or very little)
Standard multivitamins typically include 800 µg vitamin A. Renal vitamins usually omit it because it accumulates in CKD.
2. Higher folate, B6 and B12
Water-soluble B vitamins are lost during dialysis and are commonly low in advanced CKD. Renal vitamins include them at therapeutic doses.
3. Modest vitamin C (never megadose)
60–90 mg, not 1000 mg. High-dose vitamin C contributes to oxalate stone risk and is restricted in CKD.
4. Vitamin D often included or recommended separately
People with CKD activate dietary vitamin D less efficiently. UK renal teams often prescribe vitamin D directly.
5. No potassium, no phosphate, low magnesium
The three minerals most commonly restricted in CKD are absent or minimal in true renal vitamins.
What about Kidney Vitality?
Kidney Vitality is a non-prescription, kidney-conscious daily supplement built around the same five principles. It's not a replacement for a prescribed renal vitamin if your renal team has given you one.
