Frequently asked questions
What is the safest kidney supplement in the UK?
The safest UK kidney supplement is one designed for CKD: vitamin D3, B-complex and moderate vitamin C, with no added retinol, potassium, phosphate or magnesium, and no nephrotoxic herbs. Kidney Vitality is formulated to those rules and reviewed by a UK Consultant Nephrologist.
Do I need a kidney supplement if I have CKD?
Many people with CKD benefit from vitamin D and B-complex support, particularly on restricted-protein diets or dialysis. Your renal team or GP can advise based on your bloods and CKD stage. A kidney-conscious daily multivitamin is a safer default than a high-street product.
Which vitamins should I avoid with kidney disease?
Avoid high-dose vitamin A (retinol > 800 µg/day), large vitamin C doses (above 100–200 mg/day), and any added potassium, phosphate or magnesium in supplement form. See our 'vitamins to avoid in kidney disease' guide for the full list and the evidence.
Can I take Kidney Vitality with my prescribed renal vitamins?
If your renal team has prescribed a renal multivitamin (such as Renavit or Dialyvit), check before adding any over-the-counter product. Kidney Vitality is designed as a standalone daily supplement for adults not on prescribed renal vitamins.
Is herbal kidney tea (nettle, dandelion, parsley) safe in CKD?
Generally no in moderate to advanced CKD: nettle and dandelion are high in potassium and act as diuretics, parsley extracts have anecdotal nephrotoxicity reports, and any 'kidney cleanse' tea should be discussed with your renal team first.
How do I choose between UK kidney supplements?
Read the label, not the marketing. Look for: no added retinol, no added potassium, no added phosphate, no added magnesium, moderate vitamin C, vitamin D3 included, UK GMP manufactured, and ideally clinician-reviewed.
