Frequently asked questions
What is a kidney complex capsule?
'Kidney complex' is a UK marketing term for daily capsules sold as kidney support. Formulas vary widely — some are kidney-conscious multivitamins, others are herbal blends (cranberry, dandelion, juniper, nettle) marketed for urinary or 'cleansing' use. For people with CKD, only the kidney-conscious multivitamin category is appropriate without medical supervision.
Are kidney complex capsules safe in CKD?
Only if the formula is kidney-conscious. Safe formulas leave out high-dose vitamin A retinol, added potassium, phosphate and magnesium, and avoid known nephrotoxic herbs (e.g. aristolochic acid). Herbal-blend kidney complexes are generally not recommended in CKD without renal-team approval.
What ingredients should a kidney complex capsule contain?
Evidence-based ingredients include vitamin D3 (commonly low in CKD), B-vitamins (B1, B2, B6, B12, folate) and moderate vitamin C. Kidney Vitality combines these in kidney-conscious doses without any added retinol, potassium, phosphate or magnesium.
Which ingredients should I avoid in a kidney complex?
Added retinol (vitamin A) above 800 µg, added potassium, added phosphate, added magnesium, large vitamin C doses, juniper berry, parsley extract, dandelion root in high doses, and any product containing aristolochic acid. These are flagged by the British Dietetic Association Renal Nutrition Group and KDOQI 2020.
How many kidney complex capsules per day?
Most kidney-conscious capsules are taken once daily with food. Kidney Vitality is one capsule per day. Always follow label instructions and do not exceed the recommended dose, especially if you take other vitamin or mineral supplements.
Where can I buy kidney complex capsules in the UK?
Kidney complex products are sold across UK high-street pharmacies, supermarkets and online. Kidney Vitality is manufactured in the UK (BRCGS / NSF GMP / Halal certified) and available directly from kidneyvitality.co.uk with optional monthly delivery.
Is Kidney Vitality a kidney complex?
Yes — Kidney Vitality is a UK-formulated kidney complex capsule designed by a Consultant Nephrologist for adults who want a kidney-conscious daily multivitamin. It is not a medicine and is not intended to treat kidney disease.
