Kidney Vitality is formulated using renal nutrition principles (NICE NG203, KDIGO 2024, KDOQI 2020, BDA Renal Nutrition Group), at moderate doses, in active forms where relevant, and without added potassium, magnesium, phosphorus or iron. All nutrient claims use EFSA-authorised wording. It is a food supplement, not a medicine.
Key recommendation: Renal nutrition principles — moderate doses, no megadose vitamin A.

Active forms of key vitamins
Folate as L-methylfolate (5-MTHF) — the circulating, metabolically active form.
Vitamin B12 as methylcobalamin — an already-active coenzyme form.
Vitamin B6 as pyridoxal-5-phosphate (P5P) — the active coenzyme form.
Vitamin B2 as riboflavin-5-phosphate (R5P) — the phosphorylated active form.
Active forms bypass enzymatic conversion steps that some adults perform less efficiently. They are not claimed to treat any medical condition.
Kidney Vitality is a daily multivitamin developed by a UK Consultant Nephrologist using renal nutrition principles. It contains no added potassium, magnesium, phosphorus or iron, and no herbal blends. See the formulation.
Why no added potassium, magnesium, phosphorus or iron
These four minerals are routinely restricted or carefully titrated under renal team supervision. Adding them to an over-the-counter multivitamin can complicate that work. Iron status in particular is monitored individually in renal practice; routine supplementation outside that context is not appropriate. See /why-no-potassium-magnesium-phosphorus for the full explanation.
EFSA-authorised nutrient function wording
All nutrient claims on Kidney Vitality use wording from the EU Register of nutrition and health claims (retained in UK law). Examples include: vitamin D contributes to the normal function of the immune system; vitamin B12 and folate contribute to normal homocysteine metabolism; vitamin C contributes to the protection of cells from oxidative stress. See /approved-health-claims for the full list.

Kidney Diet & Nutrition Considerations
Diet is one of the most powerful tools you have to look after your kidneys. UK renal guidance points to a Mediterranean-style, reduced-salt pattern: plenty of vegetables, lower-potassium fruit, whole grains, sensible protein, beans and pulses in moderation, oily fish and olive oil. Personal targets — for potassium, phosphate, protein and fluid — should be set by your renal team based on your bloods.
Foods to prioritise
Vegetables, lower-potassium fruit and whole grains
Sensible portions of fish, eggs, chicken or tofu
Olive oil and unsalted nuts in small amounts
Foods to limit
Added salt and ultra-processed foods
Phosphate additives in processed meats and ready meals
Sugary and energy drinks
Potassium, phosphate and protein needs vary between individuals — please confirm personal targets with your renal team or dietitian. Browse the Kidney Diet Hub for more guides in this cluster.
Frequently asked questions
What evidence base underpins Kidney Vitality?
Kidney Vitality is formulated using renal nutrition principles drawn from UK and international guidance — NICE NG203 (chronic kidney disease assessment and management), KDIGO 2024 CKD guideline, KDOQI 2020 Nutrition in CKD, and the British Dietetic Association Renal Nutrition Group. Each ingredient is included at moderate, evidence-aligned doses; nutrient claims use EFSA-authorised wording only.
Why active forms of key vitamins?
Active forms (5-MTHF folate, methylcobalamin B12, pyridoxal-5-phosphate B6 and riboflavin-5-phosphate B2) are the metabolically usable forms of those vitamins. They bypass the conversion step that some adults perform less efficiently. They are not claimed to treat any condition; they simply provide the vitamin in its already-active form.
Does Kidney Vitality treat, cure or prevent kidney disease?
No. Kidney Vitality is a daily food supplement, not a medicine. It is not intended to treat, cure or prevent kidney disease, slow CKD progression, or improve kidney function. People living with kidney disease need individualised advice from their renal team.
Why no megadose vitamin A?
Retinol (vitamin A) is fat-soluble and not removed by dialysis; high doses can accumulate. Renal dietitians routinely flag added retinol on multivitamin labels. Kidney Vitality contains no added vitamin A.
Where can I see the references?
Each guide on this site lists the underlying guidance documents (NICE, KDIGO, KDOQI, BDA). The medical reviewer is Professor Mohammed Mahdi Althaf, Consultant Nephrologist (GMC 7216325).
What foods are good for kidney health?
A Mediterranean-style, mostly plant-based, reduced-salt diet is the most consistent evidence-based pattern for kidney health. Build meals around vegetables, lower-potassium fruit, whole grains, fish, eggs or tofu, beans and pulses in moderation, and olive oil.
Nutritional challenges in kidney disease
Many people living with kidney disease have to limit foods because of potassium, phosphate, diabetes, dialysis, appetite changes or simply the time it takes to cook from scratch every day. That can make it harder to keep daily nutrition balanced — particularly for vitamins and minerals that food alone may not fully cover.
Kidney Vitality is a UK-formulated daily nutritional support product designed by Consultant Nephrologist Professor Mohammed Mahdi Althaf with renal nutrition in mind from the start. It keeps doses moderate, leaves out added potassium, phosphate and magnesium, and avoids megadose vitamin A — sitting alongside a kidney-friendly diet, not replacing it.
