A note about these recommendations
Every supplement below is selected based on clinical research supporting kidney function. These are not replacements for medical treatment — especially if you have chronic kidney disease (CKD). Always consult your nephrologist before starting any supplement, as some can affect kidney filtration rates.
⚡ Quick recommendation
If you try one thing: #1 Astragalus Root — the most researched herb for kidney support.
For a solid combo: #1 Astragalus + #2 Alpha Lipoic Acid + #6 Vitamin D3+K2
If you take statins: Add #3 CoQ10 — statins deplete CoQ10 which kidneys need.
