Fact check: Is there research behind "cordyceps, reishi and astragalus protect the kidneys and lower creatinine"?

The supplement category most often sold to kidney patients in Asia.

Fact check: "Every kidney patient must strictly limit potassium — no bananas, tomatoes or potatoes." Is that true?

The most widely shared rule in patient groups — yet KDOQI 2020 and KDIGO 2024 actually recommend individualising potassium to blood levels. We separate CKD 1–3, CKD 4–5, dialysis and transplant, explain who needs restriction and how much, and what blanket restriction can cost.
