Moderate protein intake (0.8g/kg/day) — excessive protein worsens proteinuria
High protein intake increases glomerular hyperfiltration and proteinuria
Evidence-Backed Supplements
When High

Questions to Ask Your Doctor
- Does my proteinuria indicate kidney disease, and should I have a 24-hour urine collection for accurate measurement? 24-hour collection is gold standard; spot protein/creatinine ratio is a convenient alternative.
