For people with healthy kidneys, protein shakes are harmless in normal amounts. In CKD, high protein loads add filtration burden and can accelerate progression — and in dialysis, the opposite problem is common: patients need MORE protein, and shakes can help reach the 1.2 g/kg/day target. It's stage-dependent.
Healthy kidneys adapt to high protein — large cohorts show no CKD risk from high-protein diets. In CKD, KDIGO advises avoiding high protein intake (above ~1.3 g/kg/day); a shake on top of a normal diet can push intake there.
Dialysis is different: dialysis removes amino acids, and patients need 1.2 g protein/kg/day — shakes (renal-specific or whey in moderation) are a legitimate tool when appetite is poor and phosphorus/sodium in the shake is checked.
What to check in any shake: potassium and phosphorus additives (many 'mass gainers' are loaded), plus sugar. Renal-specific shakes exist for dialysis patients; whey in moderate doses is usually acceptable with monitoring.
