The Claim
Healthy Japanese kidney donors were found to have an average of 685,000 ± 242,000 non-sclerotic glomeruli per kidney, providing direct evidence of nephron numbers in living humans without chronic kidney disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists counted the tiny filters in healthy Japanese people's kidneys and found there are about 685,000 on average, giving us the first clear picture of how many filters normal human kidneys have.

What the research says
1 studyStudy: Dietary Protein Intake and Single-Nephron Glomerular Filtration Rate
The study directly gives the number of healthy kidney filters (glomeruli) in Japanese donors, which matches the claim exactly, so it supports it.
