You hit the gym. You scoop your creatine. You feel unstoppable.
Then your blood report lands.
Creatinine: HIGH.
eGFR: low.
And suddenly your brain screams one word — kidneys.
Breathe.
Hyderabad nephrologist Dr. G. Murali Mohan Reddy says: this is one of the most misread reports in modern fitness.
Your muscles store about 95% of the body's creatine.
When you supplement, that pool can swell by 20–35%.
And the body quietly converts part of it into… creatinine.
The same creatinine your lab measures to estimate kidney function.
So the number goes up.
eGFR drops.
But your kidneys? Still filtering perfectly fine.
A 2025 systematic review and meta-analysis confirmed it — a modest, transient rise in serum creatinine, with no real drop in filtration.
Dr. Reddy's protocol is almost boring in how simple it is:
That's it. No nephrologist nightmare. No early retirement from leg day.
A young user named Abhinav described the classic arc:
"My parents freaked out. So did I. Then a retest after a pause came back normal."
Before you scoop, do this:
If doubt remains, doctors can run a cystatin C test or a measured GFR — the proper way to settle the question instead of diagnosing failure from one shaky estimate.
Creatine isn't just gym fuel anymore.
A 2025 University of Kansas pilot gave Alzheimer's patients 20g a day for 8 weeks — and saw higher brain creatine plus shifts on cognitive tests.
Memory. Focus. Muscle. Energy.
This little white powder is quietly becoming one of the most studied supplements on Earth.
💡 The takeaway:
A scary number on a lab report isn't always a scary diagnosis.
Context beats panic. Every single time.
That's all for now!
