**TL;DR:** Creatine doesn't harm kidneys in healthy athletes, studies show no significant issues

So many people are spouting this myth about creatine being a kidney killer, but let's be real. A ton of studies, like the one from *Journal of Sports Nutrition* (2008), show no adverse effects on kidney function in healthy athletes taking creatine. They even tracked biomarkers for renal health over 12 weeks with doses up to 20g. No significant changes! If you got pre-existing kidney issues, sure, you should be careful, but healthy dudes don't need to stress over creatine! It's not some magic poison, it's just a solid supplement for gains. Don't let the myths hold u back from hitting those PRs, fam.

  Omg, I love creatine! I started taking it last year, and my lifts improved so much! I really think it's been a game changer for my strength. And guess what? My kidney function is still all good! If you're unsure, just make sure to drink enough water. Hydration is key, people!

  The myth around creatine and kidney damage stems from misunderstandings about how our bodies process it. Creatine is naturally occurring in our muscles and has been studied extensively, showing that healthy individuals can safely consume it without adverse renal effects. In fact, numerous peer-reviewed studies, including those in the *Journal of Sports Nutrition*, support this. If you're healthy and not at risk for kidney issues, there's really no reason to fear creatine.

    I hear this all the time, but honestly, as someone who lifts only when I can squeeze it in, I think people worry too much. I just focus on my overall health and fitness. If creatine helps you hit those PRs and you're healthy, go for it. Just be sensible about your intake and listen to your body.

    Facts, creatine is not the villain people make it out to be. I've been lifting for years and took creatine for most of that time, my kidney function is perfectly fine. It's all about how you use it and staying within a reasonable dose. Plus, it can really help with strength gains and recovery.

    Yeah, I mean, if creatine is a kidney killer, then I guess I'm already dead. I took 10g a day for 3 years, and I'm still here, doing my best to push that 1RM. But seriously, there are way too many myths in the gym community, it's exhausting. Don't let these scare tactics keep you from trying something that could really help you progress.
