Study Deep Dive: Creatine is SAFE

Creatine is SAFE, the verdict is in!

After decades of people claiming that creatine will wreck your kidneys, liver, & various other claims, a new study has put these myths to bed.

In my latest episode of the Dr. Layne Norton Podcast, I go DEEP on the most comprehensive dataset to date: a brand new meta-analysis by Kreider et al. (2025) which reviewed 250+ studies, covering over 26,000 participants, some lasting more than a decade, and examined nearly 50 potential side effects.

The verdict? Absolutely no evidence of harm.

I broke down the full paper, the methods, and what this means for athletes and everyday lifters in the latest episode of the podcast.
