The Truth About Creatine: Myths, Teen Safety, and What to Buy

In this episode, Zach Guiser and John Tropeano kick things off with John's taper anxiety for his upcoming Ironman before diving into the wild NBA betting scandal involving Terry Rozier, Chauncey Billups, and a secret poker ring with characters like "Albanian Bruce".

This leads to the main topic: a deep dive into supplements. Zach lays down the single most important rule—the FDA does not regulate supplements —and explains why athletes must look for third-party testing labels like NSF Certified for Sport or Informed Sport to avoid banned substances.

From there, they focus on creatine, breaking down:

• How it works for explosive energy (the phosphocreatine system) .

• If it works (Yes, for power/strength, but the effect size is small).

• The myths vs. facts on kidney safety (creatinine vs. cystatin C) and hair loss.

• The big question: Should adolescents take it? They review the limited research and land on the ISSN's stance: it's only for mature athletes who have already mastered their diet, sleep, and training .

• What to buy: Stick to basic creatine monohydrate and avoid ineffective gummies.
