In this in-depth conversation, Dr. Peter Attia sits down with Layne Norton, PhD — a powerhouse in nutritional science and strength coaching. At one point in the conversation, they arrive at the topic of creatine and go deep on one of the most studied supplements in existence.
If you think creatine is just about bulking or gym culture, think again. This episode is a masterclass in how creatine impacts everything from strength and lean mass to brain health, metabolism, and even aging.
But it doesn’t stop there. Layne and Peter also dig into evolving views on protein intake, energy restriction, and how to optimize fat, fiber, and overall diet based on actual data, not dogma.
We’re just focusing on a single clip, but we encourage you to watch the full episode.
Why This Matters:
At Clay, we see similar patterns: people under-consuming protein, overlooking creatine, and chasing restrictive diets that ignore their actual biology. Creatine is one of the few supplements we consistently recommend — not just because it helps build strength and lean mass, but because the research shows benefits for cognition, aging, and mitochondrial health.
This episode clears the air. If you’re serious about performance, metabolism, or long-term vitality, this conversation is worth your time.
