Creatine Monohydrate, Dose
At 32:10 · chapter starts 31:53
The final substantive topic is creatine monohydrate, and Norton is unambiguous: it's the most tested, safe, and effective sports supplement in the category, backed by thousands of studies. He traces the mechanism — creatine increases intramuscular phosphocreatine, which rapidly regenerates ATP during high-intensity exercise, improving performance, recovery, and lean mass — and notes that the lean mass gains are partly from water drawn into muscle cells, which is physiologically appropriate since muscle is mostly water.

On dosing, he outlines two equivalent strategies: a loading protocol (high dose for a week, faster saturation, higher GI risk) versus a steady 5g/day approach that achieves the same end state in 2–4 weeks with fewer side effects.

Norton adds that recent research suggests cognitive benefits, which he finds genuinely intriguing. The chapter closes with a quote from Dr. Mike Israetel: no supplement protocol, however refined, can outscience consistently hard training.
Creatine loading saturates stores in ~1 week
Loading creatine (higher doses for the first week) saturates phosphocreatine stores in about a week; taking 5g/day achieves the same result in 2–4 weeks.
