Creatine cognitive and clinical findings

The Dr. Layne Norton Podcast is back with the start of a brand-new Supplement Series! In Episode 22, Layne kicks things off by diving deep into his Tier 1 supplements — the ones with the strongest scientific evidence for real-world benefits in performance, body composition, strength, recovery, and even cognition.

This episode covers the true MVPs that Layne considers essential (or close to it) for most people training hard:

Creatine Monohydrate — Why it's called the most effective ergogenic aid ever, how it boosts lean mass, strength, repeated sprint/power performance, and even helps cognition (especially under stress like sleep deprivation). We bust myths about kidneys, water retention, and non-responders, plus practical dosing (5 g/day, loading optional).

Whey Protein — The gold-standard for hitting leucine thresholds and maximizing muscle protein synthesis. How it supports lean mass gains, preserves muscle in a deficit, improves recovery and training volume over time — and why total daily protein matters way more than perfect timing.

Caffeine — One of the most reliable acute performance boosters out there. It cranks up strength, power, endurance, repeated sprints, alertness, and reduces perceived effort — especially when fatigued. We cover optimal dosing (3–6 mg/kg), timing, habituation, sleep trade-offs, and who should be cautious.

Layne breaks down the mechanisms, key meta-analyses, practical takeaways, dosing/timing strategies, safety profiles, and who might need to be careful with each one. No hype, no BS — just evidence-based insights to help you cut through the supplement noise.
