Summary
Layne Norton kicks off his supplement series with his "Mount Rushmore" of ergogenic supplements: creatine monohydrate, whey protein, and caffeine. He walks through why these three have stood the test of time for body composition, strength, and exercise performance while trendier options have faded, covering the research behind each one's effectiveness and safety profile.
Key Points
- Creatine monohydrate (3-5g daily) is the most well-researched supplement for strength, muscle, and even cognitive performance.
- Whey protein is the highest-quality protein supplement for muscle protein synthesis due to its leucine content and rapid absorption.
- Caffeine (3-6mg/kg bodyweight) improves endurance, strength, and power output with one of the most robust evidence bases in sports nutrition.
- Loading creatine (20g/day for 5 days) saturates stores faster but 3-5g daily reaches the same levels within 3-4 weeks.
- Creatine does not cause kidney damage in healthy individuals despite persistent myths.
- These three supplements have decades of safety data and consistent positive results across hundreds of studies.
Key Moments
Creatine cognition shines under stress — sleep deprivation, mental fatigue, high cognitive load
Layne Norton explains that creatine's cognitive benefits are most pronounced under conditions of stress like sleep deprivation, mental fatigue, or high cognitive workload. He notes you would need to eat almost 5 pounds of cooked beef daily to match a supplement dose since cooking destroys 50% of creatine bioavailability.
"So muscles aren't the only thing that use creatin in the phosphocreatin system. Your brain uses it too."
Caffeine optimal dose is 3-6mg/kg for performance — lowers perceived exertion
Norton details that caffeine's performance benefits require 3 to 6 milligrams per kilogram of body weight, higher than the dose needed for cognition and alertness. Caffeine improves max strength, power output, and crucially lowers perceived exertion so the same training feels easier.
"but most of the performance benefits are at a pretty high dose of caffeine for cognition and alertness. You can get by with a lower dose, but for actual performance benefits, you're around three to six milligrams per kilogram,"
Only 3 Tier 1 supplements in 30 years of research — creatine, whey protein, caffeine
Norton's Tier 1 classification is extremely restrictive, requiring decades of research with very consistent significant effects. Only three supplements qualify for body composition, strength, and performance: creatine monohydrate, whey protein, and caffeine. He notes there is a reason these have not fallen out of style in 30 years.
"creatin monohydrate, way protein, and caffeine. Yes, I know you're all very bored with those choices, but as I have said many times, there is a reason that these things have not fallen out of vogue or out of style in the last 30 years"
Creatine monohydrate is the gold standard — no other form improves on it
Norton emphatically states that creatine monohydrate saturates muscle cells to 100% capacity of creatine phosphate stores, and no alternative form of creatine can exceed 100%. This makes monohydrate the only form worth buying despite marketing claims for other versions.
"of their creatin phosphate stores is what you're targeting."
