Dietary sources and typical intake

Creatine is a hot subject right now, but I’m guessing you might not know as much about it as you could. Well step into a new creatine masterclass with our friends from Qualia. This episode shows you why it is not just for muscle, but one of the most powerful and well studied upgrades for brain energy, metabolism, sleep resilience, and long term human performance. You will learn how creatine supports mitochondria, buffers ATP, reduces cravings, and helps you think, train, and recover with more energy instead of relying on willpower.

Host Dave Asprey sits down with Greg Kelly for a deep, practical masterclass on creatine and energy biology. Greg Kelly is a naturopathic physician, functional medicine expert, and longtime researcher in supplements and nootropics. He has spent decades studying creatine, mitochondrial function, cognition, and performance, and has contributed to peer reviewed research while working directly with athletes, clinicians, and high performers. 

Together, Dave and Greg break down how creatine works at the cellular level, why it matters for cognition, emotional regulation, and metabolism, and how it supports the brain and body during stress, sleep deprivation, dieting, and recovery. They explore neuroplasticity, ATP production, magnesium, methylation, and why energy availability drives discipline, focus, and resilience more effectively than willpower alone. They also explain why creatine matters for women, aging adults, and people dealing with fatigue or obesity, and how creatine supports brain function even when muscle mass is low. 

This conversation connects bodybuilding research with modern longevity science, nootropics, functional medicine, and sleep optimization. Dave and Greg also expose why creatine quality matters, how contaminants can impair mitochondrial function, why some products fail label claims, and how to choose forms that absorb better and cause less bloating. Practical strategies like dosing, timing, stacking with magnesium, and using creatine with hot coffee are all covered, including why Dave uses it with Danger Coffee as part of his Smarter Not Harder approach. 

You’ll Learn: 

• Why creatine acts as an ATP buffer for both muscles and the brain 

• How mitochondria drive cognition, metabolism, and emotional regulation 

• The real dosing debate from low daily maintenance to higher cognitive doses 

• Why women often need more creatine than men 

• How creatine supports performance during sleep deprivation and sleep debt 

• The link between magnesium, creatine phosphate, and ATP production 

• How methylation and TMG relate to creatine synthesis and timing 

• Why creatine can reduce cravings by improving cellular energy 

• How low quality creatine and contaminants can damage mitochondrial function 

• When creatine matters most for longevity, resilience, and human performance
