How does creatine affect the body and health?
In this episode of Health Recoded, we break down the science behind creatine, cellular energy production, muscle physiology, brain health, recovery, and how creatine supplementation affects the body.
If you’ve received conflicting information about creatine, heard concerns about kidney damage or weight gain, or wondered whether creatine is actually healthy, this episode will help you understand what creatine does physiologically and how it works inside the body.
Many people don’t realize that creatine is not just a muscle supplement.
Creatine supports cellular energy systems used throughout the body, including:
muscle tissue
the brain and nervous system
recovery systems
cognition and mental fatigue
hydration and cellular function
In this episode, we explain the anatomy and physiology behind creatine, how the phosphocreatine energy system works, what creatine does inside muscle and brain tissue, and the research behind common myths and misconceptions.
If you’re looking to improve your understanding of energy production, recovery, muscle health, cognition, or supplementation, this episode gives you a science-based and approachable place to start.
