Creatine is a molecule your body makes every day, stored mostly in muscle, and it functions as a recharge system for your cells' main energy currency, ATP. The episode argues that creatine has been miscategorized as a bodybuilding supplement when it is actually a fundamental component of cellular energy production with documented benefits for strength, brain function, bone density, and mood—especially for women, vegetarians, and older adults.

What Creatine Actually Does in the Body

Your body does not run directly on food. It runs on adenosine triphosphate (ATP), a molecule that acts like a tiny rechargeable battery. When a cell does work—contracting a muscle, firing a neuron, pumping blood—ATP loses one phosphate and becomes ADP, a drained battery. The problem is that your body only stores a few seconds' worth of ATP at any moment. Creatine solves this by forming a reserve called phosphocreatine, which rapidly donates a phosphate back to ADP, recharging it into ATP. This system is especially important in high-demand tissues: skeletal muscle, the brain, and the heart.

Show Notes

Creatine has been treated like a bodybuilding supplement for decades, but research suggests it may also support brain energy, mood, bone strength, mitochondrial health, and healthy aging. In this episode, Dr. Josh Axe explains how creatine helps replenish ATP, why women and adults over 50 may benefit most, and how much to take for the best results. He also breaks down the research on strength, cognition, depression, menopause, and bone density while revealing the simple mistake that causes many people to give up on creatine before it has a chance to work.
