Creatine 101
Muscle + Brain Fuel
What Is Creatine?
Creatine is a naturally occurring compound made from amino acids (mainly in liver, kidneys).
It’s stored primarily in muscles (~95%) as phosphocreatine, and a smaller portion in the brain and other tissues.
It helps regenerate ATP (the cell’s “energy currency”) during short bursts of high-intensity activity.
Benefits
Muscle Benefits of Creatine
Increased strength & power: Studies consistently show creatine helps you lift heavier / more intense sets.
Greater muscle mass / lean tissue: When paired with resistance training, creatine supports hypertrophy.
Improved recovery: It may reduce muscle damage and speed repair.
Anti-catabolic effects: Helps preserve muscle in calorie deficits or during aging.
Dr. Gabrielle Lyon emphasizes that creatine is especially useful because women often have lower baseline creatine stores, so supplementation offers more “room to grow.”
Cognitive & Brain Benefits
Creatine’s effects aren’t just for muscle — here’s what the research (and thought leaders like Dr. Rhonda Patrick) point to:
Improved brain energy metabolism: Creatine supports mitochondrial & cellular energy production in neurons.
Cognition under stress or sleep loss:
• A single high dose (25–30 g) of creatine has reversed some cognitive deficits from ~21 hours of sleep deprivation.
• Chronic supplementation (10 g/day) can help boost brain creatine levels and protect cognitive function.Neuroprotection, aging, Alzheimer’s: In small pilot studies, creatine supplemented participants showed ~11% increase in brain creatine and modest gains in fluid cognition, working memory, attention.
Why higher doses matter for the brain:
Muscle saturates more readily at ~3–5 g daily, but creatine delivery to the brain faces a tougher barrier (blood-brain barrier). That’s why cognitively targeted protocols often use higher doses to “spillover” into the brain.
Dosage, Protocols & Timing
| Goal | Common Protocol | Notes |
|---|---|---|
| Muscle / performance | 3–5 g/day (maintenance) | No loading phase needed; increases take a few weeks |
| Faster muscle saturation | 20 g/day (split over 4 doses) for 5–7 days, then 3–5 g/day | Traditional loading protocol |
| Cognitive / brain support / sleep-deprivation | 10 g/day or single higher dose (e.g. 25–30 g) | Some evidence that larger dosing helps brain uptake |
Timing:
The “best time” is often just when you’ll remember — consistency is more important than exact timing.
Some studies show no strong difference between pre- vs. post-workout for muscle outcomes.
Women vs Men: Should They Take Creatine?
Women benefit too (and sometimes more):
Increased strength & power: Studies consistently show creatine helps you lift heavier / more intense sets.
Greater muscle mass / lean tissue: When paired with resistance training, creatine supports hypertrophy.
Improved recovery: It may reduce muscle damage and speed repair.
Anti-catabolic effects: Helps preserve muscle in calorie deficits or during aging.

Best Practices & Safety
Use creatine monohydrate — it’s the most researched and cost-effective form.
Stay well-hydrated — creatine pulls water into muscle cells.
Expect small weight gain (water + lean mass) initially — not fat.
GI upset possible if taking too much in one dose; split doses if needed.
If you have kidney disease or liver issues, check with a healthcare provider first.
