Creatine beyond muscle: brain energy and healthy aging
Huberman's brain nutrient and muscle episodes and Kyle Gillett recommend creatine as one of the best-supported supplements, with benefits for both muscle and cognition. It's cheap, safe for most people and useful well past athletic years.
What two fronts does creatine work on, according to these conversations? Show answer
Muscle strength and power, and brain function, because neurons can use creatine as a fuel source.
What daily dose do all three conversations support? Show answer
About 5 grams of creatine monohydrate a day.
How does Huberman adjust the dose for body weight? Show answer
About 5 grams at roughly 180 pounds, 10 to 15 grams at 220 to 230 pounds, and 1 to 5 grams for lighter people.
Is a loading phase needed? Show answer
No. Taking 20 to 30 grams a day before cutting back appears unnecessary; a steady daily dose is enough.
What performance gains does Huberman cite for creatine? Show answer
Power output gains of roughly 12 to 20 percent in sprinting, jumping and lifting, plus reduced fatigue.
Who shows the clearest cognitive benefit from creatine? Show answer
People who eat no meat or other creatine-rich foods, whose baseline creatine is lower.
How strong is the evidence that creatine helps mood? Show answer
Huberman calls it an emerging literature that is still not well established.
What side effects do the sources name? Show answer
Some water retention, and possible hair loss in men sensitive to DHT, since creatine may raise DHT.
What is Kyle Gillett's view on creatine and hair loss? Show answer
Hair loss is not a reason to avoid creatine, because it restores a normal testosterone balance and does not push androgens above normal.
What does Gillett suggest for people who do not respond to creatine? Show answer
Increase to 10 grams, or use betaine at 1 to 3 grams.
How does Gillett describe creatine's role in the cell? Show answer
As a backup fuel tank for mitochondria, holding backup ATP, while also helping amino acid synthesis and oxidative stress.
What caveat applies to the healthy-aging case for creatine? Show answer
None of the conversations cites a study in older adults; the case rests on mechanism and broader arguments about muscle and neurons.
