Key Moments
Creatine monohydrate is the gold standard form -- other forms are marketing hype
Layne Norton recommends creatine monohydrate as the only evidence-backed form. He covers what form to use, whether to do a loading phase, and debunks claims about fancy creatine variants being superior.
"I get this all the time, what form of creatine should I use? There's a lot of different forms out there."
Creatine for brain health: a 30g acute dose improved memory in one study
While creatine's muscle benefits require weeks of saturation, a recent study showed a large acute 30g dose improved memory. Norton cautions against over-interpreting a single study but finds it very interesting.
"A recent study showed that I think it was a large 30 gram dose of creatine, acutely improved memory. So that's just one study. I don't want to get too gung ho because we know how I feel about single studies, but it's very interesting."
