Peter Attia MDScrutinizing supplements: creatine, fish oil, vitamin D, and more (AMA 69 Sneak Peek)

WHAT IT’S REALLY ABOUT
Peter Attia's Six-Question Framework for Judging Supplements, Applied to Creatine
- Peter Attia argues that consumers should not draw an ideological line between natural supplements and pharmaceuticals, and should instead run any molecule through the same analytical framework.
- He explains that his practice approaches a new patient's supplement list by mentally dumping everything out and asking what should be added back, since many patients cannot say why they take what they take.
- The framework asks about correcting deficiency versus supranormal levels, lifespan versus healthspan, trackable biomarkers, mechanism of action, and the balance of risk and reward, including product quality.
- Applying it to creatine, he describes a low-risk, modest-reward supplement that improves muscle power and hypertrophy by roughly 5 to 15 percent, with promising but earlier-stage evidence for cognition and possibly extra benefit for women.
- The sneak peek ends as the fish oil discussion begins, with the remaining case studies reserved for premium members.
IDEAS WORTH REMEMBERING
5 ideasNatural versus pharmaceutical is a false divide
Attia says the real difference is regulation, with supplements far less regulated, and notes that high-dose red yeast rice is effectively a modest dose of pravastatin. He wants patients to analyze any molecule with the same framework.
Start from a blank slate with supplements
His practice uses a mental model like the kidney's filtration: dump everything out, then ask what should be added back. Many patients started something because of Instagram or an old recommendation and don't know why.
Not every framework question needs a yes
Attia stresses that a supplement need not satisfy all questions, such as understanding the mechanism, if confidence on other dimensions is high enough to proceed.
Creatine is used for supranormal levels, not deficiency
Muscle stores are saturated at about three to five grams per day, so little is gained beyond that. The older loading phase of around twenty grams is no longer the typical approach.
Creatine's benefits center on short, intense efforts
Through the phosphocreatine system it supports power and hypertrophy, but a meta-analysis he cites found no endurance improvement in trained athletes. Cognitive benefits look promising but may require higher doses.
WORDS WORTH SAVING
5 quotesI just wanna make sure you as the consumer of this understand the difference.
— Peter Attia
I think it's just helpful for patients not to get ideologically wrapped up in the idea of over-the-counter supplement versus pharmaceutical agent, um, and instead to just analyze the, any molecule you put in your body through the framework we're gonna talk about today.
— Peter Attia
you dump everything out and then ask the question, what should be added back in?
— Peter Attia
whatever, um, amount of nefarious behavior exists over there, I think you're safe multiplying that by 10 or 100 to the, uh, to understand the magnitude by which that's happening in the supplement space.
— Peter Attia
I would put this in the low risk, modest reward, um, category.
