Our read is that creatine supplementation is well-supported for its broad health benefits beyond athletic performance, particularly for individuals who do not exclusively consume meat.
Creatine is a safe and useful supplement that can provide health benefits beyond athletic performance, and is recommended for individuals who do not exclusively eat meat, according to Peter Attia, Andrew Huberman, Bryan Johnson, Rhonda Patrick, and Paul Saladino.
It may support prefrontal cortical function, suppress anxiety, improve environmental context interpretation, and enhance cardiovascular health markers.
While generally safe, potential side effects include GI irritation or diarrhea, and it may theoretically increase hair loss by increasing dihydrotestosterone (DHT), though this is not a reason to avoid it.
Taking 10 grams of creatine daily is generally safe, with a gradual titration approach, starting with 3 grams daily and slowly increasing to 5 grams, then 9 grams, potentially improving tolerance, as noted by Rhonda Patrick. Consuming creatine with 80-100mg caffeine (a normal cup of coffee) or 160mg caffeine (two K-cups) should not cause significant interference, according to Rhonda Patrick and Paul Saladino. A loading phase of 20 grams per day is unnecessary; five grams daily saturates muscles in 3-4 weeks, as stated by Peter Attia and Bryan Johnson.
Creatine supplementation may theoretically increase hair loss by increasing dihydrotestosterone (DHT), but this is not a a reason to avoid creatine, according to Peter Attia, Andrew Huberman, Rhonda Patrick, and Paul Saladino. Combining creatine with high doses of caffeine (>250mg) may blunt creatine's effects, as noted by Rhonda Patrick and Paul Saladino. The standard recommendation of 5 grams of creatine monohydrate per day is not universally supported by scientific literature for all individuals, according to Andrew Huberman and Rhonda Patrick. In healthy individuals using reasonable doses, creatine does not cause kidney damage, as stated by Peter Attia, Rhonda Patrick, and Paul Saladino. Buffered creatine and creatine ethyl ester are unnecessary marketing ploys, according to Peter Attia and Andrew Huberman. Claims about creatine's cognitive benefits are premature as current data primarily comes from clinical populations, not from healthy individuals seeking a cognitive boost, as noted by Andrew Huberman and Rhonda Patrick. Creatine does not cause cramps or dehydration; it super-hydrates the muscle, according to Rhonda Patrick. Peter Attia and Bryan Johnson state that a creatine loading phase of 20 grams per day is unnecessary; five grams daily saturates muscles in 3-4 weeks. Peter Attia and Rhonda Patrick advise caution with multi-ingredient compounds where other ingredients may compromise creatine effectiveness. Paul Saladino notes that the paradigm that meat should be avoided for longevity is myopic and ignores benefits like creatine, and that creatine and vitamin B12 are essential nutrients not found in plants. He also states that shunning animal foods can lead to inadequate intake of essential nutrients uniquely found in them, such as creatine, carnitine, choline, carnosine, taurine, anserine, vitamin K2, vitamin B12, and specific peptides. Peter Attia, Andrew Huberman, and Rhonda Patrick state that creatine is not a hormonal substance and likely does not need to be cycled.
The benefit of creatine supplementation is questionable for individuals eating a carnivore diet or a large amount of meat, according to Paul Saladino. Higher doses of creatine might be needed for cognitive function, as noted by Peter Attia.
The effect size is large enough to matter clinically, not just statistically.
Mechanistic and trial evidence converge on a real, replicable effect.
Benefits hold across the populations where it's been tested.
