The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
creatine's ability to communicate with the calcium in the ATP system was the motivation behind the study that is the authors hypothesize on the basis of pre-clinical data in animals that by increasing creatine stores within the brain not just in the muscle but in particular within the brain that the availability of creatine would allow for better cognitive function in general
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
I've been recommending this to patients for 6 months now. The big shift is patients actually do it because the explanation is concrete.
Same in nutrition counseling. The before/after framing helps.
Tracking with a CGM on top of this for 3 months. Variability dropped quickly and stayed dropped.
Worth noting the 0.71 SMD in the Kreider meta is in trained athletes. Effect in untrained adults runs closer to 0.3 — still meaningful, but the panel should reflect that gradient.
Good catch. Could the brief surface the training-status interaction inline?
And there's some evidence that may be helpful for that as well. There's been some studies with children looking at creatine supplementation after um a TBI and it seems to help with their their recovery.
5 g of creatine monohydrate daily improves muscle strength and lean mass in healthy adults at standard training loads.
Creatine improves cognitive performance, especially under sleep deprivation and high cognitive load.
Creatine improves cardiovascular health markers and reduces all-cause mortality risk.
Creatine supports bone-mineral density in post-menopausal women when paired with resistance training.
Women need higher creatine doses (8–10 g/day) than men to reach the same intramuscular saturation.
