and one of the things that may be happening there some people think that at least part of that is you've depleted brain creatine with that first impact and then there's a greater effect of the second impact

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.

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?
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.
