Supplementing with creatine (20 grams/day) improved cognitive function in Alzheimer’s patients by nearly 5% after just 8 weeks Patients experienced notable gains in memory, fluid cognition, inhibitory control, and attention (likely due to creatine’s key role in brain energy metabolism) Creatine seems to especially benefit the brain under stress...

Creatine is for Brain Power, not Just Muscle Power A New RCT just dropped looking at creatine hydrochloride (HCl) and creatine ethyl ester (CEE) on cognitive outcomes (PMID: 40854087). Researchers gave perimenopausal women 8 weeks of either low-dose creatine HCl (750 mg or 1.5 g / day), a blend of HCl + CEE, or placebo. 👉 The 1.5 g HCl group showed small but significant improvements in reaction time and even a ~16% increase in frontal brain creatine levels on MRS scans. The HCl + CEE combo didn’t outperform HCl alone. All forms were well-tolerated and there were no serious side effects. The results add to growing evidence that creatine supports cognition—not just strength, hypertrophy, and power—but let’s keep perspective: ⚠️ Creatine ethyl ester has consistently underperformed in bioavailability studies. Multiple head-to-head trials show it’s rapidly degraded to creatinine in the gut and fails to meaningfully raise muscle creatine compared to creatine monohydrate (PMID:19228401). Creatine HCl seems to dissolve better in water and some anecdotal reports claim it’s easier on digestion for some people, but so far there’s no solid evidence it improves muscle or brain creatine stores beyond what you get with monohydrate. Bottom line: this study is promising for the cognitive benefits of creatine overall, but it doesn’t change the main recommendation Creatine monohydrate is still the gold standard. It’s the form used in hundreds of human RCTs, proven to raise muscle and brain creatine, and it’s cheap. Until stronger data show otherwise, save your money and stick with monohydrate.

Rhonda Patrick just leveled up her creatine game—and the reasons will make you rethink that standard 5g scoop. She used to do 5g for workouts... now it's 10g EVERY DAY as baseline. Why? Brain saturation. "Once muscles are full at ~5g, the spillover hits the brain"—boosting cognitive function, potentially shielding against brain aging, and even helping depression via better energy production upstairs. Jet-lagged? Sleepless night? Travel wrecking your rhythm? She cranks to 15–20g (sometimes 20–30g in studies) — calls it "speed without the speed," like caffeine minus the crash/jitters. No addiction, but insanely alert, focused, and resilient. Hits hardest under stress/sleep deprivation (research backs it: single high doses reverse 21+ hour wakefulness cognitive hits and can outperform rested performance). Vegan twist: One friend (no meat = zero dietary creatine) went from dragging to "Bruce Banner → Hulk" mode after starting. Vegans/vegetarians often run low—liver makes only so much. Bonus layer: Extra creatine frees up methylation pathways (homocysteine → methionine), gene expression tweaks, brain-wide perks. 3:13 raw clip of Rhonda spilling the science—perfect if you're biohacking focus, longevity, or just surviving modern life chaos. Are you on creatine? Still at 5g? Gone higher for brain gains? Noticed Hulk-level energy when stressed/sleepless? Vegans—game-changer or nah? Drop your protocol/experience below—this one's sparking real convos!
