Can somebody weigh in on the quality of the study? Historically, Creatine research has reportedly been very biased.
The first study cited in the article, a meta study in cognition, alzheimer’s, sleep deprivation, traumatic brain injury, and depression notes:
DC has conducted industry-sponsored research involving creatine supplementation and received creatine donations for scientific studies and travel support and speaking honoraria for presentations involving creatine supplementation at scientific conferences and on social media. In addition, DC serves on the Scientific Advisory Board for Alzchem and Create (companies that manufacture creatine products) and as an expert witness/consultant in legal cases involving creatine supplementation. NF declares no conflicts of interest
There is no study. It's a review in a journal I have never heard of. The article references a review, a clinical trial ongoing, a podcast and a meta analysis paper.
Creatine is not really bioavailable and subject to a pile of bad research that claims it treats everything. When it doesn't work in real trials, they blame dose. Hundreds of papers from second and third rate sports nutrition labs all funded by supplements makers. Then, there are hundreds of meta analysis papers that summarize shit science and call it consensus. Jabroni science.
Any supplements that claim to treat >30 conditions are a red flag. But this is how you sell to brahs. No, I don't even lift.
The comments section on hacker news already has some rundowns, generally it looks low quality and then the reporting is taking unwarranted liberties on top of it. The supplement industry is desperate to get people to buy this dumb powder since it costs pennies to produce.
The funniest thing to me about the recent push to convince people to take it for their brain health is that they’re recommending 25+ grams a day for it, which is five times the standard recommendation. That’s the world we’re heading towards, paying $60 a month for your subscription to “higher cognitive functioning” based on studies that didn’t even have a placebo group lol
Which study are you referring to?
For additional information on the topic, interested individuals could peruse Examine.com's post on the topic (https://examine.com/supplements/creatine/?show_conditions=true) "Creatine is among the most well-studied and effective supplements for improving exercise performance. It does this mainly by increasing energy availability during high-intensity activity. Creatine may also provide cognitive and mental health benefits in some contexts."
You’re about 7 comments deep on this post and what, just refreshing to make sure you have the opportunity to correct the record with people who aren’t even replying to you?
Like I said I am referring to the HN discussion that was linked, go take it up with them if you’re in the mood to proselytize. Or go take it up with the many researches who have confirmed creatine’s borderline uselessness. There’s actually a post in my recent comment history w/ a meta analysis link if you want to go check it out. Do me a favor and make a top level comment somewhere else if you want to respond to it, based on your behavior in this thread I’m not interested in discussing it with you personally
Don'cha just love it when someone asks a small uncomplicated question? Could you be more specific regarding your question? Can you cite sources regarding creatine research being biased? In what directions?
The post above cites three articles and a podcast:

All im taking away from this is that nature will level the playing field for intelligence for meatheads late in life🤣 /s
:-D
A few things I can say, and am happy to have replies which expand or limit or clarify what I've said:
Generally speaking raising brain creatine phosphate levels comes secondary to raising muscle phosphocreatine. It has been suggested that daily 3-5g dose of creatine monohydrate will overtime, and with vigorous exercise upregulate creatine phosphate pathways in muscle, but is unlikely to raise phophocreatine levels and/or pathways inside the blood brain barrier. There appears to be no adverse effects to moderate supplementation on the kidneys in individuals without kidney (eGFR) disease. Hmm, what might one consider a moderate dose? 3-5g/d would be considered moderate amongst experts and informed individuals. Some experts might say taking 10-20g / d, in divided doses is currently considered moderate, and may be sufficient to raise phosphocreatine levels in the brain. Creatine tends to be low amongst vegans. Chicken eggs are relatively high in creatine.
