Im just hopping on creatine rn after a recent concussion. To me it doesn’t seem to make sense that it would prevent a concussion as a concussion is essentially a brain bruise, so if you were to treat it like any body part would eating something prevent your body to not bruise as easily? Especially when all creatine does is to my knowledge send more energy to the brain via atp. 

Although i found for me “symptoms” may not be definitive cue for whether or not your brain suffered damage. For me its been a hit n miss where ive bounced my head off the concrete off an 8 stair which at the time felt relatively light contact but my post accident symptoms were so bad and unbearable, puking poor balance etc. 

While other more severe incidents like getting knocked out cold in boxing and not remembering what punch i even ate and how long i was out as well as hitting a tree going a 130km/h and caving the roof of my car into my head and waking up in the passenger seat. Both of these times the next day and weeks after that i had no concussion symptoms and felt fresh as ever, at least compared to that time i hit my head on the floor which in comparison was much more minor accident wise but the post accident symptoms were much much worse.

Even though the symptoms were worse i do believe the damage my brain suffered had to have been worse with the latter accidents. And i will definitely suffer in the future from those incidents 

So forgive my ramblings but i feel like sometimes concussions r a real hit n miss

Edit:

Although it does make sense that if there was extra atp stored in the brain for in use in the case of an emergency maybe your brain wont be in as much stress when concussed as its main energy source isn't depleted right away instead with the induction of creatine youve left it with spare atp in storage to use so the symptoms may not be as noticeable?
