Personally I have noticed a lot less cognitive impairment after a poor night’s sleep since starting on 10g per day. It seems to make a noticeable difference in my ability to reason and to act having slept less than 7 hours per night, even on consecutive nights.

And yet you soon get tired and slow down. Now try the opposite. Stretch or punch the air a few times to get the heart rate going. You'll sustain brain performance for longer. Try it.

Perhaps the problem is that higher brain activity SHOULD trigger heart rate increase, but doesn't due to one of many design defects of the human body.

Well, yes. It is well known that you must eat fish, beef, i.e., animal protein, to get close to optimal levels of creatine.

Dang, missed opportunity to explain the actin-myosine sliding filament theory.

I started taking 5g for cognition. Never any clear signal for that, but it does seem to help a bit with my (more than occasional) sleep deprivation. Mostly with fighting off headaches.

Its something you might aswell just take, no proven side negative side effects, unless you are gulping it, it will benefit you
