Changed Creatine brand - experiencing drowsiness
tldr: Switched creatine source. Why is new creatine source causing immense drowsiness?
A couple of weeks ago I switched from Equate creatine monohydrate (Walmart brand) to Momentus creatine. My only motivating factor for the change was momentus’ nsf sport certification. After reading about baby formula recalls and chewables incorrect/inconsistent dosing, I figured there’s no way to just trust supplement companies at their word. I’m sure nsf/informed sport and other certs aren’t perfect in assuring quality control but better than nothing.
I didn’t expect there to be any change switching - creatine is creatine. But I was very wrong. My guess is Momentus finer powder/better manufactured it’s being absorbed into my system significantly faster - and that’s causing the sleepiness? If I don’t get moving soon after taking 5g in the morning I’ll be hit with intense drowsiness to the point I’ve had to take an hour+ long nap. On the flip side, taking 5g before bed has improved my sleep time and quality (something I’ve struggled with).
Is there any reason a change in sourcing would cause drowsiness/change the metabolic response? Has anyone else experienced this?
