NR gave me weird GI stuff at 1,000 mg, anyone else see that?

I started NR at 500 mg a day a while back because I wanted something boring and low drama. That was fine for me. When I pushed it to 1,000 mg, I started getting a weird queasy stomach and a kind of hollow feeling in the afternoon.

It was not dramatic, just annoying enough that I noticed it at school and kept reaching for crackers, which is ridiculous. Dropping back down made it go away pretty fast, so for me that looked dose related, though it could just be my gut being fussy. I have also seen people say they get flushing or loose stools with it, but I have not had the flushing part myself.

I am curious what others have seen with bloodwork on NR, if anything actually moved besides the usual noise. Did anyone here notice liver markers, lipids, or just nothing at all? I am trying to keep the safety lens on this stuff and not turn every supplement into a science fair project...
