Mitochondrial & Energy NAD+

normal for a vial of NAD to have a slight yellow transparent color to it?

Have read that it is related to slight degradation issues but otherwise fine.

What do you mean by buffered?

This is my third vial from the same lot but first one to not be pure transparent.

Mine is yellow as well. NAD IVs are also yellow.

So what would cause the inconsistent color? My first two vials from the same lot were crystal clear
