Well the first thing that runs through my mind is a scenario of someone seeing this and saying to their self, "ooooh magnesium will help me for this job interview Im about to go to, let me take a load of that stuff so I can be at my cognitive best!"

That could make for a rough day...

I think this is good advice in general to never start a new food, medication, supplement, etc. when you have something important to do.

Doesn't matter what I take or eat or don't eat before an interview, this happens to me every time. Not when I wake up, not when I'm showering or getting dressed, but right before I have to walk out the door. I'm amazed that I've ever even landed a job.
