Whatever the factors involved, flying while anemic is not a good idea.
You don't want to find out that you have the wrong combination of
factors by passing out at 5000 feet.

Are you going to be asymptomatic then magically pass out at 5k feet?
Hardly. And again, anemia is a matter of degrees. Normal hemoglobin
levels have a LOW normal value in the ballpark of 13-14 grams/dl. There
is a lower acceptable low value in women as opposed to men.

Why do you waste your time? g
I can say, as a woman with a level that is generally around 11-12g/dl, I
don't magically pass out at 5000 feet. I don't even magically pass out
around 10,000 feet. I can say that I prefer not to fly along at night
without oxygen above around 6000 feet, but like they say, the first
thing to go is vision....which comes back very rapidly at lower
altitudes. Daytime...I've done 11,000 with symptoms, and again,
wouldn't do it alone and without oxygen, but no passing out.

So.. how about YOU stick to what you know.. flying sims.. leave the real
flying to the real pilots.. and leave the medical stuff to the folks who
deal with it for a living?

Good luck with that.
