Hello.
My feritin is 9.93
Iron 4.90
Hemoglobin 12.3

Im taking iron supplements 25mg daily ( infusion didn’t work because my veins is too problematic)
Well , im training in gym 5-6 times in a week, today i added weights to abductor and i felt so dizzy, also im tracking my bpm on my watch and it was high, i felt like I was passing out,
Maybe its simply because weight change and that i stand ul so quickly idk but im now scared lol.
Does this happened to you as well?
Any advise?
