I just started with it and have had zero stomach issues so far, it will change your stool color slightly, but no pain or issues.
I've been using Thorne's bisglycinate iron for 3 months and I've noticed less bruising and less hair shedding.
This one seems to be easier on my body/digestion somehow than the other iron supplements I tried.
I have been having stomach pain, gas, slight nausea, and somehow constipation + diarrhea at the same time.
