1 month Post RNY blood work questions

I bought a bottle of Vitamin Code Raw Iron. It is a plant based Iron and non-constipating, it has 22g of iron. I just started taking this. My multi vitamin is Natures Way Women's Energy formula. It had 18mg Iron. I'm post menopausal, and my three month bloodwatk, ferritin levels were good. No blood work except for A1C at six months. I've upped my vitamins since last week due to my gum surgery, nicely recovering now.
