where are you buying iron supplements

I am wondering what brand of iron supplements everyone is using.

Many use the iron patch from Patch MD. I have ordered them but haven't started them yet. I also take oral iron Proferrin.

I take Proferrin ES, which is heme iron, so it is more absorbable and has fewer side effects (e.g. constipation, nausea). I buy it from the company's Website or else you can purchase it on Amazon.
