Hi I was also very low iron and I get iron infusions every few months a series of five infusions 1 every week. for 30 minutes. then I get tested to see if it went up.
usually it goes up nicely but drops after a few months so I get another set of infusions.
the way to get started is to go to a hematologist who will do blood work and get you going.
you will feel much better after getting the infusions.
I figured that if they mix the iron with more saline its much easier on the stomach. (it takes a little longer.about 45 min.)
I would also recommend you to make juice out of romaine lettuce and spinach kale beets as they will help maintain the iron levels.
any other questions fell free to ask.
