Easy iron

I recently found out I was anemic so looked for a iron supplement and chose this one. I heard this type of Iron causes less stomach issues. These capsules are easy to swallow even though they are big. No aftertaste. I haven't experienced any stomach issues thus far. I also like there isn't extra ingredients in them.

good product for the price. my husband has not complained about an upset stomach after taking (1 a day). so that is a good sign. i shopped for an iron pill that had less stomach /gastrointestinal issues and good absorption. this seems to be the iron pill that works.
