Bluebonnet's Chelated Iron 27mg is the higher-dose option in this line, matching the amount typically recommended during pregnancy or for a more pronounced iron deficiency flagged by bloodwork. It's still a chelated form, so it's easier on digestion than standard ferrous sulfate. Iron needs vary a lot person to person — this is the dose to reach for with a doctor's guidance or a confirmed deficiency, not as a default starting point. Keep out of reach of children.
