It allegedly is more easily absorbed through cell walls. Ferrous sulfate is the most common & cheapest iron supplement but may not be well tolerated.

How many 25 mg iron bisglycinate capsules should be taken to equal 325 mg ferrous sulfate?

Some studies show half the amount equals the ferrous sulfate so 175 mg of iron bisglycinate could do the same as 325mg of ferrous sulfate. However both will help iron deficiency. This not proven standard. Hope help ...Read more

CBC was ok. Day later drew a "full iron panel" (what's that & why check?) & said my iron levels were very low & put me on ferrous sulfate 325 mg.

However, some cases may still show numbers in the normal range, but tending towards a pattern consistent with iron deficiency. If the iron, iron binding and serum ferritin (panel) all point to deficiency then treatment is good. But should also ask why iron is low. ...Read more
