Question

When you buy an iron supplement of 325mg why does it say 65mg also?what's the difference?

Answer 1

325 mg ferrous sulfate tablets, the usual salt in iron supplements, deliver 65 mg of elemental iron (subtracting the "sulfate" part).

Answer 2

What does the dosage say? Many products' front labeling is misleading.  If they are 65mg each, you will get the 325mg by taking 5 a day, which is CRAZY!!  Look at the dosage instructions carefully.  Consult your doctor if you're not sure.
