Ferrous sulfate has 65mg elemental iron per 325 mg, dried ferrous sulfate has 50mg elemental iron per 160mg. The RDA percentage listed on the bottles 47.5mg ferrous sulfate is 264%, while 50mg of elemental iron from 160mg dried is listed as being 277% of RDA. This cannot possibly be correct.
Ferrous sulfate at 47.5mg only has 9.5mg elemental iron. How can it be virtually the same dosage as 50 mg of elemental iron from dried ferrous sulfate? Help!
Ferrous sulfate vs elemental iron from dried ferrous sulfate?

Ferrous sulphate 300mg = 60mg elemental iron
Ferrous sulphate dried 200mg = 65mg elemental iron
The recommended dose of elemental iron for iron-deficiency anaemia is 100mg to 200mg daily. ie. 1 of the above tablets 2 to three times a day
The RDA of elemental iron for females 19 to 50 years old is 18 mg Iron per day ie. 1/4 of a tablet daily.
The dose of Iron will depend on what you are taking it for.
Some iron tablets are marketed for RDA allowances (low dose iron supplements) and others for Iron deficiency anaemias (high dose) .
