Ferrous fumarate is an organic iron, which is absorbed better than ferrous sulphate, an in-organic iron. Ferrous sulphate may cause intestinal side effects, such as constipation, nausea, bloating...in many users, so it is produced in enteric-coated form, which may not absorbed as well as standard supplement. Ferrous fumarate is readily absorbed and less likely to cause intestinal side effects.
The main difference between ferrous fumarate and ferrous sulfate is the type of iron salt they contain. Ferrous fumarate contains ferrous iron bound to fumaric acid, while ferrous sulfate contains ferrous iron bound to sulfuric acid. Ferrous fumarate is often considered to have better absorption and fewer gastrointestinal side effects compared to ferrous sulfate.
Ferrous sulfate is cost-effective but can cause more gastrointestinal side effects compared to ferrous fumarate and ferrous gluconate. Ferrous fumarate has a higher elemental iron content, making it more bioavailable, but it may cause less gastrointestinal irritation. Ferrous gluconate is well-tolerated but has a lower elemental iron content, requiring higher doses for the same effect as ferrous sulfate or fumarate.
Thirty three percent of a ferrous fumarate is retained in the form of elemental iron, so for a 90 mg dose, we'd take 33% of 90mg which equals 29.7mg of elemental iron.
Ferrous gluconate provides 12% elemental iron. For example if you take 100 mg ferrous gluconate you will get 12% elemental iron. Similarly Ferrous sulphate provides 20% elemental iron and Ferrous Fumarate provides 33% elemental iron that is why ferrous fumarate is best supplement for iron deficiency specially in pregnancy and lactation.

The chemical formula for ferrous sulfate is FeSO4.

Ferrous ascorbate and ferrous fumarate are for different purposes. Ferrous fumarate is for the anemic patients those are deficient in iron while ferrous ascorbate helps retardation or prevention of Fe(II) oxidation.

Ferrous fumarate tablets typically appear as dark green or dark brown in color.
Ferrous sulphate, or iron (II) sulphate has the formula FeSO4.

There are various ferrous salts which can be given during pregnancy such as ferrous ascorbate, ferrous sulphate, ferrous fumarate, ferrous gluconate, etc. Various salts will have different proportion of elemental iron being absorbed in the body. It depends on inter-subject variability. Choice has to be made based on requirement of iron as well as better absorption of iron with minial side effects. Some patients do not have any issues with sulphate, fumarate salts whereas some may have - so the form of Iron is tailored at the beginning of treatment by gynecologist. Finally, answering to the above question, Ferrous ascorbate has better absorption profile with less side effects (though elemental iron supplied to the body is comparatively less). Hope it helps :) :)
Ferrous sulfate and ferrous gluconate are both forms of iron supplements used to treat iron deficiency anemia. The main difference lies in their chemical composition - ferrous sulfate has a higher elemental iron content than ferrous gluconate. This means that ferrous sulfate may cause more gastrointestinal side effects compared to ferrous gluconate.
