Certain naturally occurring elements on the face of the earth are extremely important for us to have in our bodies in regulated amounts. A bit of higher than desired levels or lower can cause major discomfort in our body.
Ferrous Sulfate and Ferrous Gluconate are two such elements that are imperative to have in our bodies in a certain quantity.
Key Takeaways
- Ferrous sulfate and ferrous gluconate are iron supplements for treating iron deficiency anemia.
- Ferrous sulfate contains a higher percentage of elemental iron, while ferrous gluconate has a lower concentration but may cause fewer gastrointestinal side effects.
- Both supplements require a prescription and should be taken as directed by a healthcare professional to ensure proper treatment.
Ferrous Sulfate vs Ferrous Gluconate
The difference between Ferrous Sulfate and Ferrous Gluconate is that while the former is more well receipted by our bodies in the sense that it gets absorbed in our blood-stream at a higher level, the latter does not mix well into our blood-stream, but both elements that are physically occurring forms of iron.

Ferrous Sulfate is the physically occurring form of the element Iron. It is derived from FeSO4, and its anions are inorganic. These compounds are small, and the bloodstream in our body does not absorb this element too well.
An interesting fact about it is that it exists in crystal-like types but is dependent on the water molecules that are attached to it.
Ferrous Gluconate is the physically occurring form of the element Iron. It comes from gluconic acid, and its anion is organic. These are much larger compounds.
Our blood-stream absorbs this mineral quite well and is certainly faster and better than Ferrous Sulfate. It is a great cure for anaemia and is also put to use as a food additive.
Comparison Table
Parameters of Comparison | Ferrous Sulfate | Ferrous Gluconate |
---|---|---|
Component | It happens to be an ionic compound | This is an ironic salt |
Weight of Iron | Much higher in comparison to its opponent | Significantly less in comparison |
Adaptability by Body | Quite poor | Remarkably good adaptability |
Mixing With Blood-Stream | It mixes slowly and not well with the blood-stream | The blood-stream absorbs it faster and better |
Purpose | Useful to preserve both human and plant health | Offers a great respite to those who have a low level of iron content in their blood |
What is Ferrous Sulfate?
It is an element that exists naturally, and its presence in our blood levels is of utmost importance. As has been discussed earlier, it is the naturally occurring physical form of the element Iron.
Iron is an element that exists in a limited number of physical forms that can be seen and utilized by man, and the above-mentioned component of iron happens to be one such form.
The digestive system of our bodies absorbs it, and it mixes well into our bloodstream, but the pace at which it mixes is a little slow. It is of utmost importance to maintain a proper level of this element in our body to avoid suffering from severe health consequences.
An important part of this iron compound is that the weight of iron in it is way higher than the weight of iron in ferrous gluconate.
Along with having a bit of difficulty in mixing into our bloodstream, this compound is also not too well received by our organs and can cause havoc on our body if taken in high amounts. Its prescribed dosage might take a while to show its effects, but one has to have the patience to wait for results.

What is Ferrous Gluconate?
This element, too, happens to exist naturally, and its presence in our blood levels is of utmost importance. As has been discussed earlier, it is the naturally occurring physical form of the element Iron.
Iron is an element that exists in a limited number of physical forms that can be seen and utilized by man, and the above-mentioned component of iron happens to be one such form.
The digestive system of our bodies absorbs it, and it mixes well into our bloodstream, but the pace at which it mixes is way faster in comparison to ferrous sulfate. It is of utmost importance to maintain a proper level of this element in our body to avoid suffering from severe health consequences.
It has to be mentioned that this ironic salt has a lower percentage of iron content in it in comparison to ferrous sulfate.
If someone has a low level of iron content in their blood, the consumption of ferrous gluconate could prove to be of substantial help. If a person has a low level of iron in their body, it will cause fatigue and tremendous weakness, and gradually, the symptoms can take a malevolent turn.
Therefore, one should consume ferrous gluconate to ensure that the bloodstream absorbs iron faster and better.
Main Differences Between Ferrous Sulfate and Ferrous Gluconate
- While Ferrous Sulfate is in ionic compound form, Ferrous Gluconate is in ironic salt form.
- The percentage of iron content in Ferrous Sulfate is in a dense concentration. On the other hand, the concentration of iron in Ferrous Gluconate is significantly less in comparison to Ferrous Sulfate.
- Our digestive organs absorb these elements into them to function better and enhance the overall performance of the body. Ferrous sulfate is not well-received by the organs in our body. In contrast, the organs absorb Ferrous Gluconate faster and better.
- Ferrous Sulfate does not mix well into our bloodstream. On the other hand, ferrous gluconate aids the blood in absorbing iron better and faster.
- The purpose that ferrous sulfate serves is that maintains good health in plants as well as in human beings, whereas the purpose that ferrous gluconate serves is that it offers a great respite to those who have a low level of iron content in their blood.
