Key Differences

In terms of their effectiveness, while both Ferrous Sulfate and Iron Glycinate aim to increase iron levels in the body, their tolerability can vary. Ferrous Sulfate, being a salt form, can sometimes cause side effects like stomach upset. Conversely, Iron Glycinate, with its chelated form, is often gentler on the stomach and less likely to cause constipation.

Ferrous Sulfate and Iron Glycinate are both supplements commonly used to address iron deficiencies in the body. Ferrous Sulfate is a salt of iron, often prescribed to treat conditions like iron-deficiency anemia. It is known for its ability to provide the necessary iron that the body might be lacking, helping to restore normal red blood cell function.

On the other hand, Iron Glycinate is an amino acid chelate form of iron. This means that the iron is bound to an amino acid, often making it more bioavailable, which means it can be better absorbed by the body. As a result, Iron Glycinate is often recommended for individuals who experience gastrointestinal side effects with other iron supplements.

Additionally, while Ferrous Sulfate has been a long-standing choice for treating iron-deficiency anemia, Iron Glycinate's increased bioavailability and reduced side effects make it an attractive alternative for many. It's essential to note that the choice between Ferrous Sulfate and Iron Glycinate should be based on individual needs, tolerability, and doctor recommendations.
