Is Iron Bisglycinate the Same as Elemental Iron? Understanding the Differences
When it comes to iron supplements, many people often encounter terms like “iron bisglycinate” and “elemental iron.” If you’re confused about these terms, you’re not alone. In this article, we will explore the differences between iron bisglycinate and elemental iron, helping you make informed decisions about your iron supplementation needs.
What is Elemental Iron?
Elemental iron refers to the actual amount of iron present in a supplement that is available for absorption by the body. It is the pure form of iron that the body needs to produce hemoglobin, the protein in red blood cells responsible for transporting oxygen. Elemental iron is often found in various forms in supplements, including ferrous sulfate, ferrous fumarate, and ferric citrate.
What is Iron Bisglycinate?
Iron bisglycinate is a chelated form of iron, meaning it is bound to two molecules of the amino acid glycine. This chelation enhances the stability and bioavailability of iron, making it easier for the body to absorb. Iron bisglycinate is often marketed as a gentler alternative to other forms of iron supplements, as it tends to cause fewer gastrointestinal side effects, such as constipation and nausea.
Key Differences Between Iron Bisglycinate and Elemental Iron
1. Composition:
– Elemental iron refers specifically to the iron content in a supplement, while iron bisglycinate is a compound that includes elemental iron bound to glycine.
2. Absorption:
– Iron bisglycinate is known for its superior absorption compared to many other forms of iron, including some that provide elemental iron. The chelation process helps iron bisglycinate bypass some of the common absorption barriers in the digestive tract.
3. Tolerance:
– Many users report that iron bisglycinate is easier on the stomach, causing fewer gastrointestinal issues than other iron supplements. This makes it a popular choice for individuals who have experienced discomfort with traditional iron supplements.
4. Dosage:
– When looking at a supplement’s label, it’s essential to note the elemental iron content. For example, a 30 mg dose of iron bisglycinate does not equate to 30 mg of elemental iron. Typically, iron bisglycinate contains around 20% elemental iron, meaning you would get approximately 6 mg of elemental iron from a 30 mg dose.
Choosing the Right Iron Supplement
When deciding between iron bisglycinate and other forms of elemental iron, consider the following factors:
– Your Iron Levels: If you have low iron levels or anemia, consult with a healthcare professional to determine the appropriate type and dosage of iron for your needs.
– Tolerance: If you have a sensitive stomach or have had adverse reactions to other iron supplements, iron bisglycinate may be a better option for you.
– Dietary Considerations: If you follow a vegetarian or vegan diet, you may need to supplement with iron to meet your nutritional needs. Iron bisglycinate can be a good choice due to its higher bioavailability.
Conclusion
In summary, while iron bisglycinate and elemental iron are related, they are not the same. Iron bisglycinate is a chelated form of iron that provides a more bioavailable and tolerable option for those requiring supplementation. Always consult with a healthcare provider to determine the best form of iron for your individual needs and health status. By understanding the differences between these terms, you can make better choices about your iron supplementation and overall health.
