How Much Iron is Absorbed from Iron Bisglycinate?

When it comes to iron supplements, not all forms of iron are created equal. One of the most popular and well-researched forms is iron bisglycinate. But how much iron is actually absorbed from iron bisglycinate? In this article, we’ll explore the absorption rates, benefits, and considerations of using iron bisglycinate as a dietary supplement.

What is Iron Bisglycinate?

Iron bisglycinate is a chelated form of iron, where iron is bound to two molecules of the amino acid glycine. This chelation enhances the stability and solubility of iron, making it easier for the body to absorb compared to other forms of iron, such as ferrous sulfate.

Absorption Rates of Iron Bisglycinate

Research has shown that iron bisglycinate has superior absorption rates compared to non-chelated iron supplements. Studies indicate that the absorption rate of iron from iron bisglycinate can be as high as 80-90%. This is significantly higher than traditional iron supplements, which often have absorption rates ranging from 10-30%.

Factors Influencing Absorption

1. Bioavailability: The chelation process improves the bioavailability of iron, allowing for more efficient uptake in the intestines.

2. Dietary Factors: The presence of certain foods can either enhance or inhibit iron absorption. For instance, vitamin C can improve iron absorption, while calcium and tannins (found in tea and coffee) can hinder it.

3. Individual Differences: Each person’s digestive system is unique, and factors such as gut health, age, and existing iron levels can impact how much iron is absorbed.

Benefits of Iron Bisglycinate

– Gentle on the Stomach: One of the primary advantages of iron bisglycinate is that it is less likely to cause gastrointestinal discomfort, a common side effect of other iron supplements.

– Improved Tolerance: Due to its gentle nature, many individuals can tolerate higher doses of iron bisglycinate without experiencing constipation or nausea.

– Supports Overall Health: Adequate iron levels are crucial for energy production, immune function, and overall vitality. Iron bisglycinate can be an effective way to support these functions, especially for those with iron deficiency or increased iron needs.

How to Take Iron Bisglycinate

For optimal absorption, it’s recommended to take iron bisglycinate on an empty stomach. However, if gastrointestinal discomfort occurs, it can be taken with a small amount of food. Always consult with a healthcare professional before starting any new supplement regimen to determine the appropriate dosage for your individual needs.

Conclusion

Iron bisglycinate is a highly absorbable form of iron that can significantly improve iron levels in those who are deficient or at risk. With absorption rates of 80-90%, it stands out as a superior option compared to other iron supplements. If you’re looking to boost your iron intake, consider discussing iron bisglycinate with your healthcare provider for personalized advice and recommendations.

By understanding how much iron is absorbed from iron bisglycinate and its benefits, you can make informed decisions about your health and nutrition.
