How Much Elemental Iron Is in Ferrous Bisglycinate?

Ferrous bisglycinate is a highly bioavailable form of iron commonly used in supplements to treat or prevent iron deficiency. Unlike other iron compounds, it is gentle on the stomach and has better absorption rates. But how much elemental iron does ferrous bisglycinate actually contain?

Understanding Elemental Iron in Ferrous Bisglycinate

Elemental iron refers to the actual amount of absorbable iron in a supplement. In ferrous bisglycinate, the elemental iron content is approximately 20% of the total compound weight. This means:

– 100 mg of ferrous bisglycinate provides about 20 mg of elemental iron
– Higher absorption rates compared to ferrous sulfate or fumarate

Why Does Elemental Iron Content Matter?

When choosing an iron supplement, the elemental iron dosage is crucial for effectiveness. Many supplements list the total compound weight, not the absorbable iron amount. For example:

– A 325 mg ferrous sulfate tablet contains only 65 mg of elemental iron
– A 100 mg ferrous bisglycinate capsule provides 20 mg of elemental iron but absorbs better

Recommended Dosage

The Recommended Dietary Allowance (RDA) for iron varies:

– Men & Postmenopausal Women: 8 mg/day
– Women (19-50 years): 18 mg/day
– Pregnant Women: 27 mg/day

Since ferrous bisglycinate has high bioavailability, lower doses may be effective compared to other forms. Always consult a healthcare provider before starting supplementation.

Conclusion

Ferrous bisglycinate contains 20% elemental iron, making it an efficient and stomach-friendly option. Knowing the actual absorbable iron content helps in selecting the right dosage for optimal health benefits.
