How Much Elemental Iron Is in Ferrous Bisglycinate?

Ferrous bisglycinate is a popular form of iron supplement known for its high bioavailability and gentle effects on the digestive system. One of the key considerations when choosing an iron supplement is its elemental iron content, as this determines the actual amount of absorbable iron per dose.

Elemental Iron in Ferrous Bisglycinate

Ferrous bisglycinate is a chelated form of iron, where iron is bound to two glycine molecules. This structure enhances absorption while reducing common side effects like constipation. The elemental iron content in ferrous bisglycinate is approximately 20% of its total weight.

For example:
– A 25 mg ferrous bisglycinate capsule contains about 5 mg of elemental iron.
– A 100 mg dose provides roughly 20 mg of elemental iron.

Why Does Elemental Iron Matter?

Since different iron compounds contain varying amounts of absorbable iron, understanding the elemental iron content helps in proper dosing. The recommended daily intake varies by age, gender, and health status, but most adults need 8-18 mg per day, with higher amounts for those with deficiencies.

Benefits of Ferrous Bisglycinate

– Higher Absorption: Better absorbed than ferrous sulfate with fewer side effects.
– Gentler on Stomach: Less likely to cause nausea or constipation.
– Lower Dosage Needed: Due to its high bioavailability, smaller doses can be effective.

Choosing the Right Supplement

When selecting a ferrous bisglycinate supplement, check the label for elemental iron per serving to ensure proper intake. Always consult a healthcare provider before starting supplementation, especially if you have underlying health conditions.

In summary, ferrous bisglycinate typically contains 20% elemental iron, making it an efficient and well-tolerated option for addressing iron deficiency.
