Brief Summary

Ferrous sulfate is rapidly absorbed and the bolus of iron enters blood rather quickly possibly leading to higher concentrations of non-transferrin bound iron which induces oxidative stress. The objective of this study was to determine how quickly iron enters into blood stream from the iron-enriched Asperigillus oryzae (AspironTM, ASP) in contrast to ferrous sulfate. Seventeen healthy, female subjects (18-35 y) were randomized, double blind, cross-over experimental design with three treatments: 10 mg iron as FeSO4 and ASP as well as 20 mg iron as ASP.

Outcome Measures

Primary Outcomes (1)

  • Serum iron

    Area under the curve

    12 hours

Study Arms (3)

FeSO4

EXPERIMENTAL

Ferrou sulfate: Each participant was given a one time oral dose of the 10 mg iron as ferrous sulfate with the test meal (described in study design) and serum iron was measured every 30 min for 4 hours.

Dietary Supplement: Ferrous sulfate

ASP Fe (10 mg)

EXPERIMENTAL

ASP (10 mg Fe): Each participants was given a one time oral dose of ASP containing 10 mg iron. The capsule was consumed with the test meal and serum iron was measured every 30 min for 4 hours.

Dietary Supplement: Ferrous sulfate

ASP Fe (20 mg)

EXPERIMENTAL

ASP (20 mg Fe): Each participant was given a one time oral dose ASP containing of 20 mg iron The capsule was consumed with the test meal and serum iron was measured every 30 min for 4 hours.

Dietary Supplement: Ferrous sulfate

Interventions

Ferrous sulfateDIETARY_SUPPLEMENT

The intervention is the ASP, a natural form of iron supplement and compared to a widely used dietary iron supplement ferrous sulfate in terms of serum iron response over a 4h period.

Also known as: ASP (10 mg), ASP (20 mg)
ASP Fe (10 mg)ASP Fe (20 mg)FeSO4
