Is a lower dose of more bioavailable iron (18 mg ferrous bisglycinate) noninferior to 60 mg ferrous sulfate in increasing ferritin concentrations in Cambodian women? A randomized controlled noninferiority trial
Fischer JAJ, Pei LX, Goldfarb DM
Published in The Journal of Nutrition
Key Findings
Low-dose ferrous bisglycinate was less effective than ferrous sulfate at raising ferritin in a largely iron-replete population.
Conclusions
18 mg ferrous bisglycinate was not as effective as 60 mg ferrous sulfate.
Supplements Studied
Iron
Mineral
Ferrous bisglycinate (18-mg) was not as effective as ferrous sulfate (60-mg) in increasing ferritin concentrations and did not differentially influence biomarkers of gut health.
