The Claim
In pregnant women in Tanzania, the preference for a daily multiple micronutrient supplement containing 30 mg of iron is not greater than for 45 mg or 60 mg doses when preference is measured after direct exposure to all three formulations.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among pregnant women in Tanzania, preference for a daily supplement with 30 mg of iron is no higher than for supplements with 45 mg or 60 mg of iron when women have experienced all three options.
See the scientific wording
In pregnant women in Tanzania, the preference for a daily multiple micronutrient supplement containing 30 mg of iron is likely no greater than for 45 mg or 60 mg doses, as measured by direct comparison after exposure to all three formulations, indicating that lower iron dose does not consistently improve preference.
When pregnant women take iron supplements, the iron irritates the stomach and intestines, causing nausea, vomiting, or stomach pain. These physical discomforts make them less likely to want to keep taking the pill, no matter how much iron it contains. The more iron in the pill, the worse the discomfort, so women do not prefer the higher-dose pills even if they have more iron.
What the research says
1 studyThis study lets pregnant women in Tanzania try three different prenatal pills with different amounts of iron and then asks which one they like best. The claim says most women won’t prefer the pill with the least iron — and this study is set up to find out if that’s true.
