Low in iron - try supplementing with riboflavin (vitamin B2)

The body is incredibly complex with multiple interactions. That is why you should always take a multivitamin/mineral before taking just one nutrient.

It turns out that riboflavin is involved in iron absorption! So a study looked at supplementing riboflavin and its impact on iron status. The iron levels, as measured by blood hemoglobin, increased significantly. Yet iron intake did not change over the study period.  

The study gave women 2 or 4 mg of riboflavin a day over 8 weeks. Both groups saw the iron levels increase. Also of interest is the statement:
Moderate riboflavin deficiency is prevalent in certain population groups in affluent countries
So what this paper was saying is that we are not getting enough riboflavin in our diet. Yet another reason to take a supplement.

Also of interest is that they measured "erythrocyte glutathione reductase activation coefficient (EGRAC)" as a measure of riboflavin levels. I will do more research into this compound as I (a) don't know what this is and (b) unaware that there was a blood marker that indicated riboflavin status.
