The riboflavin-deficient women were randomly selected to receive one of three supplements daily for eight weeks:
Intake of iron did not change throughout the study.
Blood levels of riboflavin and hemoglobin, a marker of anemia, were measured at the start of the study and at 4, 8, and 12 weeks after supplementation began. The researchers found that:
This study suggests that even among healthy adults, low intake of riboflavin may be common. And for people who don’t get enough riboflavin, improving intake may help reduce the risk of iron deficiency, another common nutrition issue. Use our tips to ensure you are getting enough:
