Flinders University study links high folic acid doses to pregnancy bleeding risks

A study conducted by Flinders University and its collaborators suggests that high doses of folic acid during early pregnancy may be linked to an increased risk of vaginal bleeding. The research, which analyzed data from over 2,400 first-time mothers in South Australia, found that women consuming 800 micrograms or more of folic acid daily had a higher probability of experiencing vaginal bleeding, particularly in pregnancies involving a male fetus.

Lead author Dr. Hongyan Wang emphasized that while folic acid remains essential for preventing neural tube defects and women should continue to follow medical recommendations, the findings highlight a need to better understand the effects of higher dosages. The study raises questions regarding supplementation levels in regions where food fortification with folic acid is mandatory.
