Is folic acid found in a higher concentration fetus than mother?

Yes, folic acid is found in a higher concentration in the fetus than in the mother.

During pregnancy, the developing fetus has a high demand for folic acid, which is essential for the production of DNA, RNA, and proteins. The fetus obtains folic acid from the mother through the placenta, and the concentration of folic acid in the fetal blood is typically 2-3 times higher than that in the maternal blood. This is because the placenta acts as a selective barrier, allowing folic acid to pass through more easily than other substances.
