Folic acid IS NOT your friend!​
Let's clear up some confusion: Folic acid IS NOT the same thing as folate and should NEVER be used as an equivalent. ​
Pregnancy health
Let’s Talk About Folic Acid!
Folic acid fortification was heavily implemented in 1998. Thank goodness it's 2019 and we now know better! The thing I love about science is it's ALWAYS evolving, it's constantly changing. If it wasn't, we would still be practicing bloodletting or performing lobotomies for mental illness. 
Folic acid is what we’re supposed to take while pregnant, right? WRONG! Folic acid is not the same thing as folate. If you are pregnant, please look on your prenatal bottle and make sure you are taking folate. 
Functional Medicine Folic Acid
Notice- Unmetabolized Folic Acid (UMFA): We don't know the full health ramifications, yet, but a lot of the evidence is pouring in, in a negative context. Notice- The importance of our B vitamin cofactors. Notice- Folate requires fewer steps than folic acid.
Folic Acid Vs. Folate:
  • Folic acid (pteroylmonoglutamate): is the man-made version of B9 found in supplements and fortified foods-
    • Requires multiple conversions by the body to achieve 5-MTHF status
    • Two of these steps involve dihydrofolate reductase (DHFR) which can easily become saturated at high folic acid dosages
    • Exists in the oxidized form and only has only one conjugated glutamate residue
    • Higher bioavailability than natural folates- readily absorbed across the intestines
    •  Folate receptor has a higher affinity for folic acid than for 5-MTHF
    • Theoretically this may impair transport of active folate through the body and across the blood-brain barrier
  • Folate: is the natural form of B9 found in leafy vegetables and legumes-
    • Requires fewer steps to achieve 5-MTHF
    • Is in the reduced form and is polyglutamated
What does this mean? Folic acid can inhibit transport of the necessary active folate across the blood-brain barrier where we need it to be able to support reductions in neuroinflammation.
Has your doctor suggested folic acid? ​Do you have questions on what prenatal you should be taking? Please, contact us today!
