What is the difference between the folate in OBTREX TRU versus any random prenatal you can get at a retail/drug store?

When taking a prenatal vitamin, the most important ingredient is folic acid. There have been some recent concerns that people with MTHFR polymorphism (variant) have trouble absorbing folic acid and may have an easier time absorbing folate in the form of a methylfolate supplement.

The patented and branded folate found in OBTREX TRU is called Metafolin (L-Methylfolate).  It provides 100% absorption regardless of whether a patient has this variant or not.  

Besides neural tube defects, there's evidence that folic acid supplementation may prevent other types of birth defects, as well as miscarriage, according to the Office on Women's Health.

It also protects pregnant women from developing folate-deficiency anemia, a condition that prevents your body from working properly, and in some cases can lead to problems with your baby's brain or spinal cord.
