Where folic acid is primarily absorbed?

We know that folic acid is a vitamin that belongs to B
complex vitamins. We also know that a the deficit of folic acid leads to megaloblastic
anemias.

First, the folic acid is absorbed in
gastrointestinal tract. To be more specific, folate is rapidly absorbed from
duodenum.

The absorption process is less rapid in the lower
small intestine region.

It is known that folate is not
absorbed in the large intestine.

After folic acid
absorption it occurs a hepatical conversion to tetrahydrofolic
acid.
