It depends on the insurance, yes. Mine covers it; so it's about $20. per month.

Some insurance companies do things differently. Some people cannot utilize folic acid because they lack the enzymes in the stomach to convert folic acid into folate which can cross the blood-brain barrier and make the vitamin available to increase serotonin production and that means, in my view, that it's an essential medication.

Because it's derived from a concentrated form of folate (Deplin, that is)
some companies won't insure it because it's considered a food rather
than a medicaton.

Go figure.
