That should be obvious.
Folic acid is found in
beans and legumes
citrus fruits and juices
wheat bran and other whole grains
dark green leafy vegetables
liver
The last I heard none of the above are "drugs."
The medical Industry wants to take over anything that is admitted to help a disease.
The word "drug" in the headline is a red flag telling me they are in the process of attempting that.
I read a similar article years ago where they tried the same thing with niacin, another member of the B-Complex group which causes the blood to circulate faster and is good for people past a certain age.
That article on niacin tried to call it a "drug," which it is not.

I take three things by prescription.
Niaspan = niacin
Omacor = fish oil
Folic acid = folic acid (but you need a scrip to get it 1000 mg)
