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)
You prove my point.
The moment a vitamin is proved by their own "medical" research to help a disease,
they scamper to term it a drug.
Neither niacin nor folic acid is a drug.
Both are members of the B-Complex group.
