<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone know if a prescription strength Folic Acid 1mg supplement is GF? On the bottle it has "Watson Labs" in small letters under the prescription name - I'm assuming that is the manufacturer. Also wondering about the GF status of the Safeway Select vitamins - in particular, the multivitamin without iron, and the B-6 50mg supplement. Stefanie (Virginia, USA)
