<<Disclaimer: Verify this information before applying it to your situation.>> Hi, First, Thanks you to everyone who replied to my questions on abdominal pain and calcium. I had so many responses and will summarize in the near future so everyone can benefit. In the meantime I was wondering if anyone knew whether Golds Horseradish (with passover vinegar) is GF? I bought it as Im assuming that because it is OK for passover it is safe, but a friend made me nervous by suggesting the vinegar could be Matzoh derived. Is this likely? I would really like to eat it, but I get so ill from gluten ingestion that I would rather be safe than sorry! many Thanks Amanda Amanda Hayward-Lester Ph.D Mooseker Lab, Dept of Biology KBT 342 266 Whitney PO Box 208103, New Haven, CT 06520-8103 Phone (203) 432 3469 Fax (203) 432 6161 Email [log in to unmask]
