<<Disclaimer: Verify this information before applying it to your situation.>> Spoke with a friend of mine about GF vitamins. She's allergic to some wheat products and to beef. She has found that if a vitamin/capsule is listed as GF, that beef byproducts are used instead ... so she orders liquid vitamins to be on the safe side. Thought I'd toss this out in case anyone has specific details and/or a beef allergy ... tracey in connecticut day #11 GF and almost chipper
