<<Disclaimer: Verify this information before applying it to your situation.>> I just wanted to say that I was talking to the people at "Nature's Way" - they distribute herbs/vitamins/minerals. While I was only enquiring about a specific herb, they were very thorough in their reply to me (it was done over the phone) to the point that they would guarantee only certain strengths of the herb, as the fill in the other preparation included millet (sp?) and their research was not prepared to declare that ingredient as GF. They do not have a mail out for all their products' status, but welcomed calls @ 1-800-962-8873. They have a website, too, but it only lists the products.
