<<Disclaimer: Verify this information before applying it to your situation.>> Hooray! I found a Sublingual vitamin supplement called Sublingual B Total manufactured and distributed by Pharmaceutical Laboratories, Inc., Arlington, TX 76006. They have a number where you can request more information: 1-800-338-4788. The product I got contained a base of distilled water, Sorbitol, Glycerine, Citrid Acid, Fruit Flavor, and Benzoic aid. It is guaranteed to be free of all fillers, binders, yeast or alcohol. The person I spoke with couldn't absolutely guarantee that it was gf, but my husband, who severely reacts to accidental gluten ingestion, has been taking it for over a week without any bad reactions at all. It comes as a liquid in a bottle with a dropper and contains 100% U.S. RDA for Vitamin C, B2, B3, and B6 with 16,666% of B12 (a normal injectable dose--there are no known toxic levels of B12) and 300% of B5. The method for taking it is to place one full dropper under your tongue, hold for 30 seconds and then swallow. Cyndee Burgess Elkhorn Realty P.O.
