<<Disclaimer: Verify this information before applying it to your situation.>> I contacted the Consumer Relations department of the Sundown Drug Company this morning to check the current GF status of their Glucosamine product OSTEO BIFLEX. There representative was cordial but adamant that the OSTEO BIFLEX product line was NOT GF. The COSAMIN DS product remains GF as of a last week, but I have not received a positive status back concerning the TWINLABS Glucosamine product line. I will re-post upon comfirmation of it's GF status. Tony in Kensington *Please provide references to back up claims of a product being GF or not GF*
