<<Disclaimer: Verify this information before applying it to your situation.>> I take this supplement called Transfer Factor System 200. It is manufactured by Tomorrows Foods andsold by Pro Health. I asked both companies if they were aware of the gluten content of the supplement. I was told there is no gluten by the distributor/reseller but for some reason I didnt quite get the sense he understood cross-contamination, etc. Tomorrows Foods has been completely unhelpful. Tried emailing them and my email keeps getting sent back to me. The ingredients the distributor read to me were vitamin C (as calcium ascorbate), bovine colostrum fraction and microcrystalline cellulose, coenzyme Q (as ubiquinone) and GELATIN (that was the only suspect ingredient to me). The bottle says "contains no yeast, corn, soy, wheat, sugar, starch, salt, preservatives, or artificial colors" but says nothing of gluten specifically. Grrr. Any ideas? I'm going to keep calling Tomorrows Foods but so far theyve been unhelpful. *Support summarization of posts, reply to the SENDER not the CELIAC List*
