<<Disclaimer: Verify this information before applying it to your situation.>> I recently received a letter from AH Robins, manufacturer of Centrum, regarding my question about gluten in their tabs. They say, "Pending validation from our suppliers we cannot guarantee that Centrum is totally 'gluten free', but we can say that the product does not contain any starches or other products primarily derived from wheat protein." I guess this means that Centrum is "probably" or "might be" gluten free. I think all these manufacturers have the same attorney!
