jmb replied to saaa-wheat<3's topic in Other Food Intolerance and Leaky Gut IssuesAlthough it is possible to manufacture, there is no corn based powdered cellulose produced in North America. It isn't viable from an economic point of view. Most of the powdered cellulose produced is wood based with a smaller percentage from cotton, bamboo or sugarcane residue (bagasse). Microcrystalline cellulose is simply powdered celllulose which has undergone a further acid hydrolysis step to remove the non-crystalline portions of the cellulose chains. This makes the product more dense, flow easier and compress better through the tableting machines used by most pharmaceutical companies. Regarding an allergy to cellulose I am curious, does the reaction occur when wearing cotton clothes or if a sore/cut is swabbed with a cotton ball (pure cellulose)?
