The “Other Ingredients” in Histamine Block serve a variety of purposes, but collectively they serve to help the active ingredient flow into the capsule and make sure it is also stabilized. The cellulose polymers provide the structure of the capsule. The rice starch is used as a protective, inert carrier for the DAO. A research study from Penn State shows that corn starch produces protective pockets in its structure and allows heat- and acid-sensitive compounds to be carried through the digestive system intact. The shellac is used as a stabilizer due to its high stability against UV radiation. It is highly purified, food-grade, and natural. The crospovidone is included as a dispersal aid – it helps to make sure that the contents of the capsule disperse well in liquid for optimal absorption. The sodium carboxymethylcellulose is also used as a carrier for disintegration and dispersal. The magnesium silicate is an anti-caking agent used to protect the contents of the capsules from any moisture contamination. The glycerol is included as an emulsifier and stabilizer and helps to shuttle the DAO into cells. These ingredients are added by the manufacturer of the DAO used in this product - we hope to be able to work out a way to provide an effective Histamine Block product without many of these other ingredients at some point in the future. At this time, due to the exclusive patent held by the DAO manufacturer, further customization of the material is not possible.
Note: Titanium dioxide is no longer in the formula. This was used as a colorant for capsules to make them opaque. The capsules are now transparent.
