Common questions answered about Natural Cellular Defense Frequently Asked Questions
Who formulated NCD?
 
Dr. Harvey Kaufman, a biochemist from a small pharmaceutical company in Ohio, devoted 37 years of research to purifying and activating zeolite to formulate NCD. In 2001, he was granted a U.S. patent.
 
There are many different zeolites.  Which one is used in Natural Cellular Defense?
 
Clinoptilolite is the zeolite used in NCD.
 
How is the liquid zeolite in NCD different from powdered zeolite?
 
Powdered zeolite is still in its original mineral form. All minerals are in essence rocks and, for the most part, cannot be absorbed by the body unless changed to a water-soluble or liquid form. NCD's patented zeolite is in a water-soluble bio-available form.
 
According to biochemist Rik Deitsch, liquid, activated zeolite is nine to twenty times more active than powdered zeolite. The powdered form works well in the digestive tract and has been used for GI distress, but powdered zeolite molecules are far too large to be absorbed into the bloodstream, which limits the zeolite’s efficacy. Furthermore, powdered zeolite contains metals and other toxins that were drawn to it underground. These take up much of the available surface area of the zeolite, again limiting its efficacy. NCD’s patented activation process empties out the zeolite cage, removing any toxins and “activating” the molecule to be maximally effective.
 
How is it possible to purify zeolite? Wouldn’t the toxins that are freed from it be attracted right back into the zeolite after the chemical bonds are broken?
 
Our patented activation process empties out the zeolite cage and removes all extraneous metals, eliminating any toxins that were found with the zeolite.

The zeolite molecule is, for all practical purposes, indestructible. Temperatures of up to 900 F will not crack the molecule, and it can be frozen in solution and defrosted without any change in activity. It is also amphoteric, which means that it exists equally well in acidic or basic environments.
 
We heat powdered zeolite at temperatures approaching boiling point in a slightly acidic environment. We cannot break the molecule, but the heat in solution lengthens its bonds. In essence, we are “bending” the bars of the zeolite cage. The slightly acidic condition allows for easy cationic exchange and allows any absorbed material to “fall out” of the zeolite. This material precipitates out of solution and is removed from the product. The solution is then cooled slowly over 24 hours. What remains in solution are the micronized zeolite in molecular form and some lighter metals – calcium, sodium, magnesium, and phosphorus – which migrate back into the zeolite and help stabilize the molecule. When liquid zeolite is ingested, the lighter metals easily undergo cationic exchange with metals that have greater affinity with zeolite, particularly mercury, lead, cadmium, and arsenic.
