The CNCA Difference

At CNCA, our manufacturing process includes extensive testing for maximum purity and optimal potency. Our quality standards are unparalleled in the nutritional supplement industry, going well beyond the requirements of other certification programs. We achieve the highest levels of quality by using independent analytical laboratories to extensively test raw materials and finished goods for purity, identity and potency.

Testing performed on CNCA raw materials and finished products far exceeds the requirements of FDA GMPs as well as those required by USP and NPA certification programs.

For example, CNCA raw materials are independently tested for toxins and contaminants that are not required under USP and NSF certification programs. Our potency and metals testing are up to one thousand times tighter, and our exhaustive chemicals and solvents testing greatly exceeds USP and NSF standards. Finally, unlike other national standards, we screen all our botanicals for a full range of aflatoxins, agrochemicals, and solvents (more than 135 individual tests).

Because of our vigilance to quality, CNCA products are recommended by some of the country’s leading medical practitioners every day. CNCA products are used in hospitals, pharmacies, and by thousands of people across the U.S. who demand nothing less than the highest quality nutritional supplements.

CNCA is trusted by cancer patients with compromised immune systems and their doctors. Doesn’t everyone deserve the same quality in their supplements? For more information about why quality is so important, please visit our page with the facts about nutritional supplement quality.

We go to these extraordinary lengths to ensure that our superior quality products are consistently ultra-pure– because, in our opinion, this testing must be done in order to protect the public health. Our commitment to superior quality may make CNCA products cost a little more than the “bargain basement” brands, but if you’re as serious about your health as we are, it’s simply the right thing to do.
