Safety & Testing

At NOW® we believe that natural products are safer and more effective than products made with ingredients not found in nature.

To ensure the safety of our products, NOW performs more than 16,000 analyses and tests per month. We test each of our incoming raw materials and ingredients, in-process ingredients and finished products. We test to meet federal cGMP (current good manufacturing practice) standards. NOW tests ingredients for key attributes such as identity, purity, potency, and composition. Very few natural products manufacturers perform finished product testing in-house due to the exorbitant cost and investment required.

NOW is committed to using only natural and non-GMO ingredients in our foods. We believe that GMOs are not natural, and we support increased farming of non-GMO crops, and even a ban on GMO crops for human consumption and animal feed.

In addition, NOW does not allow the use of irradiated ingredients in any of our products. Food irradiation is a modern manufacturing method that uses specific levels of ionizing radiation to prevent spoilage and kill potential pathogens. This unnatural process irreparably damages DNA and cellular membranes and interrupts enzymatic pathways.

Studies on the safety of irradiation are inconclusive and NOW will not allow irradiated ingredients in any of our products. We use sophisticated analytical instrumentation to determine if an ingredient has been irradiated.

From sourcing to shipping, we take the safety of our products very seriously, and we test and test again to ensure the products we produce are products we’d give to our own families.
