This is the distinguishing feature that puts Natren at the top! Natren is a leading manufacturer of pharmaceutical grade quality probiotics. Why do we know this? By certifying your manufacturing processes where every step is checked to a recognised standard by a third party government agency. For NZ this independent auditing by a governmental agency is under the Australian Therapeutics Goods Agency. It gives International Pharmaceutical Good Manufacturing Practice certification called cGMP to Natren ensuring that the product has been tested for potency, purity, safety, strain identification and stability in all stages form the first culturing of the bacteria through to the expiration date. This recognition is only given to manufacturers that follow pharmaceutical standards in preparation and production of a product. Before a product can be released for sale, it must go through three rigorous quality control tests in- house and at independent labs. As pharmacists we understand the importance of a product having cGMP. Natren manufactures in their own state-of-the-art facility so that they can control the quality from start to finish.
