Bezwecken is committed to quality, effectiveness and service. 

Bezwecken is proud to meet and exceed the current Good Manufacturing Practices set forth by the FDA. We are routinely audited and utilize ISO certified third-party testing laboratories for our raw material, in-process and finished product testing. We make no compromise when it comes to quality as it is the reason our products continually provide consistent and effective results. 

Bezwecken is a privately-owned small company, located in Wilsonville, Oregon. We produce everything in-house: from manufacturing to packaging, and shipping to customer service. We are proud of our small size as it allows us to handle each step of producing quality products with exceptional care.


We believe distribution of our products within the context of the practitioner–patient relationship uniquely enhances the value of our products and the health and wellness goals of the patient. We hope you see the professional and competitive benefits that are available to you as a Practitioner Wholesaler.
