The Best Practices Guide was developed and published jointly by the Council for Responsible Nutrition and the Enzyme Technical Association to help promote the safe production and use of enzyme-containing dietary supplements and to facilitate transparency and uniformity in the dietary supplement and enzyme industries.  The Best Practices Guide was prepared with input from the dietary supplement and enzyme industries and takes into account the current U.S. laws and government regulatory requirements.  It reflects the most up-to-date science and industry thinking with regard to the safe handling of enzyme-containing dietary supplements and will be updated as best practices evolve.
