Today, we see an atmosphere of increased consumer uncertainty regarding the quality of dietary supplements. 

The cause? 
Recent events and media reports have highlighted negative practices—from the New York Attorney General’s misuse of testing methods to the tainting 

The effect? 
Companies feel an urgent need for better testing to ensure the quality and integrity of their brands.

Regarding regulatory review, the FDA has noted the need for testing. They are responding with an increased frequency of citations and warning letters to companies lacking sufficient testing standards. Our clients are stepping up efforts to solidify testing programs and stay ahead of the curve. All of these signals lead us to focus on the future of testing: 

Where are your most significant risks? How can you be better prepared?

Our webinar addresses Three Key Steps to being proactive about your testing and data practices:

  1. Focus on Identity of Raw Materials
  2. Focus on the Use of Scientifically Valid Methods
  3. Focus on Shelf Life and Expiration Dates – Plus Data to Support Your Claims

We could consider more aspects, but based on our experience with hundreds of companies, many have these three deficiencies in common. Bridging gaps in these vital areas can help prepare you for future inspections and regulatory audits.
