Consumer Usage of Probiotics: 

Results of the 2022 CRN Consumer Survey on Dietary Supplements reveal that 16% of supplement users report taking probiotics, with some slight variation among age groups. Supplement users aged 35–54 are most likely to take probiotics, with 18% of adults in this age cohort reporting usage; followed by 16% of users aged 55+; and 15% of users aged 18–34. Historically, probiotics usage has skewed female and to adults aged 35–54.

Additional Tools and Resources:

  • CRN and IPA’s Best Practices for Probiotics: The Council for Responsible Nutrition (CRN) and the International Probiotics Association developed scientifically-based voluntary best practices  that address the labeling, stability testing, and storage recommendations for probiotic-containing dietary supplements and functional foods. These best practices are intended to facilitate transparency and consistency. 
  • Roadmap for Retailers: The Council for Responsible Nutrition created this guide to assist its members, their customers, and retailers selling dietary supplements with meeting their obligation under the law. As manufacturers and marketers of supplements are limited by law as to the claims they can make about their products on the labeling, in print or broadcast advertising, similar requirements and restrictions apply to retailers and distributors who speak directly with consumers. This guide supports individuals assisting consumers at the point of purchase to discuss dietary supplements accurately and legally.

About CRN's probiotics education campaign

CRN, at the direction of its Probiotics Working Group, developed an initiative to help educate retail buyers and other retail stakeholders on the intricacies of probiotic products. Understanding these intricacies will improve the chances of retail buyers purchasing high-quality probiotic products from responsible manufacturers. The initiative will also seek to educate retail dietitians, pharmacists, sales associates and other stakeholders on probiotics to help them better curate their offerings, improve their handling of these products, and educate their customers of the benefits of these products.
