14 May 2019 --- Could a global logo or seal to communicate the quality of probiotic products could be on the cards, following the publication of an expert opinion in Frontiers in Microbiology? The paper has set out recommendations for the probiotics industry to bring transparency to consumers about what their probiotic products contain. As well as products undergoing third-party evaluations, labels could communicate genus and species names, strain designations and quantities for all strains present, a use-by date, storage instructions and company contact information. As the probiotic market continues to proliferate, improving transparency – even in the absence of regulatory requirements to do so – is paramount, the researchers note.
