Food supplements suffer from a lack of proper quality standards. Prof. De Simone suggests the creation of a label to guide users.
What differentiates a great wine from an ordinary wine? Of course, a history of terroir, grape variety, fermentation and recognized know-how which all translate into an exceptional flavor and a guarantee of quality.
You may wonder what is the connection with probiotics? Well, in the same way that there are 1000 anonymous Chardonnay wines produced in the four corners of the planet, there are today thousands of probiotic formulations on the market. Unfortunately, health professionals and end users are finding it very difficult to make head or tail in all these products. How can they identify a “grand cru”?
Too many formulations available today are detrimental to the good reputation of probiotics and I am sorry to see on the market so many probiotics that have no scientific studies. The efficacy and safety of a probiotic depends on the choice, identity, quality and proportion of the strains used, concentration, fermentation and freeze-drying processes. The probiotics are not equal in these aspects.
This is why I think it would be useful today to create a label, like a PDO (Protected Designation of Origin) to guarantee a reliable quality and to protect against counterfeits.
