Alflorex® Dual Action 
Cultures - 35624® + 1714 Serenitas®

Mixing bacterial strains together can mean their individual properties are effected and they may even knock each other out. Therefore, for multiple strain formulations, it is important to assess the compatibility of the strains to ensure they have a synergistic rather than an antagonistic effect.

The clinical data for multiple strain formulations should be for the specified combination and not extrapolated from that of the individual strains.

A clinical trial confirmed the combination of the 35624® and 1714-serenitas® strains were synergistic.
These strains are contained in Alflorex® Dual Action.
