Beta-glucans offer immune support, helping the gut recover quickly after digestive upset.

The Active Ingredient Is: Enterococcus faecium (DSM 10663/NCIMB 10415)

This formula also has included Prebiotics, kaolin and montmorillonite, pectin, psyllium and beta-glucans, which help support the primary role of the probiotic in maintaining a stable gut environment.

What Does Enterococcus faecium Do?
