What makes Actisaf® different to other probiotics?

Shaped like a Malteser, the live yeast cells are located in the centre of the granule and surrounded by a protective coating of dead yeast cells. This outer layer ensures that the live cells survive the feed manufacturing processes and make it to the hindgut of the horse intact.

The specific strain of yeast used - from the species Saccharomyces cerevisiae - is a yeast that is also patented and unique to Phileo. The strain has been rigorously researched and carefully selected to ensure effectiveness, reliability and optimal results when added to your equines diet.


Backed by Science

The latest metagenomic technologies allow us to measure Actisaf® Sc47's effect on the microbiome. By sequencing the microbiota, we can see that the microbial population in the hindgut shifts and shows a growth in key fibrolytic species, which are responsible for breaking down fibre (Figures 1 & 2).
