Pet food manufacturers serve increasingly diverse and demanding customers around the world. The variety of products continues to grow.

Research shows TruMune postbiotic maintains stool quality under normal and stress conditions.

Research shows TruMune postbiotic does not impact palatability.

Yes. TruMune postbiotic has an 18-month shelf life and is stable through extrusion and processing conditions normally found in pet food manufacturing.

No. These are two distinctly different ingredients. Yeast culture (AAFCO Definition 96.8) is a very nutritionally unique and complex pet supplement ingredient, containing both residual components of the original yeast cells as well as a myriad of bioactive metabolites the yeast produces during the controlled fermentation process employed for its production. Conversely, brewer’s dried yeast (AAFCO Definition 96.4) is a by-product from the brewing industry wholly comprised of spent yeast cells. While generally a good source of protein, it lacks the myriad of fermentation metabolites intentionally derived in the production of yeast culture.
