Saccharomyces cerevisiae

Brewer’s yeast (inactive)

Gut, skin, and immune support

Brewer’s yeast (Saccharomyces cerevisiae) is a functional yeast ingredient naturally rich in nutrients and yeast-derived compounds such as beta-glucans, mannan-oligosaccharides, and fermentation metabolites. These components are studied for their role in supporting digestive health, immune function, and overall wellbeing in dogs.

In canine studies, Saccharomyces cerevisiae products have been shown to positively influence the gut microbiota, including increased beneficial bacteria such as Bifidobacterium, while also supporting immune markers and normal inflammatory balance.

Research in dogs also links Saccharomyces cerevisiae fermentation products to skin and coat support, including effects on skin sebum, antioxidant status, and immune responses. This makes brewer’s yeast especially relevant in formulations aimed at supporting gut health, skin resilience, and coat quality (Jouany et al., 2009; Davenport, 2023; Lin, 2019; Wilson, 2022).
