Q: Why do Wysong Pet Diets contain yeast?

A: Wysong Pet Diets and cat and dog supplements contain a nutritional yeast culture, also known as Saccharomyces cerevisiae. This is a living culture, not a dead extract such as brewer's yeast. Wysong yeast culture is used because it is a natural and extremely rich source of B-vitamins, as well as other naturally complexed nutrients. It is a probiotic that secretes beneficial digestive enzymes and enhances immunity. It is also a prebiotic with cell wall mannanoligosaccharides that encourage the growth of other probiotic microorganisms.

Q: Do you have any diets that do not contain yeast?

A: Yes, the Au Jus™ Canned Diets.
