Answer: 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.
