With pet owners paying more attention than ever to their cats' wellness, many have sought natural, health-boosting dietary supplements for their furry friends, and nutritional yeast is developing a following. Nutritional yeast was once best known as a vegetarian and vegan staple, beloved for its umami taste and impressive vitamin and mineral content, but it has recently emerged in the realm of pet nutrition. But how does this supplement benefit feline health?
What Is Nutritional Yeast?
Nutritional yeast, known as "nooch," is an inactive form of the yeast Saccharomyces cerevisiae. Nutritional yeast is different from baker's or brewer's yeast, which are alive when consumed: Nutritional yeast strains are grown solely for use as a food product, and they are not alive when you eat them. It usually arrives in flakes or powder form, and adds a cheesy, savory flavor.
The nutritional yeast is full of B-complex vitamins, protein, fiber, and trace minerals, being a powerful supplement for humans and animals. Fortified varieties may be fortified with extra B12, a vitamin that is not naturally produced in plant-based origins.
