What it is

Nutritional yeast is a deactivated strain of *Saccharomyces cerevisiae*, a type of yeast. It is grown on molasses or beet sugar and then harvested, washed, and dried. The drying process deactivates the yeast, making it safe for consumption.

Why it's used

Manufacturers add nutritional yeast for its savory, cheesy, and nutty flavor profile, often used as a vegan cheese substitute. It is also a source of B vitamins and protein, making it a popular ingredient in plant-based foods, snacks, and seasonings.

Health notes

Nutritional yeast is generally recognized as safe (GRAS) by the FDA. It is a good source of B vitamins, which play a role in energy metabolism. JECFA has evaluated yeast and yeast extracts, and EFSA has also evaluated yeast and yeast products. No significant health concerns are associated with its consumption at typical dietary levels.

Allergen info

Nutritional yeast is not derived from any of the nine FDA major allergens. It is naturally gluten-free.
