Nutritional yeast is a deactivated yeast, specifically Saccharomyces cerevisiae, the same species used in baking and brewing. This means it’s not a live yeast like the kind used in baking or brewing. It’s grown specifically for its nutritional value and savory flavor, rather than for leavening bread or fermenting beverages¹.

Nutritional yeast, often nicknamed “nooch,” has gained popularity as a vegan-friendly superfood due to its impressive nutritional profile. This golden-colored supplement is a complete protein, containing all nine essential amino acids that the body cannot produce on its own. What makes nutritional yeast particularly valuable is its exceptional B-vitamin content, especially vitamin B12, which is primarily found in animal products. Fortified nutritional yeast can provide more than 300% of the recommended daily amount of vitamin B12 in just one tablespoon, making it an essential supplement for vegans and vegetarians².

Beyond its protein and vitamin content, nutritional yeast contains beneficial compounds like beta-glucan, a type of fiber that may help lower cholesterol levels and support immune function. It also provides important minerals such as zinc, which aids in immune support and wound healing, and selenium, which acts as an antioxidant. The savory, cheese-like flavor makes it an excellent dairy-free alternative for adding umami taste to various dishes, from pasta to popcorn.
