Fortified nutritional yeast, containing 18 amino acids, is an excellent source of protein, fiber, and B-vitamins (including B-12), and it adds a cheesy, nutty flavor to a whole range of foods without adding loads of fat or sodium.

Use it as a condiment on rice, in stir-fries, on salads, garlic bread, tofu scrambles, and roasted potatoes; nutrition-charge your popcorn; add it to gravies and sauces (1/2 teaspoon per 1 cup liquid); add a teaspoon in each cup of flour or meal used in baked goods, make a yeast cheese for your vegan pizza or lasagna, use it in place of parmesan cheese, or add it to your cat or dog’s food “to help eliminate fleas and promote a healthy coat and good general nutrition” (“Yeast Meets West,” Sundance Natural Foods Online).

Take note that not all nutritional yeasts are fortified with B-12.
