Yes, the stuff used to make beer, bread, and kombucha, but with a different end-product. Nutritional yeast is a primary-grown yeast, which means it is cultivated specifically for its nutritional value and not as a by-product or a means to another recipe.
Binding our minerals to this nutritional yeast makes it the closest thing to a natural food-form, which means the body can fully and easily absorb as much of the nutrient as needed. Ingredients that don’t utilize the benefits of yeast simply won’t do the trick. And don’t just take our word for it – ask science.
