Safety and Concerns. Nutritional yeast is the extracted contents from dead and deactivated species that cannot be used for leavening or fermenting and certainly cannot infect you. Yeast extracts do not contain any Candida species, which are the most common cause of pathogenic yeast infections in people.
I've never seen it in conventional grocery stores. Nutritional yeast is a yellow flaky substance with a strong smell. I keep a bag in the freezer and a jar in the fridge (I just refill from the bag). It takes me at least a month or two to go through a bag, and it never goes bad. While the cost per pound is kinda high, nutritional yeast is not very dense, so you will get a lot.
