There is only one ingredient, Noochy Licious is a premium strain of nutritional yeast cultured in the USA especially selected for it's flavour and protein profile.
Nutritional Yeast is a high protein single-celled organism, Saccharomyces Cerevisiae, which is grown on molasses and then harvested, washed, and dried with heat to kill or “deactivate” it.
Because it is completely inactive it cannot cause candida or any kind of yeast overgrowth.
Also, don’t worry; no animals are harmed in this process because yeasts are members of the fungi (mushroom) family and are not animals.
