                                According to the USDA, a standard 5-gram serving of nutritional yeast contains significant amounts of B vitamins, especially B12, making it a powerful vegan-friendly supplement. Determining exactly how much fortified nutritional yeast per day, however, requires understanding your individual dietary needs and the specific brand's vitamin content.
