Nutritional yeast is a type of yeast that is grown specifically to be used as a food product. It is commonly used as a seasoning or condiment, and is known for its savory, umami flavor. Nutritional yeast is also a popular ingredient in many plant-based diets, as it is a good source of protein and other important nutrients.
In protein powders, nutritional yeast may be added as a source of plant-based protein, as well as vitamins and minerals. Nutritional yeast is particularly rich in B vitamins, including thiamin, riboflavin, niacin, and vitamin B12 (when fortified), which are important for energy metabolism and overall health.
Nutritional yeast is generally considered safe for consumption and is widely used in many plant-based and vegan diets.
