When can babies eat nutritional yeast?
Nutritional yeast is a deactivated yeast that comes in yellow flakes or powder, with a savory, cheesy, umami flavor. It is a favorite in vegetarian and vegan cooking because it adds a cheesy taste without dairy, and it is often fortified with vitamin B12. A small sprinkle can join your baby's food around 6 months as an easy flavor and nutrient boost. It is worth noting that this is not the same as active baking yeast or brewer's yeast.

Is nutritional yeast safe? Choking & prep
Nutritional yeast is easy to serve: just sprinkle a little over food for flavor and a B12 boost, with no cooking needed. A small amount goes a long way, so start with a light sprinkle. Importantly, nutritional yeast is not the same as active baking yeast or brewer's yeast. It is deactivated, meaning it will not rise or ferment, so it is safe to use straight from the container. Choose a fortified variety if you want the B12 benefit.
