Can Babies Have Nutritional Yeast?


Nutritional yeast, with its cheesy, nutty flavor and impressive nutritional profile, has become a popular pantry staple for many.

But when it comes to feeding little ones, parents often have questions. Can babies have nutritional yeast?

Quick Answer

In general, yes, babies can have nutritional yeast in moderation once they’re established on solid foods, typically around 6 months old.

The Benefits of Nutritional Yeast for Babies

Nutritional yeast boasts an impressive nutritional profile, making it a potentially beneficial addition to a baby’s diet. Here are some key highlights:

1. Rich in B vitamins

Nooch is an excellent source of B vitamins, especially B12, B6, and folate, crucial for a baby’s brain development, nervous system function, and healthy red blood cell production.

2. Good source of protein and fiber

Nutritional yeast provides a small amount of plant-based protein and fiber, contributing to satiety and digestive health.

3. Fortified with minerals

Some brands of nutritional yeast are fortified with iron and zinc, essential minerals for growth and development, essential for babies who are vegetarian or vegan.

4. Adds a savory flavor

The cheesy, nutty taste of nooch can entice picky eaters and encourage babies to explore new flavors.

Potential Downsides and Precautions

While nutritional yeast can be a healthy addition, it’s important to be mindful of potential downsides and take precautions:

1. High fiber content

The high fiber content in nooch can cause gas and digestive discomfort in some babies, especially if they’re not used to high-fiber foods. Start with small amounts and gradually increase as tolerated.

2. Niacin flush

Nutritional yeast is high in niacin (vitamin B3), which can cause a temporary flushing of the skin, a feeling like warmth or tingling. This is harmless and usually goes away within a few hours.

B vitamins are particularly important for vegetarian and vegan babies, as they can be difficult to obtain from plant-based sources alone.

3. Fortified vs. unfortified

Choose unfortified nutritional yeast if your baby has an MTHFR genetic mutation that affects folic acid metabolism. Consult your pediatrician if you have concerns.

4. Potential Allergies

While rare, some babies might have allergies to yeast. Start with a tiny amount and watch for any allergic reactions.

Tips for Introducing Nutritional Yeast to Babies

Here are some tips for incorporating nutritional yeast into your baby’s diet:

1. Start small

Sprinkle a tiny amount (less than 1/4 teaspoon) on breastmilk, formula, mashed potatoes, avocado, or yogurt. Gradually increase the amount as tolerated.

2. Mix it in

Add nooch to homemade sauces, soups, purees, or baby oatmeal for a flavor boost.

3. Make it cheesy

Combine nutritional yeast with spices like turmeric and paprika to create a vegan “cheese” powder to sprinkle on popcorn or roasted vegetables (not for babies under 1-year-old).

4. Keep it simple

Focus on introducing new single foods first and wait a few days before adding nutritional yeast to avoid confusion about potential allergens.


Nutritional yeast can be a healthy and delicious addition to a baby’s diet once they’re established on solids.

However, starting with small amounts is important, watch for potential reactions, and consult your pediatrician if you have any concerns.
