What is Nutritional Yeast?

Nutritional yeast, also known as savory yeast, is a deactivated type of yeast that can be used to add a nutty and cheesy flavor to dishes. It is sometimes grown on sugarcane or sugar beet molasses and is then harvested, washed, heated and dried.

Nutritional yeast is an excellent source of B-vitamins (such as B1, B2, B3 and B6) as well as folic acid, selenium and zinc. It also contains protein at about 4g per tablespoon making it an ideal option for vegetarians or vegans looking for a healthy source of protein. 

What Are The Health Benefits of Nutritional Yeast in Humans? 

In recent years, people have been interested in incorporating nutritional yeast into their diets. There are various benefits of nutritional yeast. For example, a recent study conducted by Szydłowska et al. demonstrated whether nutritional yeast was beneficial for children who are on a vegan diet. They state: 

“Introducing nutritional yeast into the diet of a child restricting animal products has measurable benefits. It reduces the risk of deficiencies such as deficiency of vitamin B12, zinc, protein and the following disease symptoms.” (Szydłowska et al., 2023).

The most notable health benefits of nutritional yeast are its high vitamin B content and its ability to help with digestion. Vitamin B is essential for maintaining healthy brain function and producing red blood cells. 

Amino acid food sources

Furthermore, nutritional yeast contains all nine essential amino acids that the body can’t produce itself or needs to get from food sources. These compounds are important for proper muscle growth as well as energy production. You can view a PDF of a comprehensive scientific review article detailing the necessity of amino acids here.

Nutritional yeast also helps with digestion by providing beneficial enzymes called proteases which help break down proteins in the gut into smaller components so they can be used more efficiently by the body.

It can also be used as a prebiotic which helps to increase the number of beneficial bacteria in the gut microbiome which has been linked to improved immune system functioning and better overall health. 

Aside from these benefits, nutritional yeast is also high in antioxidants which protect our cells from damage caused by free radicals and environmental toxins. The antioxidant activity of this yeast may even reduce inflammation in the body which has been linked to numerous chronic diseases like heart disease and diabetes. 

Additionally, some studies suggest that it may help reduce cholesterol levels when taken as a supplement or added to foods due to its high fiber content which binds with bile acids and increases their excretion from the body through stools. 

Finally, nutritional yeast has been found to have anti-cancer properties due its compound beta glucan which acts as an immune system stimulator. Research suggests that this compound stimulates white blood cells like macrophages and neutrophils which are responsible for destroying cancerous cells in our bodies before they can spread any further than necessary.

While all this may be good and well for humans, does this translate to canines? Let’s find out.

So, Is Nutritional Yeast Good For Dogs?

There are many common benefits of nutritional yeast in humans and dogs. You can read about the benefits of a healthy gut microbiome for dogs in this scientific review article.

Nutritional yeast offers a range of health benefits for dogs, as it is packed full of vitamins and minerals. High in B-complex vitamins, including thiamin, riboflavin, niacin, vitamin B6 and folate, nutritional yeast can help keep your dog’s coat healthy and shiny while supporting their energy metabolism.

It also contains essential fatty acids such as Omega 3 which helps support joint health. Additionally, nutritional yeast provides the amino acid tryptophan which is necessary for proper growth and development according to some studies. 

Moreover, this type of yeast may be beneficial when it comes to digestion due to its high fiber content. As dietary fiber can help reduce constipation and improve digestion in general, this makes nutritional yeast a great addition to your pet’s diet. 

What’s more, the presence of antioxidant minerals such as zinc, selenium and manganese means that nutritional yeast can also be beneficial to your puppy’s immune system, helping them fight off disease-causing agents more effectively. 

It also has antifungal properties which can fight off any fungal infections within the body making it an even better addition to your pet’s diet.

How Can Nutritional Yeast For Dogs Be Introduced To Their Diet? 

Nutritional yeast can be given to dogs as a supplement in their diets, but it must be done responsibly and with caution. It is important to purchase nutritional yeast designed specifically for pets, as the ones that are made for humans can contain additives or flavoring that may not be safe for animals. 

Nutritional yeast can also be introduced gradually into your dog’s diet and it should never replace other necessary dietary components, such as fresh meat and vegetables. Making your dog food by yourself is both rewarding and potentially healthier for your animal. If you would like to learn more about the benefits of homemade dog food, see our article here.

When introducing any new food into your pet’s diet, it is always recommended to do so with guidance from a professional veterinarian. 

When giving your dog nutritional yeast however dosage should always be closely monitored and kept within the recommended amount for their size and weight. Generally speaking when supplementing any new food item into your pet’s diet you should start by adding only small amounts at a time so that adverse reactions (such as vomiting or diarrhea) can be avoided. 

If introducing nutritional yeast causes any major changes in your dog’s behavior or appetite then you should consult a vet immediately in order to rule out any potential allergic reactions or negative side effects.

We hope we convinced you that nutritional yeast is good for dogs. Introducing nutritional yeast to their diet may have positive health benefits. However, as stated, please consult with your vet if you have any doubts, or if you notice any warning signs.
