Provides Added Nutritional Content
The main reason for pet parents giving dogs a nutritional yeast product is for its protein and vitamin B content, says Dr. Lindsey Bullen, a board-certified veterinary nutritionist with Veterinary Specialty Hospital of the Carolinas. However, if a pet is on a commercial diet formulated to meet nutrient standards set forth by AAFCO , the pet should be receiving all essential nutrients needed to live and thrive, she says.
Nutritional yeast are often used for vitamin B deficiency in cases where nutrients arent being absorbed properly due to a gastrointestinal disorder, says Bullen. However, nutritional yeast supplements contain small amounts of each vitamin, necessitating large quantities of supplementation, she explains. Additionally, if the pet does have underlying GI disease, there are more effective ways to administer b-vitamins .
Additionally, experts say that because nutritional yeast is inactive, it doesnt have the same benefits of products containing live yeasts and is not considered a probiotic.
Can Dogs Eat Nutritional Yeast Is Nutritional Yeast Safe For Dogs
Can dogs eat nutritional yeast? Maybe youve had this thought while hearing people talk up the health benefits of adding nutritional yeast to various meals. If humans can eat nutritional yeast, can dogs safely eat it too?
The short answer is yes, dogs can eat nutritional yeast. But keep in mind that this is not the same kind of yeast you use in most recipes for bread or rising dough. That kind of yeast is quite dangerous for dogs, and they should never eat it.
There are quite a few health benefits that nutritional yeast can provide for a dog, and its also easy to serve up. Nutritional yeast can also help pep up the taste of your canines normal dog food!
As always, you must ask your regular vet before going ahead and sharing any human food with your resident canine, including nutritional yeast. Heres what you need to know about nutritional yeast and dogs.
Potential Toxicity If Given In High Doses
For example, some products contain garlic, says McFaddin. In low doses it can be safe for dogs, but in high doses can be toxic.
If taken in very high doses, nutritional yeast can cause flushing, feelings of being hot, and rapid breathing, says Romine. Theoretically, if it was fed as more than just a sprinkle/topper, it could add too much protein and/or phosphorus to the diet of a dog with chronic kidney disease.
Its important to note that nutritional yeast is not the same as bakers yeast, which Romine says is an important difference. While baking and brewers yeast are known to sometimes support bacteria that can lead to mycotoxin growth, nutritional yeasts typically dont have any more risk than other supplements.

Brewers Yeast Versus Nutritional Yeast
Both brewers yeast and nutritional yeast are made from a single-celled fungus Saccharomyces cerevisiae, more commonly known as yeast. The fungus is deactivated before they are used in food products, including pet food. This means that there is no truth to the assumption that consuming food or supplements that contain brewers yeast or nutritional yeast can cause the overgrowth of yeast in the body.
However, both brewers yeast and nutritional yeast have different nutritional profiles even though they are made from the same species. This is attributed to how each product is made.
Unlike brewers yeast, nutritional yeast is always primary grown, which means it is created specifically for the purpose of producing a dietary supplement.1

Is Nutritional Yeast Safe For Dogs
While nutritional yeast can provide vitamins, minerals, and antioxidants to supplement your dogs diet, there is a question of whether or not its safe for dogs to eat. We love our dogs, and the last thing that we would want to do is feed them a harmful ingredient.
The good news is that since nutritional yeast is inactive, it doesnt pose a risk for intestinal problems when fed to dogs. The same cant be said for active yeast, which can cause serious stomach upset when consumed.
That being said, nutritional yeast can cause health problems in dogs when consumed in large amounts. This leads us to the question: How much nutritional yeast for dogs is good?
The recommended amount of nutritional yeast to feed to your dog in a single meal is one teaspoon. To avoid any complications, you should never feed your dog more than one teaspoon of nutritional yeast at once, no matter the size of your dog.
You should also be wary of the possibility that your dog has a yeast allergy. For the first time you feed your dog nutritional yeast, you may want to consider starting with a portion lower than one teaspoon. If no problems arise, you can try feeding your dog one full teaspoon of nutritional yeast.
What Is Brewers Yeast
Brewers yeast is traditionally a byproduct of the beer-making process but can also be primarily grown. Both brewers yeast and nutritional yeast can be cultivated on sugarcane or beet molasses. Unlike yeast used for baking bread, these forms of yeast are deactivated and safe for your pet to consume.

Some people choose to add brewers yeast supplements to their dogs diet, but keep in mind that supplementation is generally not necessary if you feed a complete and balanced dog food formula.
As always, when youre considering making a change to your dogs diet, be sure to do your homework, explore all of your options, and talk to your veterinarian. Its the best way to find a formula that not only meets his nutritional needs, but also provides a taste your dog will love.
Nutritional Yeast Vs Other Yeasts

Nutritional B12 Tasty Yeast Nooch For Your Pooch
Dried inactive yeast is an essential component of a human vegan diet. It is called nooch and it is extremely rich in B vitamins, folic acid, zinc and B12 and it is very tasty dogs that normally love to eat cheese will love nooch as it has a cheesy flavour.
How is dried yeast made?
Yeast flakes are a natural food grown on molasses under carefully controlled conditions. The yeast we add to our protein packs for our Umameo treats, is a primary inactive yeast of the genus Saccharomyces cerevisiae, and it is entirely free from Candida albicans yeast . There is also the lower quality brewers yeast that is a by-product of the brewing industry .
Rather choose the highly palatable human-grade nutritional yeast for your dogs even better if it is fortified with Vit B12, and ideal to add to treat recipes or just add to kale and roast for a delicious and extremely healthy treat.
What function does Vit B12 have in the body?
An average 15kg dog needs 9g of Vit B12 in their diet daily for adequate enzyme function. A lack of Vit B12 results in appetite loss, lack of white blood cells and anaemia with bone marrow changes.
Vegan humans almost certainly always lack Vit B12 in their diets. Theoretically, enough Cobalamin can be generated from gut bacteria in both us and in our dogs, but as vegans we are often deficient in it so it is better to keep eating the nooch!

Whats With Nutritional Yeast
Weve had a few owners write in asking whether nutritional yeast is related to the yeast found on dogs skin, and worried that if they feed it to their dog they could make yeast skin infections worse.
We realise we need to put this worry to bed once and for all! We got our vet founder Dr Lucy to answer this question to sort out any confusion that has arisen from the fact that both are called yeasts but in fact, as shell explain, they couldnt be more different!
So, is nutritional yeast the same as yeast found on the skin, and can eating it in the diet predispose to skin infections?
Over to Dr Lucy:
I can totally see where the worry and confusion comes from, obviously they are both called yeast but thankfully they are very different and the answer is very simple: nutritional yeast is completely different from the yeast on the skin, and it does not cause skin infections.
