Brewers yeast is made from a one-celled fungus used to make beer and bread for centuries. It’s called Saccharomyces cerevisiae, a rich source of minerals, particularly selenium, chromium and B-complex vitamins. In addition to its uses in baking and brewing, it has also been used as a human health supplement for many years. Now brewers yeast for dogs is creeping into more and more commercial pet foods. So just what is the fuss all about?
So exactly what is brewers yeast?
A micro-fungus rich in protein, fibre, vitamins and minerals, brewers yeast has for centuries been used in wine making, baking and brewing. Today it is also a much valued nutritional and dietary supplemen. For both dogs and human beings. Read on to learn why brewers yeast is good for dogs.
I’m not for one moment recommending brewers yeast so you can start brewing beer for your dog by the way. Perish the thought. No, here we’re purely interested in the fungi’s canine health benefits. Honest!
That having been said of course, it has been done. Yes, today, you can actually buy non-carbonated, alcohol and hop-free beer for your best friend. Hooch for pooches. Grog for dogs. Call it what you will. I know my dogs would prefer a glass of their normal chicken bone broth, head or no head!
The many benefits of brewers yeast for dogs
Brewers yeast is a good source of vitamins B1, B2, B3, B5, B6, B7 and B9 (folic acid). As well as having a flavour most dogs enjoy, it is also a good source of chromium and selenium, of protein, energy and of essential fatty acids.
So just how does brewers yeast benefit dogs?
- Brewers yeast can help improve your dog’s skin and coat condition. It’s particularly good for dry, itchy skin.
- It may also help any dog which suffers from anxiety problems because of its richness in B-complex vitamins.
- And can help boost a dog’s immune system and promote healthy liver function.
- It can also help support good digestive health because of its high fibre content.
- And it can help maintain a dog’s blood sugar levels because of its rich chromium content.
Oh, and it’s also considered a natural tick and flea repellent. Not bad eh!
As you may have gathered, brewers yeast for dogs has rather a lot going for it. It’s definitely of those must-haves for the homemade dog food pantry!

Hi Gerald,
I have an 18 week old female Border Collie, and have added Brewer’s yeast to her evening meals. Is there a difference between food-grade human brewer’s yeast and that sold for canines? I’m prone to think there is no difference, but the cost.
Thank you.
Hi Pat, I would love to know this too. I suspect you are right. I give Brewers Yeast to my chicken too. And have simply bought a large bag from a health food supplier….they are thriving so I am going to add to my dogs evening meal as well…I have two male border collies, both at 11 months old. How much do you give yours daily?
You’re right, Pat. There is no difference!
How much should I include in my 9 month old dog food at home!?
Can Brewers Yeast case a dog to secrete a sticky discharge after peeing??
