If you’re just now learning about this all-natural technique to improve your dog’s health, it’s important to familiarize yourself with all of its applications as well as any possible drawbacks.

Benefits of Brewers Yeast For Dogs

Brewer’s yeast provides a very wide range of advantages for both people and pets. But, let’s simply concentrate on what it can do for your dog.

Skin Health

B vitamins, especially B1, B2, B3, B5, B6, B7, and B9, are abundant in brewer’s yeast. These nutrients are necessary to keep the skin barrier function functioning properly. If your dog doesn’t receive enough of them, they may get alopecia, anorexia, and pruritus in addition to having dry, flaky skin.

Coat Quality

Brewer’s yeast contains a ton of antioxidants, including the crucial omega-3 and omega-6 fatty acids. They make your dog’s coat seem glossy and lustrous, and the B vitamins also maintain their hair healthy and less prone to break or fall out.

Eye Health

The same antioxidants protect your dog’s eyes from harm, reducing the risk of glaucoma, cataracts, and retinal illnesses. Brewer’s yeast is thus beneficial for older dogs, but for maximum effects, you should start giving it to your dog before their vision begins to deteriorate.

Liver Function

The use of B vitamins to enhance liver function and treat illness is now being investigated by scientists. Due to the abundance of B vitamins in brewer’s yeast, it may be able to aid in minimizing cellular damage from free radicals, reversing nutritional deficiency, and enhancing vitamin absorption.

Anxiety Reduction

B vitamins are necessary for the synthesis of serotonin, a “feel-good” neurochemical that may uplift and calm your dog. Nevertheless, brewer’s yeast may interfere with certain anti-anxiety drugs, so if you’re already treating your dog for this problem, talk to your veterinarian before feeding your pup brewer’s yeast.

Diabetes Control

This one is a little debatable. Brewer’s yeast contains chromium, which has been found to increase the body’s ability to tolerate glucose and utilise insulin in humans, but no comparable research has been done in dogs. But, there is a ton of anecdotal data that suggests it could efficiently assist dogs in controlling their blood sugar levels.

Ask your veterinarian before beginning to add brewer’s yeast to your dog’s food since it may interfere with diabetic treatments, leading to a severe reduction in insulin levels.

Cell Function

Brewer’s yeast contains B vitamins that assist your dog’s cells in converting food into energy. This gives your dog greater vigor and makes their cells function more effectively. The yeast’s antioxidants also shield cells from oxidation and other forms of free radical damage, which may have a number of positive effects at the cellular level.

Improve Digestion

Brewer’s yeast is loaded with probiotics, which are beneficial bacteria that line the digestive tract and help with food digestion, nutrient absorption, and illness prevention. This might make it a great option for dogs that have sensitive stomachs, diarrhea, or other digestive issues.

Build Lean Muscle Mass

Brewer’s yeast, which contains 52% protein by mass, is a fantastic supplement for your dog to use to develop lean muscle. Your dog should feel fuller for longer thanks to the protein, which may aid in weight reduction.

Parasite Prevention

Brewer’s yeast may aid in your dog’s ability to ward off ticks and fleas. How does it function? While it tends to work better when combined with omega-3 oils, which we don’t truly know, you may wish to combine it with fish oil or another comparable supplement. Nonetheless, you should see the parasite protection as an added benefit rather than depending on it as your only option.

Moreover, look at the contents of any brewer’s yeast product sold expressly for controlling fleas and ticks. Several of them combine the yeast and garlic to increase strength, but sadly, dogs cannot consume garlic.

Uses for Brewer’s Yeast

How can you convince your dog to consume brewer’s yeast now that we’ve seen all the advantages it can have for your dog? You have many choices.

Add It to Their Food

Considering that most brewer’s yeasts are supplied as powders, all you need to do is combine it with your dog’s food and water. Nevertheless, some dogs find the flavor to be harsh, and they may not like it. Companies do provide de-bittered brewer’s yeast, but when the chromium is removed, many of its nutritional advantages are lost.

Give Them a Pill

You may also feed your puppy brewer’s yeast tablets or capsules. They can be simpler to feed your dog since you can cover them with peanut butter or cover them in a treat. A tablet also makes it simpler to regulate the dose.

Toss Them a Chewable

Moreover, chewable brewer’s yeast pills are available. They are simple to use, but because of their harsh flavor, it could be challenging to get your dog to consume them.

Side Effects of Brewer’s Yeast

Brewer’s yeast offers a long list of advantages for dogs, but that doesn’t imply it is without cons. Let’s examine the possible adverse effects that you can experience from using this product.

Upset Stomach

Some dogs don’t take brewer’s yeast well, despite the fact that it may be used to calm upset stomachs. They may have stomach issues as a result of the supplement, which entirely negates the objective.

When you start administering your dog brewer’s yeast, you should keep a tight eye on them for a few days to make sure they aren’t throwing up, having diarrhea, or exhibiting any other gastrointestinal distress symptoms.

Yeast Infection

While it may seem clear, brewer’s yeast is really yeast. Although most dogs don’t have an issue with it, you shouldn’t feed your dog brewer’s yeast if they have impaired immune systems, are prone to yeast infections, or have allergies to yeast.

If you are unsure of how your dog will respond to yeast, keep a careful eye on them after giving them the supplement to ensure that they don’t develop rashes or dry, itchy skin. If they do, stop using the brewer’s yeast right once and get in touch with your veterinarian.

Weight Gain

Brewer’s yeast has a lot of calories, so if you feed it to your dog often to prevent weight gain, you’ll need to reduce calories elsewhere. To balance out their increased calorie intake, you may also attempt to raise their level of exercise.

Interference With Medications

Before beginning to give brewer’s yeast to your puppy, you should check with your veterinarian whether your dog is currently on any prescription drugs. It has a history of having negative drug interactions, particularly with diabetic medicines and anti-anxiety drugs.


Bloat is a dangerous, sometimes deadly condition brought on when your dog’s stomach twists after being full of gas, food, or fluids. Brewer’s yeast may cause your dog’s stomach to ferment and fill with gas, raising the possibility of bloat.

Every dog may have bloat, although broad-chested breeds like Great Danes or Mastiffs are more susceptible than others. Start with modest quantities of yeast and increase it gradually if you’re certain your dog can handle it to decrease the chance of bloat.

Is It Time to Start Giving Brewer’s Yeast to Your Dog?

Brewer’s yeast offers significant advantages for dogs, but it also has disadvantages that you should carefully examine before starting to give it to your canine companion. Prior to starting your dog on a new supplement regimen, it’s crucial that you discuss your strategy with your veterinarian.

Brewer’s yeast may turn out to be just what your dog needs, and if you prefer utilizing natural treatments to address common issues, it may be the answer you’ve been waiting for.
