Brewers Yeast for dogs

Brewers Yeast for Dogs: What is it and what are the benefits?

Brewers Yeast is a supplement derived from the Saccharomyces cerevisiae fungus. It's a rich source of B vitamins, minerals, and amino acids. Benefits include improved coat health, repelling fleas, and overall well-being.

What is Brewers Yeast?

Brewers Yeast is a type of yeast, specifically Saccharomyces cerevisiae, that is used in the brewing and baking industries. It is a one-celled fungus and is a byproduct of beer production. Brewers Yeast is known for its high content of B vitamins, particularly B-complex vitamins like B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), and B7 (biotin). It also contains minerals and protein.

The Benefits of Brewers Yeast for Dogs

Brewers Yeast offers several potential benefits for dogs when used as a dietary supplement, including:


  • Nutrient-Rich: Brewers Yeast is packed with B vitamins, minerals, and protein, which can contribute to your dog's overall health and well-being.
  • Improved Coat Health: The B vitamins in Brewers Yeast, particularly biotin, can promote healthy skin and a shiny, lustrous coat. This is especially beneficial for dogs with skin or coat issues.
  • Repelling Fleas: Some believe that the odour produced by the ingestion of Brewers Yeast can make a dog less appealing to fleas. While it's not a foolproof flea prevention method, it may help in combination with other preventive measures.
  • Immune Support: Brewers Yeast contains nutrients that can support a dog's immune system, potentially helping them better fend off illness.
  • Energy Boost: The B vitamins in Brewers Yeast can aid in energy production, which may be beneficial for active dogs or those with increased energy needs.
  • Digestive Health: The dietary fibre in Brewers Yeast can support healthy digestion in dogs.
It's important to note that the benefits of Brewers Yeast can vary from one dog to another, and individual responses may differ. Also, while it can be a valuable supplement, it should not replace a balanced and complete dog food.

How to use Brewers Yeast as a supplement

Using Brewers Yeast as a supplement for your dog is relatively simple. Here are the typical steps:


  • Choose a High-Quality Brewers Yeast: Ensure you select a reputable and high-quality Brewers Yeast supplement specifically formulated for dogs. Avoid using Brewers Yeast intended for baking or brewing, as it may not be safe for pets. Supplements such as Herbal Dog Co Seasonal Soother contain Brewers Yeast as part of their natural mix.
  • Determine the Correct Dosage: Consult with your holistic veterinarian or supplement supplier to determine the appropriate dosage for your dog based on their size, age, and specific health needs. Dosages can vary, and it's crucial to avoid overfeeding.
  • Incorporate into Meals: Brewers Yeast supplements often come in various forms, such as tablets, powder, or chewable treats. Follow the product's instructions for administration. You can mix the powder form into your dog's food or give them the chewable treats as directed.
  • Monitor for Any Reactions: Keep an eye on your dog for any adverse reactions or allergies when introducing a new supplement. Common side effects are rare, but they can include gastrointestinal upset or skin reactions.
  • Combine with a Balanced Diet: Brewers Yeast should complement your dog's regular balanced diet. It's not a replacement for their main food, but rather a supplement to enhance their nutrition.
Remember that while Brewers Yeast can offer potential benefits, not all dogs may need it, and the specific benefits may vary from one dog to another.

Can Brewers Yeast make a yeast imbalance worse in a dog?

Brewers Yeast is generally safe for dogs when used in moderation and for its intended purposes as a dietary supplement. It is often used to support skin and coat health and provide essential nutrients. However, there is a theoretical concern that using Brewers Yeast in dogs with preexisting yeast-related issues, such as yeast infections or overgrowth, might exacerbate the problem.

The concern arises because Brewers Yeast is a type of yeast, and its introduction may provide additional nutrients to yeast organisms. While there is no direct evidence to suggest that Brewers Yeast will worsen yeast imbalances in dogs, it's essential to exercise caution and consult with a holistic veterinarian in such cases.

If your dog is prone to yeast infections or has an existing issue, it's advisable to seek professional guidance. Your holistic veterinarian can provide specific recommendations for managing and addressing yeast-related problems and whether the use of Brewers Yeast is appropriate in your dog's situation. They may also suggest alternative supplements or treatments that won't potentially worsen the imbalance.

At what age can I give my dog Brewers Yeast?

The age at which you can give your dog Brewers Yeast can vary depending on the individual dog and their specific dietary needs. In general, Brewers Yeast is considered safe for dogs of all ages, including puppies. However, there are some considerations:

Puppy Age: If you plan to introduce Brewers Yeast to a puppy, it's advisable to wait until they are weaned and have transitioned to solid food. Typically, this occurs at around 6 to 8 weeks of age.
Consult Your Veterinarian: Before adding any dietary supplement, including Brewers Yeast, to your dog's diet, it's a good practice to consult with your holistic veterinarian. They can provide guidance on the appropriate age and dosage for your specific dog, taking into consideration their breed, size, and overall health.

Use in Moderation: Regardless of your dog's age, it's important to use Brewers Yeast in moderation. The dosage may vary based on your dog's age and specific nutritional needs, so follow your veterinarian's recommendations.

Monitor for Allergies or Reactions: When introducing any new supplement, observe your dog for any adverse reactions, especially in puppies. While rare, some dogs may have sensitivities or allergies to certain ingredients.


In conclusion, Brewers Yeast can be a valuable addition to a dog's diet when used thoughtfully. It offers potential benefits, such as improved skin and coat health, potential flea repellent properties, and nutritional support. However, its usage should be in moderation, and the individual needs of each dog should be considered.

While brewer's yeast can enhance a dog's nutrition, it should not replace a balanced and complete dog food.
