Brewer's Yeast Powders


Brewer's yeast is one of the most common nutritional supplements for dogs. Many breeders trust her, but some veterinarians urge caution because of its potential as an allergen. This is what you should know to decide if brewer's yeast is suitable for your dog.


Brewer's yeast is a type of nutritional yeast that is often given to dogs as a supplement. Yeasts are single-celled fungal organisms that feed on sugars and produce carbon dioxide and alcohol as by-products. They are used to bake bread and to ferment beer and wine. The specific strain used in most brewer's yeast supplements for dogs is called Saccharomyces cervisiae. Sometimes, brewer's yeast supplements are made from leftover by-products from beer making, but the highest quality supplements are made specifically for dogs from fresher ingredients.


People give their pets brewer's yeast for many reasons. First, beer yeast is a great source of B vitamins such as biotin, minerals such as zinc, proteins and amino acids. Amino acids and vitamins can help make your dog's skin healthier and its fur brighter. Second, brewer's yeast is often recommended by holistic veterinarians to help strengthen the immune system of dogs. According to the Encyclopedia of Natural Pet Care, in one study, brewer's yeast proved to protect chickens from salmon-contaminated food. Brewer's yeast is also a common natural remedy for dogs that have fleas. Holistic veterinarian Richard Pitcairn recommends it for that purpose. It is believed to act against fleas, as it contains sulfur compounds that make your dog less palatable to them. However, at least one study showed that brewer's yeast did not provide dogs with any protection compared to a control group.

Some dogs are allergic to yeast and dogs that are allergic to other foods are likely to be allergic to it as well. It is very likely that if it is of poor quality it causes allergic reactions. If your dog has food allergies, you should cautiously introduce high quality beer yeast into your diet. If you see any signs of an allergic reaction, stop administering brewer's yeast immediately.

Brewer's yeast is sold in the form of pills, tablets and as a powdered supplement that can be spread over food. The nutritional content of yeast is not standard, and may vary depending on where it is grown. Compare the labels to make sure your pet is receiving the most benefits from the product. There is also a difference between premium brewer's yeast supplements and those that are made from the by-products of the brewing process. Yeast that is specifically grown for use in supplements has more nutrients and is less likely to cause allergic reactions.

The correct dosage of brewer's yeast depends on the size of the dog and the type of yeast you are using. For powders, 1/2 teaspoon is usually recommended for every 10 kilos of body weight. The correct dosage for tablets depends on their size. Read and follow the dosage instructions on the package.
