What Is Brewer’s Yeast and Is It Safe for Dogs?
Brewer’s yeast is a natural ingredient best known for its rich nutritional profile. Traditionally used in brewing and as a health supplement, it’s packed with B vitamins, amino acids, and antioxidants that support overall wellbeing.
The good news? Brewer’s yeast can also be safe and highly beneficial for dogs when given in the right form and dosage. That’s why many canine nutritional supplements now include brewer’s yeast to promote skin, coat, and digestive health.
Types of yeast used in dog supplements
Not all yeast is the same. The two most common types used in dog products are:
-
Brewer’s Yeast (Saccharomyces cerevisiae) – the most widely used form in dog supplements. It’s rich in B-complex vitamins, selenium, and protein, supporting immunity, skin, and energy.
-
Nutritional Yeast – a deactivated form of yeast that also contains high levels of vitamins and minerals. It’s often used as a natural flavour enhancer while providing similar benefits.
Most commercial dog supplements use brewer’s yeast because it has been studied more for its safety and effectiveness in pets.
