Brewer's Yeast & Garlic Tablets Supplement for Dogs
Verified Jun 16, 2026
This is a B‑vitamin and mineral supplement for dogs that uses brewer's yeast and garlic as its base. It’s designed to be given daily as turkey-flavored tablets to support general wellness, skin and coat quality, and immune health. The added B‑vitamins and trace minerals help round out the nutritional support provided by the yeast.
Nutritionally, this is a straightforward yeast- and garlic-based supplement that adds extra B‑vitamins and trace minerals on top of a regular balanced diet. It can be reasonable for otherwise healthy dogs who might benefit from a bit of extra B‑vitamin support for skin, coat, or general wellness. It is not a complete food and should only be used alongside a nutritionally balanced dog diet.

KibbleLab Review
Strengths
- Brewer’s yeast provides additional B‑vitamins, some protein, and beneficial compounds that can support skin, coat, and general vitality when used appropriately.
- Includes a range of supplemental B‑vitamins and trace minerals (iron, manganese, copper, zinc, etc.) to help support normal metabolic and immune function.
- Turkey flavor and tablet form make it relatively easy to give directly or crush into food for most dogs.
- Simple, focused ingredient list without artificial colors or sweeteners.
Considerations
- This is a supplement, not a complete diet, so it should only be used along with a complete and balanced dog food and not as a primary nutrition source.
- Garlic is included; while the amount per tablet is low, dogs with a history of anemia, certain breeds with red blood cell sensitivities, or pets on specific medications should only use garlic-containing products under veterinary guidance.
- Brewer’s yeast and garlic can be problematic for some dogs with yeast issues or specific food sensitivities, so monitor for any gastrointestinal upset or skin changes when starting it.
- The added vitamins and minerals are on top of what’s already in your dog’s food, so if your dog is on other supplements, it’s worth checking with your vet to avoid unnecessary overlap.

Top 5 Ingredients Explained
01
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
02
Garlic
Garlic is sometimes used in pet foods as a flavoring or for claimed immune or antiparasitic effects, but it is not an essential nutrient for dogs or cats. Because garlic (and other Allium species) contains compounds that can cause oxidative damage to red blood cells and potentially trigger hemolytic anemia—cats are particularly sensitive—its inclusion is controversial and exposure should be avoided or discussed with your veterinarian.
03
Iron
Iron is an essential trace mineral used in pet foods to support oxygen transport (hemoglobin and myoglobin), energy metabolism and various enzyme functions in dogs and cats. Adequate iron prevents anemia and poor growth, but excess intake can cause gastrointestinal upset or toxicity—especially in young animals—and absorption can be influenced by other dietary minerals, so commercial diets are carefully formulated to meet species-specific needs.
04
Iron Amino Acid Chelate
Iron amino acid chelate is a chelated form of iron used in pet foods as a bioavailable mineral supplement to support hemoglobin formation, oxygen transport and iron-dependent enzymatic functions. Because the amino-acid chelation improves absorption and often reduces gastrointestinal irritation and interactions with other minerals compared with inorganic iron salts, it is used to prevent or correct iron deficiency in dogs and cats, but must be included at appropriate levels and formulated to nutritional guidelines to avoid iron excess or toxicity.
05
Niacin
Niacin (vitamin B3) is a water‑soluble B vitamin included in pet foods as an essential nutrient for energy metabolism and for maintaining healthy skin, nervous system, and digestive function. Dogs can make some niacin from tryptophan, but cats have a limited ability and therefore need sufficient dietary niacin; deficiencies cause poor growth, dermatitis and gastrointestinal or neurological signs, while very high supplemental doses can cause gastrointestinal upset or, rarely, liver issues, so it is normally provided at balanced levels in vitamin premixes.
