Bacillus Coagulans

From Fermented Foods like Yogurt

Bacillus coagulans is a resilient probiotic that survives heat and stomach acid to reach the intestines alive. Once there, it supports healthy gut balance, reduces inflammation, and strengthens immune response for better digestion and overall well-being in dogs.

Bioactive whey protein provides highly digestible amino acids that support muscle repair, growth, and immune strength. Its natural bioactive compounds also promote tissue recovery and help maintain lean body condition in dogs.

bovine colostrum

Bovine Colostrum

From First Milk Produced by a Cow

Bovine colostrum is rich in antibodies, growth factors, and immune peptides that strengthen gut integrity and boost immune defenses. It helps protect against pathogens, supports faster recovery, and promotes overall vitality in dogs.

Chondroitin

From Animal Cartilage

Chondroitin helps protect and cushion your dog’s joints by maintaining healthy cartilage and reducing inflammation. It supports mobility, flexibility, and long-term joint comfort—especially in active or aging dogs.

DHA/EPA – Omega 3 Fatty Acids

From Fatty Fish, Algae

DHA and EPA are omega-3 fatty acids that reduce inflammation, support joint flexibility, and promote healthy skin and coat. They also enhance brain and heart function, making them essential for overall wellness in dogs.

flaxseed

Flaxseed

From Flax Plants

Flaxseed is rich in omega-3 fatty acids and fiber that support healthy skin, a shiny coat, and smooth digestion. It also provides natural anti-inflammatory benefits that promote joint and heart health in dogs.

Glucosamine

From Shellfish, Bone Marrow, Plant Based

Glucosamine supports joint health by nourishing and rebuilding cartilage, reducing inflammation, and improving mobility. It’s especially beneficial for active, large-breed, or aging dogs prone to stiffness or joint discomfort.

mixed tocopherols

Mixed Tocopherols

From Sunflowers, Leafy Greens

Mixed tocopherols are natural forms of vitamin E that act as powerful antioxidants, protecting cells from oxidative damage. They help maintain a healthy immune system, support skin and coat health, and naturally preserve nutrients in dog supplements.

tapioca

Tapioca

From Cassava Root

Tapioca contains resistant starch, a special type of carbohydrate that resists digestion in the small intestine and instead ferments in the colon. This fermentation process feeds beneficial gut bacteria, producing short-chain fatty acids that strengthen the intestinal lining, reduce inflammation, and support overall digestive health in dogs.

taurine

Taurine

From Animal Tissue

Taurine is an essential amino acid that supports heart health, eye function, and overall metabolism in dogs. It also aids in muscle development and helps maintain a strong, healthy cardiovascular system.
