Packed With High Quality Ingredients


A Proprietary Blend of Probiotics (Bacillus coagulans, B. clausii, B. subtillis)

This specific fusion of spore-forming probiotics can help maintain healthy canine gut flora, as well as support digestive and immune health.


Colostrum (Bovine)

Colostrum is a protein-rich fluid produced from mammary glands. This hugely beneficial ingredient can help support good gut microbes and healthy skin.

krill oil

Krill Oil (Omega 3, EPA, DHA)

Our Krill Oil features a mega source of omega-3 fatty acids, which directly help to support skin and coat health in dogs.


Prebiotics (FOS & GOS)

Prebiotics are just as important as probiotics! This powerful addition can help promote the growth of beneficial bacteria in the digestive system, and also acts as "food” for the probiotics. Together, FOS & GOS can also support your dog’s immune system, and help with occasional allergy discomfort.

borage oil

Borage Oil

Bursting with omega fatty acids, Borage oil can help to support skin and coat health.


Synergistic Yeast Postbiotic Blend

Lastly, we have postbiotics! Ours is a synergistic Yeast Postbiotic Blend, a multiple-strain postbiotic that can support your pet’s normal immune defenses.
