Overview

An 8 oz antioxidant oil supplement for dogs and cats made from Antarctic krill oil, dispensed with a pump, positioned by the maker for liver, respiratory, cardiovascular and vascular support.

This is a single-ingredient-style oil supplement rather than a broad multivitamin, meant to be pumped onto food. Krill itself is a crustacean, which is a detail worth knowing for pets with shellfish sensitivities.

Who it's for

For dog and cat owners looking to add an antioxidant oil to a meal routine, particularly where liver or cardiovascular support is a focus. Not a treatment for a diagnosed medical condition on its own.
