Overview
A 120 count chewable wheat-flavored antioxidant supplement for dogs from Vet Classics, combining wheat grass, alfalfa powder, vitamin C, green tea powder, astragalus, NAC, alpha lipoic acid, coenzyme Q-10, selenium and vitamin E.
The formula stacks several antioxidant ingredients rather than relying on a single compound, with coenzyme Q-10 at 2 mg per tablet as the smallest named dose on the label. Green tea powder is included, which the label itself flags as containing caffeine, worth noting for sensitive dogs.

Who it's for
Owners looking for a general antioxidant chew to support an aging dog's overall wellness. Not a fit for dogs sensitive to caffeine, given the green tea powder content.
