Mighty K9 FAQ: Quick Answers for Dog Owners

Mighty K9 is a liquid supplement for dogs: organic extra virgin olive oil containing ESS60, a form of C60 fullerene, with bacon flavor. It comes in a 60 mL amber glass dropper bottle. It is not a chew, a capsule or a veterinary drug.

Three ingredients appear on the label: extra virgin olive oil, ESS60 and bacon flavor. The bottle front says the olive oil is organic. Each 2 mL serving holds 1.6 mg of ESS60, and the rest is almost entirely oil.

ESS60 is a trademarked form of C60, a round carbon molecule made of 60 atoms, dissolved in oil. The label marks it as not recognized as an essential nutrient by AAFCO dog food profiles. Each serving holds 1.6 mg.

The sales page says it supports joint function, mobility, everyday stiffness, antioxidant cellular protection, energy, and skin and coat. Those are the brand's claims. No study has tested C60, ESS60 or Mighty K9 for dog joints.

No. The label says for canine use only, and the bacon-flavored oil is made for dogs. Keep it out of reach of children and other animals.

Its base is olive oil, a normal food fat, but C60 safety data are short-term and come from rats and mice. Long-term safety in dogs is unknown. Ask your vet first, especially for puppies, dogs on medicine or dogs prone to pancreatitis.

The sales FAQ says puppies under 6 months should see a vet first. Growing dogs get their fat and calories from puppy food. Let your vet decide whether any extra oil fits.

Ask your vet before combining it with carprofen, Rimadyl or any other medicine. No interaction study exists. Vet-prescribed anti-inflammatory drugs are the most predictably effective treatment for arthritis pain, so do not swap one for a supplement.

Talk to your vet first, because each serving is about 1.8 g of pure fat. Dogs with pancreatitis often need low-fat diets, and extra fat can cause vomiting and diarrhea in some pets.

See a vet for limping, crying out, trouble rising, or stiffness that does not ease. Those can be signs of pain, injury or arthritis. A supplement cannot tell you the cause, and it is not pain relief.

No. Pet supplements do not get FDA review before sale; they are regulated as animal food or drugs. You can report a problem through the FDA Safety Reporting Portal.
