Quick Answer

Mighty-K9 is a bacon-flavored olive oil with ESS60 (C60), sold for dogs and marketed to support joint comfort and mobility. It is not a medicine and does not treat arthritis or any condition.

Joint pain in dogs needs a vet’s diagnosis first. We found no published joint trials of ESS60 in dogs, and no long-term safety data. See the ingredients page and talk to your vet.

What Is Mighty-K9

A Bacon-Flavored Olive Oil With ESS60

The bottle is amber glass with a dropper and a cream label showing a dog’s face, the name “Mighty-K9 Canine Supplements” and the text “Organic Extra Virgin Olive Oil, Contains 100% ESS60, Bacon Flavor, Net Wt. 2 fl oz (60 mL).”

The seller says it helps with lubrication and “cellular protection.” We could not verify those claims for this product, so we describe it as marketed to support joint comfort. Read What Is Mighty-K9.

🩺 Talk to your vet first, especially if your dog…

  • is limping, stiff after rest, or reluctant to jump or climb stairs (joint pain needs a diagnosis, not just a supplement)
  • has pancreatitis, obesity, liver or kidney disease, or a sensitive stomach
  • takes anti-inflammatories, steroids, blood thinners or any prescription medicine
  • is a puppy (the seller says under six months), pregnant or nursing, or has food allergies

Never give human pain relievers such as ibuprofen, naproxen or acetaminophen to a dog unless a vet tells you to. They can be dangerous.

How To Use

A Four-Step Daily Routine

A routine to discuss with your vet, not a promise of a result.

1

Ask your vet, and get the limp checked

Rule out injury and get a diagnosis before you add a supplement. Ask about weight, exercise and proven pain relief.

2

Give it once daily with food

The seller says to mix the serving into a meal using the included dropper. The amount depends on your dog’s weight, so follow the label and the seller’s serving chart.

3

Store it dark and watch for stomach upset

Keep the bottle in its dark glass away from light. Watch for loose stools, vomiting or less appetite, and stop and call your vet if you see them.

4

Keep notes and review with your vet

Note walking, stairs and playtime for a few weeks. Review with your vet, and use the guarantee window if you see no difference.

Ingredients

What Is In The Bottle, As Far As We Can Tell

Tap an item to see what it is, what research exists, and what we could not confirm.

1ESS60 (C60 fullerene in olive oil)Marketed antioxidant · key ingredient

ESS60 is a trade name used by several brands for C60, a ball-shaped carbon molecule (fullerene) dissolved in olive oil. Rodent studies exist, with mixed findings. One reported a lifespan benefit in rats, and a later study reported light-dependent toxicity and no lifespan benefit in mice. A short regulatory-style study in rats found no adverse effects at the doses tested. We found no published joint-health trials in dogs, and no long-term safety data in dogs or people.

Amount per serving: not published in the materials we reviewed.

2Organic Extra Virgin Olive OilCarrier oil

The oil that carries the ESS60. Olive oil is a source of fat and calories. For most dogs a small amount is fine, but extra fat can cause loose stools, and it may be a problem for dogs prone to pancreatitis or weight gain. The seller’s claim that it “soothes joint inflammation” is not something we could verify.

Amount per serving: depends on the dog’s weight and the label’s directions.

3“Bacon Flavor”Flavoring named on the label

The bottle label reads “Bacon Flavor.” The seller’s page does not describe what this flavoring is. Ask what it contains if your dog has food allergies, a sensitive stomach or a salt-restricted diet.

Amount and source: not published.

4Glucosamine, Chondroitin and MSM (?)Mentioned once on the seller’s page

The seller says the product has “two ingredients,” but one passage credits “a blend of Glucosamine, Chondroitin, and MSM” for cartilage support. Both cannot be right. We cannot confirm these are in the bottle, so we do not count them.

Presence and amount: unconfirmed.

We do not publish testimonials or star ratings, because we could not verify any for this product.

💬

No verified reviews found

We found no independent reviews of this exact product to quote.

⏱️

“Results in 2 to 3 weeks” is a claim

The seller says most owners notice results then. We could not verify it, and dogs’ joint comfort changes for many reasons.

Your Plan

Help Your Dog’s Joints In Four Moves

Keep your dog lean

Extra weight loads the joints. Count the calories in oils and treats.

3

Move gently and often

Short, regular, low-impact walks beat occasional long ones.

4

Make home easier

Non-slip floors, ramps and a supportive bed help stiff joints.

The Difference

A Supplement Alone Versus A Full Plan

A supplement on its own

  • Hard to know if it helps
  • May delay finding the cause
  • Ignores weight and exercise
  • Little proof for this ingredient in dogs

A plan with your vet

  • A diagnosis first
  • Weight, exercise and home changes
  • Proven options where needed
  • A supplement as an optional extra, with notes

Common Questions

Frequently Asked Questions

What is Mighty-K9?

Mighty-K9 is a 2 fl oz (60 mL) dropper bottle of bacon-flavored organic extra virgin olive oil that contains ESS60. It is sold for dogs and marketed to support joint comfort and mobility. The label reads “Mighty-K9 Canine Supplements.” It is a supplement, not a medicine.

What is ESS60?

ESS60 is a trade name for C60 (a fullerene) dissolved in olive oil. The seller calls it a “Nobel Prize winning discovery.” The discovery of fullerenes did win the 1996 Nobel Prize in Chemistry, but that does not mean this product was tested or endorsed by anyone.

Does Mighty-K9 treat arthritis or hip dysplasia?

No. It is a supplement and is not intended to diagnose, treat, cure or prevent any condition. Joint problems in dogs need a veterinary diagnosis, and vets have proven options such as weight management, exercise plans and prescription pain relief.

Has ESS60 been shown to help dogs’ joints?

We found no published trials of C60 or ESS60 for joint health in dogs. Studies in rats and mice exist, with mixed results. The seller’s claim that it is “172× more powerful than Vitamin C” is not something we could verify for this product.

How much should I give?

The seller says once daily mixed into food with the included dropper, with the serving based on your dog’s weight using the seller’s serving calculator. We do not print doses. Follow the directions that come with your bottle and ask your vet.

Is it safe?

A short regulatory-style rat study found no adverse effects at the doses tested, but long-term safety in dogs has not been established, and one study reported that C60 in oil can become toxic when exposed to light. Keep the bottle in its dark container away from light, and talk to your vet before starting.

Which dogs should avoid it, or ask a vet first?

Ask your vet first if your dog has pancreatitis, obesity, liver or kidney disease, food allergies, or takes anti-inflammatories, steroids or blood thinners, and if your dog is a puppy (the seller says under six months), pregnant or nursing.

Is it really only two ingredients?

The seller says so, but one passage on its page also credits a Glucosamine, Chondroitin and MSM blend. Both statements cannot be right, so we treat the ingredient list as unconfirmed. Check the bottle.

How much does it cost?

We do not print a price, because the checkout reached through our link may differ from other listings. For reference, the brand’s own website listed $64.99 for one 60 mL bottle (regular $89.99) when we checked. Confirm the price, shipping and any auto-renewal at checkout.

What is the guarantee?

The offer is shown with a 60-day money-back guarantee badge. The brand’s own website describes a 30-day guarantee that requires a return authorization and shipping the bottle back, even if empty, with return shipping not included. Confirm which terms apply at checkout.

Is it organic, made in the USA and third-party tested?

The seller says it is certified organic, made in the USA in FDA-registered, GMP-certified facilities and third-party tested. We could not verify these statements. Ask for certificates, and check the bottle for the manufacturer.
