The label line
What is in Mighty K9?
Mighty K9 contains three things: olive oil, ESS60 and a bacon flavor. The ingredient line on the label reads, word for word: "Extra Virgin Olive Oil, ESS60 and Bacon Flavor."
The bottle front adds two details. It calls the oil "Organic Extra Virgin Olive Oil," and it says the bottle "Contains 100% ESS60®." ESS60 is a trademarked form of C60 fullerene, a round molecule made of 60 carbon atoms.
Each bottle holds 60 mL (2 fl oz) dropper bottle, or 30 servings of 2 mL. There are no fillers or binders to sort through.

Amounts
How much of each ingredient is in one serving?
Almost the whole 2 mL serving is olive oil. The label lists ESS60 at 1.6 mg per serving and gives no amount for the bacon flavor.
| Ingredient | Per serving | What research has looked at | Evidence |
|---|---|---|---|
| Organic extra virgin olive oil | Nearly the whole 2 mL serving | 884 kcal per 100 g; 0 g EPA or DHA (USDA) (USDA, Olive oil) (Merck Vet Manual, Pancreatitis) (ASPCA, People foods) | Food ingredient; no dog joint trials |
| ESS60 (C60 fullerene) | 1.6 mg per 2 mL serving (Guaranteed Analysis) | Rats 1.7 mg/kg; mice about 4 mg/kg; one 9-day study in 6 beagles (Baati et al., 2012) (Grohn et al., 2021) (Burres et al., 2024) (Hui et al., 2023) (PubMed search, C60 and dogs) | Very limited, animal studies only |
| Bacon flavor | Not stated | No research dose; added for taste (AAFCO, Reading labels) | Not applicable, taste only |
Two mL of olive oil weighs about 1.8 g. So 1.6 mg of ESS60 is less than one-tenth of 1% of each serving by weight.
Reading order
Why are the Mighty K9 ingredients listed in that order?
Pet food labels list ingredients from the most to the least by weight. That is why olive oil comes first and the flavor comes last (AAFCO, Reading labels).
ESS60 is the headline on the sales page, but by weight it is a trace. The flavor comes after it, so it is likely a small amount too.
The bottle front phrase describes the type of C60 used. It does not mean the liquid is 100% ESS60. The panel shows 1.6 mg of ESS60 in each 2 mL, which works out to about 0.8 mg per mL.
The Guaranteed Analysis also marks ESS60 with an asterisk. The footnote says it is "not recognized as an essential nutrient by the AAFCO Dog Food Nutrient Profiles." In plain words, dogs have no known dietary need for it. The full label walk-through covers each line.
Left out
What is not in Mighty K9?
Mighty K9 has no glucosamine, no chondroitin, no fish oil, no MSM and no turmeric. Many joint products use them. This one does not.
| Ingredient | In Mighty K9? | What dog research says |
|---|---|---|
| Fish oil (EPA and DHA omega-3) | No | The one joint nutraceutical with good dog evidence (AAHA, Pain guidelines) (Barbeau-Gregoire et al., 2022) |
| Glucosamine | No | A 72-trial review found a marked non-effect for chondroitin-glucosamine (Barbeau-Gregoire et al., 2022) |
| Chondroitin | No | Same review as above |
| MSM | No | Not in the label line |
| Turmeric (curcumin) | No | Not in the label line |
| Green-lipped mussel | No | Not in the label line |
The biggest gap is omega-3. Olive oil is mostly monounsaturated fat and has 0 g of EPA and 0 g of DHA (USDA, Olive oil). If your vet has suggested fish oil for your dog's joints, Mighty K9 does not replace it. See Mighty K9 vs fish oil for a side-by-side.

Sensitivities
Does Mighty K9 contain common dog allergens?
The label lists no chicken, beef, dairy, wheat, soy or egg. The one open question is the bacon flavor, because the label does not say what it is made from.
Food allergies in dogs are usually reactions to proteins. Olive oil shows 0% crude protein on the panel. A flavor is different: the bottle does not say what it comes from.
The maker's support email, as listed on the brand's sales page, is [email protected]. Ask what the bacon flavor is made from and keep the reply for your vet.
Each serving adds about 1.8 g of fat. Extra fat can cause vomiting and diarrhea, and potentially pancreatitis, in some pets (ASPCA, People foods). If your dog has had pancreatitis or eats a low-fat diet, ask your vet before you start (Merck Vet Manual, Pancreatitis).
Fair view
Is the Mighty K9 ingredient list good or bad?
The list is short and fully printed, which is a real strength. The weak spot: the active ingredient has almost no dog research.
In its favor
- Only three ingredients, all named on the label
- Full Guaranteed Analysis printed, with calories
- Organic extra virgin olive oil is a normal food fat
- Bacon flavor helps picky dogs accept it on food
- Amber glass bottle and "cool and dark" storage, which suits C60 oil
Weak spots
- No study of ESS60 or C60 for dog joints, mobility or aging (PubMed search, C60 and dogs)
- C60 safety data is short-term and partly seller-funded (Burres et al., 2024)
- No omega-3, the joint nutrient with the best dog data
- Bacon flavor source not listed
- Adds 16.2 kcal a day, which matters for small dogs
Before you start
What should I ask my vet about these ingredients?
Bring a photo of the label to your next visit. Three short questions cover most dogs.
Are the extra calories a problem?
For a 25 lb Beagle mix, 16.2 kcal is small. For a 7 lb Yorkie it is about 6% of the day.
Is extra fat safe for my dog?
This matters most for dogs with stomach trouble or a prescribed low-fat food.
Should my dog get omega-3 instead or as well?
If joints are the goal, ask whether a fish oil product fits your dog better. Limping, crying out, trouble rising, or stiffness that does not ease need a vet exam, not just a supplement.
FAQ
Mighty K9 ingredients FAQ
Which ingredients does Mighty K9 contain?
Mighty K9 lists three ingredients: extra virgin olive oil, ESS60 and bacon flavor, in that order. The bottle front says the olive oil is organic. Each 2 mL serving holds 1.6 mg of ESS60 and 16.2 kcal, and the label gives no amount for the flavor. Nothing else is listed.
Does Mighty K9 have glucosamine or chondroitin?
No. Mighty K9 contains no glucosamine and no chondroitin, and it also has no MSM, turmeric or green-lipped mussel. It is olive oil with ESS60 and a bacon flavor. For those classic joint ingredients, ask your vet about a different product.
Is there fish oil or omega-3 in Mighty K9?
No. The oil in Mighty K9 is olive oil, which has 0 g of EPA and 0 g of DHA per USDA data. Those two omega-3 fats are the joint nutrients with the strongest dog research. Mighty K9 does not replace a fish oil your vet has suggested.
What is the bacon flavor in Mighty K9 made from?
The label does not say. It lists only "Bacon Flavor" with no source and no amount. That is common on pet products. If your dog has a pork allergy or is on an elimination diet, email the maker at the address on the sales page and ask before you start.
Why is ESS60 listed second if it is the main ingredient?
Labels list ingredients by weight, heaviest first. ESS60 is only 1.6 mg in each 2 mL serving, so the olive oil far outweighs it. The sales page treats ESS60 as the star, but by weight the product is almost all oil.
Are Mighty K9 ingredients safe for dogs?
Olive oil is a common food fat, but it adds calories and fat that can upset some dogs. ESS60 has only short-term animal safety data, including one 9-day study in 6 beagles. Ask your vet first if your dog has had pancreatitis, takes medicine, or is under 6 months old.
