Key facts at a glance
- Ingredients, in order: Extra Virgin Olive Oil, ESS60 and Bacon Flavor.
- Per 2 mL serving: 1.6 mg ESS60 and 16.2 kcal ME. 30 servings per container.
- ESS60 carries an AAFCO footnote: not recognized as an essential nutrient for dogs.
- There is no Supplement Facts panel. Pet products use the Guaranteed Analysis format (AAFCO, Reading labels).
- Not published: bacon flavor source and amount, organic certifier, GMP certifier, third-party lab report.
- Lot MK-26/TH-4089 and CoA reference MK-4089-26-TH are seller codes, not lab proof.
What is on the Mighty K9 ingredients list?
Three things. Extra virgin olive oil, ESS60 and bacon flavor, listed in that order. The bottle front calls the olive oil organic and says the bottle contains 100% ESS60.
That 100% on the front is a claim about the form of the ESS60 used. It does not mean the bottle is all ESS60. The panel says 1.6 mg per 2 mL serving, so the oil is nearly everything else.
| Ingredient | Role | What is not published |
|---|---|---|
| Extra virgin olive oil | Carrier for the ESS60. Almost the whole bottle. | Organic certifier is not shown to us |
| ESS60 (C60 fullerene) | The active the brand sells as an antioxidant | Lab report for amount and purity |
| Bacon flavor | Taste only | What it is made from, and how much |
How do I read the Guaranteed Analysis?
Pet labels follow feed rules, not human supplement rules. The format states the least crude protein and fat and the most fiber and moisture (AAFCO, Reading labels). Crude names the lab method, not how good the ingredient is.
| Line | Value | What it means |
|---|---|---|
| Crude protein (min) | 0% | No protein inside |
| Crude fat (min) | 100% | The liquid is all fat, as an oil would be |
| Crude fiber (max) | 0% | No plant fiber |
| Moisture (max) | Less than 0.1% | Almost no water, so not a water tincture |
| ESS60 * | 1.6 mg | About 0.8 mg per mL |
| Calories (calculated) | 16.2 kcal ME | From 8,100 kcal ME per kg |
The asterisk leads to this footnote: not recognized as an essential nutrient by the AAFCO Dog Food Nutrient Profiles. It is a standard label rule. It is not a safety warning. It only says dogs have no known dietary need for ESS60.

How are the 16.2 calories worked out?
Start from the label figure of 8,100 kcal ME per kg. A serving counted as 0.002 kg gives 16.2 kcal, which treats 2 mL as 2 g.
Olive oil is slightly lighter than water, so 2 mL is nearer 1.8 g, which would give about 15 kcal. Either way the amount is small. For a 10 kg dog the serving is 2.6% of a typical day. For a 3 kg dog it is 6.3%. The same 2 mL goes to every dog.
About 1.8 g of fat per serving is the figure on this site's side effects page. Count it if your dog is on a diet.
Is there a Supplement Facts panel?
No, and that is expected. The Supplement Facts panel belongs to human products under the 1994 supplement law. Pet supplements sit outside that law and follow the animal feed format (FDA, Pet food rules).
| Point | Pet: Guaranteed Analysis | Human: Supplement Facts |
|---|---|---|
| Governing rules | Animal feed rules in the AAFCO format | Human dietary supplement law |
| What it lists | Minimum protein and fat, maximum fiber and moisture | Amount per serving and percent Daily Value |
| Footnote use | Asterisk for a non-essential nutrient | Dagger when no Daily Value exists |
What does the label leave out?
- Lot number and best-by date: not on the panel image. The seller gives lot MK-26/TH-4089. Ask the order desk to match it to your order.
- Dose by weight: none. The panel lists a single 2 mL serving for all dogs.
- Bacon flavor source: not published. Ask the maker if your dog has a food allergy.
- Third-party lab report: not published. The CoA reference MK-4089-26-TH is a file number to ask about, not a result.
- GMP certifier: the product page says GMP-certified but names no one. No NASC Quality Seal is shown (NASC, Quality Seal).
Why does the lab report matter? Commercial C60 oils tested in a mouse study held anywhere from 0.57 to 1.4 mg per mL (Grohn et al., 2021). This label works out to 0.8 mg per mL. Without an outside test, that figure rests on the company's word.
Does it contain common dog allergens?
The label lists no meat, grain, dairy or egg. That does not clear the bacon flavor, because its source is not published. Flavors can be built from meat, smoke, yeast or other bases.
If your dog has a known pork allergy, treat the flavor as unknown until the maker answers. If your dog is on an elimination diet, ask your vet first. Watch for itching, ear flare-ups or loose stool over the first weeks.
Is the ingredient list good or bad?
It is short, and that is a strength. A three-item list is easy to check and easy to explain to a vet. The label also prints calories, which many supplements skip.
It is not a list that shows the product works. No ingredient on it has a dog joint study. See what the research says about ESS60 on the ESS60 page.
One more habit helps. Photograph the label and the lot when the box arrives. If your dog ever has a reaction, your vet and the FDA both ask for those details.

Frequently asked questions
What are the ingredients in Mighty K9?
Extra virgin olive oil, ESS60 and bacon flavor. Organic is the bottle front's word for the oil. A 2 mL serving holds 1.6 mg of ESS60.
Is there a Mighty K9 supplement facts panel?
No. Pet supplements use a Guaranteed Analysis, not the human Supplement Facts panel. It lists protein, fat, fiber, moisture, ESS60 and calories per 2 mL serving.
What does 100% crude fat mean?
It means the liquid is oil and little else. Olive oil is fat, and the ESS60 and flavor are too small to move the figure.
What does the asterisk on ESS60 mean?
It points to a footnote: not recognized as an essential nutrient by the AAFCO Dog Food Nutrient Profiles. It is a labeling rule, not a safety finding.
Where is the lot number on the label?
No lot number shows on the panel image. The seller reference is MK-26/TH-4089. Call +1 (302) 200-3480 with your order ID to match a bottle to an order.
Is the Mighty K9 formula tested by a lab?
No third-party lab report is published. You can ask the order desk about a certificate for your lot.
Our view
Our view: the label is clear and short, which we like. It tells you how much oil and how much ESS60 are in a serving. What it cannot tell you is whether the ESS60 is what the front says or whether it helps a dog.
Read the panel, ask for the lab report, and keep the lot number. That is all a careful owner can do.

Mighty K9 is not FDA approved, and no dog supplement is. It is not intended to diagnose, treat, cure or prevent any disease. Talk to your vet about any health question. Limping, pain or stiffness that does not ease needs a vet exam, not just a supplement. Ask your vet first if your dog is under 6 months, has had pancreatitis or needs a low-fat diet, is pregnant or nursing, takes any medicine, or is being treated for a condition.
