C60 for Dogs: What the Research Really Shows

Nobody knows yet, because the right study has not been done. C60 research is small, mostly in rodents, and points in different directions.

C60 is a ball-shaped molecule of 60 carbon atoms, and ESS60 is a trademarked form of it. Mighty K9 carries 1.6 mg of ESS60 in each 2 mL serving of olive oil. The sales page says it protects cells and supports joints.

The 1996 Nobel Prize in Chemistry went to the scientists who discovered fullerenes (Nobel Prize, 1996). It was not a health finding.

Rats given C60 in olive oil had an estimated median lifespan of 42 months, against 26 on olive oil alone and 22 on water (Baati et al., 2012).

• Tiny groups: three groups of 6 rats, so a few deaths swing the result.
• Dose: 1.7 mg/kg, daily at first, then weekly, then every 2 weeks.
• Not repeated: no independent team has reproduced it, and joints were not studied.

It is a personal call on thin data: 18 rats for, a larger mouse study against.

If you try Mighty K9, store it dark, count the calories and use the 30-day empty-bottle guarantee if it is not a fit. Possible upsets are on our Mighty K9 side effects page.

Estimated median lifespan 42 months with C60 in olive oil vs 26 months with olive oil and 22 with water. Dose 1.7 mg/kg, given daily, then weekly, then every 2 weeks.
2. C60 in olive oil causes light-dependent toxicity and does not extend lifespan in mice. Grohn KJ, et al. GeroScience 43(2):579-591, 2021.No lifespan gain: median 144 vs 145 weeks (p=0.87) and 127 vs 130/128 weeks. C60 oil exposed to light for 4-8 days killed 25-50% of mice. Commercial products varied from 0.57 to 1.4 mg/mL.
