This study found significant discrepancies between commercially obtained C-60-OO and in-house prepared C-60-OO, suggesting potential risks of toxic species formation under light exposure, no impact on lifespan from intraperitoneal injections of C-60-OO in mice, and lack of significant benefits in lifespan and health span from oral treatment with C-60-EVOO or EVOO supplementation in mice.
C-60 is a potent antioxidant that has been reported to substantially extend the lifespan of rodents when formulated in olive oil (C-60-OO) or extra virgin olive oil (C60-EVOO). Despite there being no regulated form of C-60-OO, people have begun obtaining it from online sources and dosing it to themselves or their pets, presumably with the assumption of safety and efficacy. In this study, we obtain C-60-OO from a sample of online vendors, and find marked discrepancies in appearance, impurity profile, concentration, and activity relative to pristine C-60-OO formulated in-house. We additionally find that pristine C-60-OO causes no acute toxicity in a rodent model but does form toxic species that can cause significant morbidity and mortality in mice in under 2 weeks when exposed to light levels consistent with ambient light. Intraperitoneal injections of C-60-OO did not affect the lifespan of CB6F1 female mice. Finally, we conduct a lifespan and health span study in males and females C57BL/6 J mice comparing oral treatment with pristine C-60-EVOO and EVOO alone versus untreated controls. We failed to observe significant lifespan and health span benefits of C-60-EVOO or EVOO supplementation compared to untreated controls, both starting the treatment in adult or old age. Our results call into question the biological benefit of C-60-OO in aging.
