Is c60 safe for human consumption (edible)?

We sell c60 in a purified powdered state and this form of it has not been tested on humans. C60 olive oil has not been tested on humans. There’s an article available (The prolongation of the lifespan of rats by repeated oral administration of [60] fullerene – ScienceDirect) that suggest Carbon 60 (c60 or Buckyballs) dissolved in extra virgin olive oil works for anti-aging. The reports indicate it was successfully tested on rats and the rats that received the treatment lived twice as long as rats without the treatment.
