but c60 is tested by nasa to protect astronauts from radiation when they go in space
Would you have a reference for that? I can only find this document, which says a C60 derivative called C60-serinol is being proposed as a radiation protection treatment, and has been tested in mice (but not humans).
They say C60-serinol "has been made biocompatible by decorating it with a serinol malonamide to dramatically increase its water solubility (>250 mg/ml) and (ii) readily traverses physical barriers within tissues and cells to achieve excellent concentrations in all tissues within the body."
So this highly bioavailable C60-serinol being investigated by NASA is not the same as regular C60.
Be aware that one study discussed on this thread and this thread found that a commercially-available C60 product caused increased tumor growth in a rat study.
However, it appears this may not be due to the C60, but may be due to the formation of C60 epoxides that occurs when C60 in olive oil is exposed to light during manufacturing or storage. C60-OO is light sensitive and can form these toxic epoxides as a result of light exposure.
