C60 is not absorbed into the body unless it is dissolved in something. C60 is virtually insoluble in water but with a lot of effort it will dissolve in olive oil. From the Paris study extra virgin olive oil was used as it was deemed to be harmless. Olive oil indeed contains substances such as polyphenols which are health giving. C60 is a strong antioxidant, much more potent than vitamin C and E. The antioxidant properties are thought to be the main way it achieves it beneficial effects. However this may not be the only way, C60 and olive oil may work together to achieve the observed benefits. This is a subject for further research.
