The present invention is on particular compositions comprising certain combinations of the main olive polyphenols, such as for instance oleuropein and/or ligstroside in combination with hydroxytyrosol and/or tyrosol characterized in that the ratio of non-hydrolysed polyphenols (oleuropein and/or ligstroside) to hydrolysed polyphenols (hydroxytyrosol and/or tyrosol) is within certain thresholds which unexpectedly provide certain health benefits as compared to other compositions of olive polyphenols already known in the art. In a particular embodiment of the present invention the compositions contain standardized quantities for at least two of said olive polyphenols.
