    Often considered nature's perfect antioxidant, hydroxytyrosol is one of the key active ingredients in the olive that is largely responsible for the olive's tremendous health benefits. Hydroxytyrosol is a natural phytochemical with the highest antioxidant properties discovered to date.* Hydroxytyrosol has an ORAC value (Oxygen Radical Absorbance Capacity - its ability to absorb cell-damaging free radicals) of 68,576 - which is considered to be 15 times higher than green tea and 3 times higher than CoQ10.

    A small molecule rapidly absorbed into the bloodstream and tissues, hydroxytyrosol is also able to cross the blood-brain barrier, supporting systemic defense against free radical damage.* ProHealth's Hydroxytyrosol Extreme™ contains 25mg of hydroxytyrosol per capsule, derived from cultivated organic olive leaf.

    Nice small capsules with adequate declaration of the amount of Hydroxytyrosol per capsule.

    Dennis W.

    I am absolutely clueless as to what advantages these supplements are providing me. That said, I take about 21 supplements every morning and I have no idea that one single supplement provides any benefit other than in my mind. The supplements I take have been thoroughly researched and I considered them all to have benefits but after years of taking them, I do not feel one bit healthier. However, my parents do the same thing, and say the same thing. But, they are both in their mid 90's and they are still independent, with no health issues wht-so-ever. Amazing, huh? So, I'll keep taking these and all the others and perhaps I will outlive them both (although I am developing serious doubts about that! :>)
