Polyphenols

Plant defense compounds that protect your cells too.

Polyphenols are bioactive compounds found in colorful plant foods that act as powerful antioxidants and anti-inflammatory agents. They activate longevity pathways like AMPK and sirtuins, protect against cardiovascular disease, and support gut microbiome diversity. The PREDIMED trial showed that a polyphenol-rich Mediterranean diet supplemented with extra virgin olive oil reduced cardiovascular events by 30%.
