What Is a Polyphenol Supplement?

A polyphenol supplement delivers concentrated plant polyphenols in capsule or liquid form. Unlike general antioxidant supplements, polyphenols work through multiple biological pathways—supporting cellular health, inflammation balance, cardiovascular function, and brain health.

Polyphenols occur naturally in:

  • Olives and olive oil
  • Fruits and vegetables
  • Tea, wine, cocoa, and herbs
  • However, modern diets often fall short of therapeutic polyphenol levels, which is why supplementation has gained attention.
