The Active Ingredient Is: Theaflavins

Theaflavins are polyphenolic compounds found in black tea that contribute to antioxidant activity and support arterial health. This extract provides a standardised concentrate of theaflavins, with thearubigins also present, within a vegetarian capsule.

The form is a black tea extract, licensed for use as a plant-derived polyphenol supplement and suitable for a wide range of users.

What Does Theaflavins Do?

Theaflavins aid in antioxidant protection and contribute to healthy cholesterol metabolism and arterial function, in line with EFSA-style guidance on polyphenol effects.

Dr. Davies of the University found that daily supplementation with a theaflavin-enriched extract improved cholesterol profiles in healthy adults, supporting vascular function and circulation.
