Black tea extract

Natural extract from Camellia sinensis leaves.

About

Black tea extract is derived from the leaves of Camellia sinensis through an oxidation and extraction process that concentrates the plant's characteristic aromatic compounds and polyphenols — primarily theaflavins and thearubigins, formed during the oxidation of fresh tea leaves. Black tea is one of the most consumed beverages in the world, valued both for its complex flavour profile and its well-studied polyphenol content.

In TWOZERO®, black tea extract contributes a subtle complexity to the flavour profile — adding depth that rounds out the fruity notes and creates a more sophisticated overall taste. Beyond flavour, the theaflavins in black tea extract have been studied in clinical trials for their role in supporting cardiovascular health, metabolic health, and recovery from oxidative stress — areas that matter to athletes who train hard and want to perform consistently.
