Tea Polyphenols

Tea Polyphenols

Tea polyphenols is the umbrella name for mixed tea phenols, including catechins, theaflavins, and phenolic acids, used for vascular oxidation markers and metabolism-related nutrition.

Primary

Supports vascular oxidation markers

Green-tea catechins and black-tea theaflavins can both affect blood-lipid oxidation and endothelium-related markers; mixed phenols walk this circulatory antioxidant path more broadly. People attending to vessel aging whose diet runs oily more often see change in labs and a lighter body feel after several continuous weeks.

Primary

Supports metabolism and energy expenditure

Tea-polyphenol complexes have also been watched in trials for fat oxidation, waist circumference, and how metabolism feels after a meal; theaflavins put fermented tea on this same path. For people whose metabolism slows with sitting and who want to start from everyday tea phenolics, differences in stamina and girth are more often noticeable after several weeks of continued use.

Dyslipidaemia

Green-tea catechins and black-tea theaflavins can both affect blood-lipid oxidation and endothelium-related markers; mixed phenols walk this circulatory antioxidant path more broadly. People with high fasting lipids and an oily diet more often notice lab markers and a lighter body after several continuous weeks.
