An increasing number of scientists recognize the need to help support the arterial wall against low-density lipoprotein (LDL) oxidation to support arterial health. Research has shown that compounds present in black tea called theaflavins and thearubigins can have multiple applications for supporting arterial health. Theaflavin Standardized Extract contains a number of beneficial flavonoids found in tea leaves.

Scientists have found that black tea flavonoids, including theaflavins and thearubigins, can help scavenge free radicals, maintain oxidation and anti-oxidation pathways, and help inhibit oxidative stress to molecules throughout the body. ^1-3 In particular, theaflavins and thearubigins have been shown to support lipids against oxidative stress and maintain already-healthy lipid and glucose levels. ^4,5

Black tea and its flavonoids have been found in human studies to help support against LDL-cholesterol oxidation and favorably promote endothelial function, thus helping to maintain healthy circulation. ^6-8 In addition, black tea extracts have been found to support normal cell division, modulate an important enzyme involved in gene expression, and help inhibit inflammation to support cellular health.^3,9-11
