Patented Tea Extract Dietary Supplement Non-GMO An increasing number of scientists recognize the critical need to protect the arterial wall against low-density lipoprotein (LDL) oxidation and inflammatory insults. Research has shown that unique compounds present in black tea called theaflavins and thearubigins can have multiple applications for arterial health. Theaflavin Standardized Extract contains a number of beneficial flavonoids found naturally in tea leaves that help support levels of cholesterol that are already within the normal range. Theaflavins have been shown in human studies to protect against LDL oxidation and favorably affect endothelial function, thus helping to maintain healthy circulation.

In addition, theaflavins have been found to be helpful in regulating key inflammatory mediators in the body, thus helping to preserve cellular integrity.
