The polyphenols in green tea are potent antioxidants shown to be highly beneficial to the heart.
What is Green Tea?By "tea," we mean the leaf of the plant, Camellia sinensis. There are really only three categories of teas: green, oolong, and black.
Each of these is the leaf of Camellia sinensis and differs only in duration of fermentation: "black" is fully fermented, "oolong" is partially fermented, and "green" is not fermented at all, only steamed.
Health Benefits Of Green Tea ExtractControlled studies on green tea extract have yielded impressive results, identifying the polyphenol (-)-epigallocatechin gallate (EGCG) as the responsible component. EGCG is an important nutrient that may support immune system function, skin health, joint comfort, intestinal health, liver function, weight loss, dental care and respiratory health. It offers antioxidant support against the free radicals that attack collagen (the skin's structural protein) and decreases the activity of the enzyme that breaks down collagen to help keep skin firm and healthy

Parts Used & Where Grown
All teas (green, black, and oolong) are derived from the same plant, Camellia sinensis. The difference is in how the plucked leaves are prepared. Green tea, unlike black and oolong tea, is not fermented, so the active constituents remain unaltered in the herb. The leaves of the tea plant are used both as a social and a medicinal beverage.
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
