Teavigo

Verifiable Science

Teavigo^® is a natural, caffeine-free green tea extract providing a highly purified and refined source of epigallocatechin gallate (EGCG). Over the years, numerous studies have reported that this polyphenolic compound supports optimal cellular function and provides antioxidant protection. Multiple recent studies have suggested that EGCG supports prostate, colon, lung and bladder health.^1,2,3,4

Additionally, a clinical study reported that EGCG promoted healthy cervical tissue.⁵ An in-vitro study conducted at the Mayo Clinic in Minnesota reported that EGCG helped promote blood cell health.⁶ Research has indicated that EGCG may promote cellular health through a number of pathways, including moderating hydroxyl radical formation as well as gene expression.⁷

Furthermore, EGCG may promote healthy lipid metabolism.⁸ Investigators in one study reported that the gallate moiety on the EGCG played a particularly important role in supporting healthy apolipoprotein metabolism.^9‡

Antioxidant and anti-inflammatory effects

Much of EGCG’s claim to fame comes from its strong antioxidant capacity and potential to reduce stress and inflammation. Free radicals are highly reactive particles that can cause damage to your cells. Excessive free radical production leads to oxidative stress. As an antioxidant, EGCG protects your cells from damage associated with oxidative stress and suppresses the activity of pro-inflammatory chemicals produced in your body, such as tumor necrosis factor-alpha (TNF-alpha) (6). Stress and inflammation are linked to a variety of chronic illnesses, including cancer, diabetes, and heart disease. Thus, the anti-inflammatory and antioxidant effects of EGCG are thought to be one of the main reasons for its broad disease-preventing applications (1a).

Heart health

Research suggests that EGCG in green tea may support heart health by reducing blood pressure, cholesterol, and the accumulation of plaque in blood vessels — all major risk factors for heart disease (7, 8).

In an 8-week study in 33 people, taking 250 mg of EGCG-containing green tea extract daily resulted in a significant 4.5% reduction of LDL (bad) cholesterol (9). A separate study in 56 people found significant reductions in blood pressure, cholesterol, and inflammatory markers in those taking a daily dose of 379 mg of green tea extract over 3 months (10). Though these results are encouraging, more research is needed to better understand how EGCG in green tea may reduce heart disease risk.

Weight loss

EGCG may also promote weight loss, especially when taken alongside the caffeine naturally found in green tea. Although much of the study results on EGCG’s effect on weight are inconsistent, some long-term observational research noted that consuming about 2 cups (14.7 ounces or 434 ml) of green tea per day was associated with lower body fat and weight (11).

Additional human studies have collectively found that taking 100–460 mg of EGCG together with 80–300 mg of caffeine for at least 12 weeks is linked to significant weight loss and reduction of body fat (12).

Brain health

Early research suggests that EGCG in green tea may play a role in improving neurological cell function and preventing degenerative brain diseases.

In some studies, EGCG injections significantly improved inflammation, as well as recovery and regeneration of neural cells in mice with spinal cord injuries (13, 14).

Additionally, multiple observational studies in humans found a link between a higher intake of green tea and a reduced risk of age-related brain decline, as well as Alzheimer’s and Parkinson’s disease.
