Origin & History
Gallocatechins, including epigallocatechin (EGC) and epigallocatechin gallate (EGCG), are potent polyphenolic compounds abundantly found in *Camellia sinensis* (green tea) leaves. Green tea is minimally processed to preserve these bioactive compounds, making it a globally recognized source of functional nutrition.
“Green tea (*Camellia sinensis*) has a rich history spanning over 4,000 years, originating in China and becoming central to East Asian cultures. Traditionally revered for its medicinal properties, including digestive support and promoting mental clarity, its gallocatechins are now globally recognized for their profound wellness benefits.”Traditional Medicine
Scientific Research
Extensive research, including *in vitro*, animal, and human clinical trials, supports the broad health benefits of green tea gallocatechins, particularly EGCG. Studies demonstrate their roles in antioxidant defense, cardiovascular protection, metabolic support, and neuroprotection, with ongoing research exploring anti-cancer properties.

Frequently Asked Questions
What are gallocatechins?
Gallocatechins are a class of powerful antioxidant compounds called polyphenols found abundantly in green tea. The most famous and well-researched of these is Epigallocatechin gallate (EGCG), which is responsible for many of green tea's health benefits.
Is it better to get EGCG from tea or supplements?
Brewed green tea provides a full spectrum of compounds, including L-theanine, which can balance caffeine's effects. Supplements offer a concentrated, standardized dose of EGCG, which is more practical for achieving therapeutic levels studied in clinical trials.
Are there side effects of green tea extract?
At standard doses, it is generally safe. However, high doses can cause gastrointestinal upset or, in rare cases, elevate liver enzymes. Due to its caffeine content, some may experience jitteriness or sleep disturbances.
