Special qualities of TeaVitaL
1. Standardized on the basis of scientific specifications
According to the American National Cancer Institute (NCI) daily consumption of 1200 ml of green tea containing 710 mcg/ml EGCG is equivalent to 1,5 times the lowest effective anticancer dose in a 70-kg person.(1)
TeaVitaL is guaranteed to meet 710 mcg EGCG per ml tea. The tea leaves are certified to contain at least 7,1% EGCG in dry weight to comply with this specification. In contrast, green teas typically found in many grocery stores average antioxidant contents in the range of 2-4% EGCG.

Each batch of TeaVitaL's packaged tea leaves is sent to certified laboratories for independent quality testing before release to the end consumers.
2. Organic origin
Tea leaves are harvested from tea plantations that do not use pesticides and that are far away from industrial regions to avoid heavy metal contamination.
3. Oxygen-exclusion processing and packaging
Fresh tea leaves plucked are quickly heated to above 70°C to prevent enzymatic oxidation of EGCG. Dried leaves are packed with oxygen-exclusion technology for maximum quality preservation.
