The Task Force for Green Tea (TFGT) was surprised and more than surprised by the last studies shown that we can obtain one million, two millions per 100g of tea. These studies were done by a South African company.

Their value is contested by many experts because the range of values given is unbelievable.

 

The International Society of Antioxidants in Nutrition and Health (ISANH) and  "la Société Française des Antioxidants" (SFA) have already published on their website that ORAC is in vitro and not in vivo methods. These values are not relevant to represent the antioxidant capacity.

No relevant standardized methods to measure antioxidant capacity are currently available.
