Green Tea Antioxidant Supplement May Help With Weight Management
A recent study suggests that supplements containing the antioxidant epigallocatechin-3-gallate (EGCG) from green tea may help increase energy expenditure, metabolic rates, and aid with weight management.
The researchers examined data from eight randomized trials for their analysis. The trials included a total of 268 participants and used doses of EGCG ranging from 300 to 800 milligrams daily. The studies lasted from two days to 12 weeks.
After examining the data, the researchers found that EGCG supplementation was associated with moderate reductions in respiratory quotient (the ratio of carbon dioxide produced to oxygen consumed while food is being metabolized) and higher energy expenditure. There was not, however, any observed changes in fat breakdown.
Researchers from Taiyo Kagaku Co. Ltd., the University of Mie, and Aichi Medical University in Japan conducted the study. It was published online ahead of print on November 2, 2016, in The Journal of Nutritional Biochemistry.
EGCG is one of the four main types of powerful antioxidants in tea. Previous studies suggest that EGCG may help balance blood sugar levels and may be linked with a decrease in the risk of neurodegenerative diseases.
