Does Supplementation With Green Tea Extract Improve Insulin Resistance In Obese Type 2 Diabetics? A Randomized, Double-blind, And Placebo-controlled Clinical Trial

この研究の注釈:

EGCG at a dose of 865mg showed improvements in metabolic parameters (insulin, insulin sensitivity, HbA1c, waist circumference) when measured between groups, but not overall.

Indicative of different effects in different persons.


Effects Of Dietary Supplementation With The Green Tea Polyphenol Epigallocatechin-3-gallate On Insulin Resistance And Associated Metabolic Risk Factors: Randomized Controlled Trial

この研究の注釈:

Overweight or obese men were given placebo (lactose at 400mg) or EGCG at 400mg for a period of 8 weeks.

No effects noted on any insulin sensitivity or blood glucose parameter relative to control, although a significant reduction in diastolic blood pressure (-2.68mmHg) was noted.

Body fat and lipid markers trended towards significance, but did not reach.


Green Tea Extract Ingestion, Fat Oxidation, And Glucose Tolerance In Healthy Humans

この研究の注釈:

Green tea extract was able to _acutely_ reduce insulin secretion and improve insulin sensitivity (13%) when supplemented at a dose of 890mg total catechins, giving 366mg EGCG; study conducted in otherwise healthy young men.

Fat oxidation rates were also increased by 17%.
