Green Tea Extract and Hypertension

A Polish study published in the June issue of Nutrition Research found that supplementation with a green tea extract can lead to significant reductions in C-reactive protein (CRP), an inflammatory marker, as well as decreases in systolic and diastolic blood pressure in obese people with hypertension. Green teach contains several polyphenols, one of which is epigallocatechin gallate (EGCG). This study used a daily dose of green tea extract of 379 mg, which provided 208 mg of EGCG. The subjects consumed either the extract or a placebo for three months. AFter three month those consuming the green tea extract saw a drop in their blood pressure of 4.9 (systolic) and 4.7 (diastolic). CRP dropped by 0.9 mg/L in the green tea extract group, but increased by 0.11 mg/L in the placebo group. Significant improvements in LDL and HDL cholesterol levels were also noted in the green tea extract group.
