Green Tea Extract plus L-Theanine help reduce blood pressure and cholesterol within just three-weeks

November 21, 2008

Researchers from the University of Florida, Brigham and Women’s Hospital and Harvard Medical School, and the Nutritional Science Research Institute, Boston, supplemented 52 healthy men and 72 healthy women with a daily supplement of 200mg of Green Tea Extract supplying 160 mg of green tea polyphenols and 90mg of EGCG, along with 100mg of L-Theanine (Suntheanine) or placebo for three weeks.
At the end of the supplementation period the researchers found that total cholesterol had dropped by 10 mg/dL and LDL-cholesterol dropped by 9 mg/dL. Systolic blood pressure dropped by 5 mmHg and diastolic blood pressure dropped 4 mmHg following daily supplementation with Green Tea Extract and L-Theanine.

The level of malondialdehyde (a marker of oxidative stress) dropped 12% and amyloid-alpha (a marker of chronic inflammation) dropped 42% respectively. The study is published online ahead of print, in the October 9th 2008 issue of the journal Nutrition.
