Combining Green Tea and L-Theanine dramatically cuts down on flu infections in healthcare workers

May 17, 2011

197 healthcare workers were split into two groups in a 5 month study carried out from November 9, 2009 to April 8, 2010. 98 were supplemented with 378mg of Green Tea Catechins and 210mg of L-Theanine daily and 99 received inactive placebo. Only 4% of those on Green Tea/L-Theanine developed the flu but 13% on placebo developed the flu. The supplement cut the risk of developing the flu by 75% in healthcare workers; people who work shifts, have a high stress career, and are exposed to infected patients. The length of infection was also much shorter in those on supplementation if they did get sick. The study is published in the February 2011 issue of the journal BMC Complementary and Alternative Medicine.
