Enhanced Winter Wellness Against Colds &amp; Flu

December 2013

By Michael Downey


The flu can mean more than symptoms such as muscle pain, nausea, and sore throat.3 On average, over 30,000 Americans die annually from influenza.1

To help prevent death from the flu’s lethal secondary infections and other complications, many people choose to receive an annual flu shot.13 However, because older adults often have a weakened immune system, the vaccine may only be effective as infrequently as 9% of the time—and only 56% of the time in the general population.16-18

However, when taken together for two weeks prior to vaccination, the amino acids L-theanine and L-cystine boost the efficacy of the flu vaccine in certain elderly subjects by enhancing the immune system itself.19 The result is enhanced protection against both the flu virus—and its deadly complications.

Remarkably, this same combination has been shown to reduce the incidence of the common cold by 58%.5
