◆ L-theanine for anxiety
Yoto et al found that taking l-theanine dosage(200 mg) + placebo (dextrin) can relieve anxiety caused by physical and mental stress in subjects. Higashiyama and other studies have shown that the intake of 200 mg of L-theanine helps to alleviate the anxiety of the normal population due to excessive attention to daily trivialities.

◆ Green tea extract for boosting immunity
L-Theanine 98% HPLC can prevent disease by improving immunity. Theanine is a precursor of the non-peptide antigen, ethylamine. When the peripheral blood γ-δT cells are exposed to the ethylamine produced by the metabolism of theanine, it will mediate the memory reaction and will secrete when it encounters the invasion of the pathogenic microorganism. γ interferon enhances human immunity and thus improves disease resistance.
