Possibly: There is some information available that by combining these two chemicals the L theanine may reduce the anxiety and vasoconstriction (temporarily making blood vessels smaller resulting in hypertension for example) associated with caffeine. My suggestion would be not to take caffeine and then you do not have to worry about the negative effects of the chemical. Good luck
