“Stress aggravates allergies, so what you really want to do is drink a lot of green tea and also look for foods and drinks that have Suntheanine as an ingredient,” said Dr. Jonny Bowden during his Good Day Sacramento interview. “Suntheanine actually gives you calm, clear focus … and is wonderful for reducing the stress component of allergies,” Bowden explained. He added that Suntheanine, a pure form of L-theanine produced by a patented enzymatic process, is emerging as an ingredient in some energy drinks. “[They are] lowering the caffeine and upping the Suntheanine so you get the calm, clear focus without all the jitters.”
