Is stress or fatigue making it hard to focus and recall details? The amino acid l-theanine in green tea clears the fog and resharpens your brain. “It stimulates the production of the alpha brain waves, a state achieved by meditation where you become deeply relaxed, yet mentally alert,” explains Jacob Teitelbaum M.D., author of From Fatigued to Fantastic.
Bonus: Downing two or more cups of green tea daily makes you half as likely to get mentally fuzzy as you age than folks who sip three or fewer cups per week, suggests a study in the American Journal of Clinical Nutrition.
