* *ADVISORY* *L-theanine should be used only under a doctor’s supervision if you are taking drugs for chemotherapy because it increases the activity of some cancer chemotherapeutic agents. Do not take L-theanine with cholesterol lowering medications.
DOSAGE:200 to 400 mg once or twice daily. (1200 maximum a day).
CONCLUSION:We conclude that L-theanine is a safe and effective way to help treat anxiety and improve concentration. We prefer drinking the tea leaves naturally to taking the supplement. Remember to include it in your list of supplements when you visit your doctor and other health care providers.
