How much L-theanine is in green tea?
Green tea contained the highest amount of theanine (6.56 mg/g) and since the caffeine content was comparable with the values of the previous samples (16.28 mg/g in average), the caffeine/theanine ratio was remarkably lower (2.79).
Does theanine cross the blood brain barrier?
Theanine crosses the blood–brain barrier and may be taken up by the cells via a sodium-coupled active transport process. No guidelines about effective dosage ranges have been established. Theanine supplements are usually well tolerated and no adverse effects have been reported thus far.
