The AUC70 of L-theanine in plasma increased dose dependently
from 50 mg [35.5 6 10.7 mmol/L 3 h; n = 3] to 100 mg
[65.4 6 17.6 mmol/L 3 h; n = 3] and to 200 mg L-theanine
[1736 23.0 mmol/L3 h; n = 3], because the AUC70 after the intake
of each dose differed from the others (P < 0.05) (Supplemental
Fig. 1)..
