mechanism:
Caffeine + theophylline + L-theanine. L-theanine (an amino acid unique to tea) modulates glutamate and produces an 'alpha-wave' calming overlay on caffeine's stimulation, hence tea's reputation as a 'cleaner' stimulant than coffee. (1) ·
Caffeine is a non-selective adenosine A1/A2A receptor antagonist; also weak PDE inhibition. Beans contain theobromine (3,7-DMX) and theophylline (1,3-DMX) in smaller amounts. (1) ·
