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) · Highly β1-selective adrenergic antagonist. Greater selectivity than metoprolol or atenolol. (1) · Primary alkaloid is (S)-(-)-cathinone, a phenylpropanolamine close kin to amphetamine. Releases dopamine and norepinephrine. Also contains cathine (=norpseudoephedrine) and norephedrine. (1) · The d-enantiomer is a highly β1-selective antagonist; the l-enantiomer triggers endothelial nitric-oxide–mediated vasodilation. Unique among beta blockers for this NO mechanism. (1) · '"`UNIQ--vote-0000124C-QINU`"' The 400 mg/d dose for migraine prophylaxis is supported by randomized trials (Schoenen 1998) and remains a low-risk evidence-based supplement option.
