Yerba Mate

Ilex paraguariensis

Ilex paraguariensis (South American Holly)Caffeine + Theobromine + Theophylline TeaEnergy / Cognitive StimulantDietary Supplement / Tea

Yerba Mate (Ilex paraguariensis) is a South American holly leaf traditionally consumed as tea (mate) in Argentina, Uruguay, Paraguay, and southern Brazil. Contains caffeine, theobromine, and theophylline (the three major xanthine alkaloids), plus chlorogenic acid, saponins, and polyphenols. Effects similar to but distinct from coffee - smoother stimulation with less anxiety/jitteriness.

How it works

Yerba Mate's effects come from its xanthine alkaloid profile:

Caffeine

Adenosine A1/A2A antagonist - standard wakefulness mechanism. Yerba Mate contains 30-50mg/cup vs coffee's 95mg/cup - milder stimulation.

Theobromine

Cocoa's main xanthine. Mild vasodilator and bronchodilator. Smoother, longer-lasting stimulation than caffeine alone.

Theophylline

Tea xanthine. Bronchodilator and vasodilator.

Combined Profile

The three-xanthine combination produces smoother, longer-lasting stimulation with less anxiety/jitteriness than equivalent coffee dose.

Chlorogenic Acid

Modest blood sugar regulation and cardiovascular benefits.

Polyphenols

Antioxidant effects.
