Quick Take

A caffeinated tea for alertness; modest evidence for metabolism and lipids, but safety concerns if consumed very hot.

Yerba mate is a traditional South American infusion made from dried leaves of Ilex paraguariensis. It contains caffeine, theobromine, and polyphenols such as chlorogenic acid and rutin, which are not found in meaningful amounts in common foods outside the infusion. Caffeine blocks adenosine receptors to increase alertness, while polyphenols may influence lipid and glucose metabolism via AMPK activation. Trials suggest acute improvements in alertness, modest reductions in body fat over 8–12 weeks, and lower LDL cholesterol in hyperlipidemic adults. Best suited for adults seeking a moderate caff

How It Works

Caffeine and theobromine antagonize adenosine receptors, increasing norepinephrine release and reducing perceived fatigue. Polyphenols such as chlorogenic acid and rutin may inhibit adipogenesis and activate AMP-activated protein kinase (AMPK), potentially influencing lipid storage and glucose uptake. Saponins in the leaf may also modulate bile acid absorption, contributing to cholesterol changes.
