Herb
Yerba mate
SaveA caffeinated South American leaf beverage used for energy, focus, and appetite support.
Quick verdict
A practical tea-like stimulant with added polyphenols, though it should be treated like a caffeine source, not a free ride.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Yerba mate provides caffeine, theobromine, and polyphenols and has some support for energy expenditure and attention. Chronic very hot mate intake has confounded epidemiology because heat itself may drive risk.
Benefits
- Improves alertness and energy
- Provides polyphenols beyond simple caffeine
- May modestly support appetite control
Dosage notes
Usually consumed as brewed tea or loose-leaf infusion, with dose determined largely by caffeine tolerance.
Side effects
- Insomnia
- Anxiety
- Palpitations
Who should be cautious
Excess use can cause anxiety, palpitations, and insomnia. Very hot beverages should be avoided.
What this page cannot tell you
Its benefits are real but overlap heavily with other caffeinated beverages, so effect size depends on the user and preparation.
