Yerba Mate

MODERATE EVIDENCESupplementLast updated

AVELOR SUMMARY

Yerba mate is the world's third most consumed caffeinated beverage (after coffee and tea), containing a unique combination of caffeine (78mg per cup), theobromine, and chlorogenic acids. Our research shows genuine evidence for fat oxidation enhancement (24% increase during exercise) and modest cholesterol/blood sugar reduction. The MAJOR safety concern: heavy consumption (>1L/day of very hot mate) is classified by IARC as "probably carcinogenic" — but this is largely attributed to THERMAL INJURY from drinking at >65°C rather than the compounds themselves. The esophageal cancer association is specific to South American mate-drinking culture (very hot, through metal bombilla straw).

WHAT IT DOES

Yerba mate contains: (1) caffeine (1-1.5% by weight) — adenosine receptor antagonism, catecholamine release, thermogenesis; (2) theobromine — mild bronchodilator and mood elevator (same compound as in chocolate); (3) chlorogenic acids — inhibit hepatic glucose-6-phosphatase (reduce glucose output) and intestinal α-glucosidase (slow sugar absorption); (4) saponins (matesaponins) — inhibit pancreatic lipase (reduce fat absorption) and have anti-inflammatory/antimicrobial activity; (5) polyphenols — antioxidant and NF-κB inhibition. The fat oxidation enhancement during exercise is likely synergistic between caffeine (catecholamine-driven lipolysis) and chlorogenic acid (fatty acid oxidation enhancement).

OPTIMAL DOSAGE

Look for: Ilex paraguariensis; green (unsmoked) mate preferred; caffeine content declared; cold-brew option for safety
Avoid: Smoked mate (contains polycyclic aromatic hydrocarbons — PAHs); very hot consumption (>65°C — esophageal cancer); excessive daily consumption (>1L)
Minimum effective dose: 1g extract or 1 cup tea
Third-party tested brands: Guayaki (organic), EGO (yerba mate extract), NOW Foods
