Yerba mate (Ilex paraguariensis) is widely used as a natural stimulant to combat fatigue and increase energy, a practice rooted in both traditional use and supported by scientific evidence. The primary reason for its energizing effect is its caffeine content. Yerba mate generally contains 30–50 mg of caffeine per 8-ounce serving, which is comparable to the amount found in tea but less than coffee. Caffeine is a well-studied central nervous system stimulant known to reduce fatigue, improve alertness, and enhance cognitive performance.

Several studies have investigated yerba mate's effects on energy and mental performance. For instance, research published in the journal Nutrition & Metabolism (2008) found that yerba mate consumption led to increased energy expenditure and improved exercise performance, likely due to its combined caffeine and antioxidant profile. Additionally, a review published in Food and Chemical Toxicology (2013) noted that the beverage's stimulating effects are primarily attributed to caffeine, theobromine, and other xanthines present in the leaves.

While much of the evidence for yerba mate's energizing effects comes from its caffeine content (a mechanism well-supported in the scientific literature), some studies suggest that other compounds in yerba mate may also play a role in mood and energy enhancement. In summary, there is scientific validation for the use of yerba mate to address lack of energy, though its effects are similar to other caffeinated beverages, and more research is needed to determine if it offers unique benefits beyond those of caffeine alone.
