Yerba mate quickens the mind and increases alertness and acuity. Yerba mate also provides sustained-release energy due to its complex combination of xanthine alkaloids, (including caffeine, theobromine, and theophylline) and nutritional support (including B vitamins and chromium). The average cup of mate made from brewed tea bags contains around 40 mg of caffeine, roughly 1/3 of what coffee delivers.
Many of the innovative new yerba mate beverages on the market today contain higher levels of caffeine that are comparable to coffee. These products include mate lattes and bottled yerba mate drinks. Also, levels comparable to coffee can be achieved if desired by brewing 12 or more grams of loose yerba mate. Clinical studies have shown that caffeine-sensitive individuals generally have very positive results with mate and don’t experience the hard side effects (jitters, stomach discomfort, headache) commonly associated with other sources of caffeine.
