Although there definitely is a time and a place for Red Bull, I generally try to get my energy boost from more natural, less syrupy-sweet sources. One of the most naturally energizing drinks around, the caffeine-containing tea yerba mate offers 11 antioxidants, 24 vitamins and minerals, and 15 amino acids.

My most beloved purveyor of the rainforest-derived powerhouse, Sebastopol, California-based Guayaki is rolling out a new line of bottled teas blended with medicinal herbs. That includes Pure Mind (with circulation-stimulating, brain boosting ginkgo biloba and the stress-relieving ayurvedic herb tulsi) and Pure Passion (with the antidepressant damiana and nerve-calming catuaba, both of which act as aphrodisiacs), but my favorite flavor is the Pure Endurance. Made with ginseng (known to build up your resistance to stress) and Himalayan crystal salt (to deliver electrolytes), the tangerine-infused drink gives you good buzz without that scary shaky feeling or the inevitable crash a little while later.

Plus, by gulping down Guayaki you’re helping to save the planet: Drinking two servings of the product per day helps protect approximately one acre of rainforest every year, according to the company’s president.
