Studies show that the more often you drink tea, the more you'll reap its health benefits. Rooibos tea, hibiscus tea, and peppermint tea are the best caffeine-free teas to start your mornings with. But if you are in need of an energy boost, try choosing caffeinated teas such as white tea, jasmine tea, oolong tea, or black tea.
Green tea is a perfect in-between option. The caffeine content in green tea is higher than that of caffeine-free tea, but lower than black tea. It also contains l-theanine, the amino acid that helps counteract the jitteriness of caffeine to provide calm and focused alertness.
