You’re in luck! Mother Nature offers us many options in the “natural source of caffeine” category. Various herbs fit within this group: guarana, kola nut, cha de bugre, yerba mate and, of course, green tea. When you research these items on our website, click on the Product Label tab and look for the standardized percent of caffeine in the supplement facts box. This will give you the best idea of how much caffeine is available per serving of each supplement. We also offer a variety of combination products, including our top-rated Swanson Ultra Time-Release Energy Boost, for a natural source of energy. As you know, caffeine tolerance levels vary among individuals; so pay attention to how you feel when you begin any taking natural health supplement.
