Smoothies can be as healthy as you want them to be. And now there's a simple hack to create an even more nutritious shake: Add a plant or fruit powder. Found on juice-bar menus and in health-food stores, these extracts are made from foods with intense concentrations of nutrients. "Add a scoop of one and you elevate a normal smoothie to superfood status without spending a fortune on exotic, hard-to-find ingredients," says New York City nutritionist Lisa Hayim. "And they pack in nutrients and minerals that you may not otherwise be getting." You can add any powder to any kind of smoothie, but the health perks depend on which extract you choose. We help you game them below. These benefits aren't new age voodoo; they're all backed by rigorous research. Note, though, that doubling or tripling up on powders in one smoothie would be not only expensive (the extracts can run as high as $25 for 3.5 ounces) but also unwise — your body can absorb only so many nutrients. And because a powder's benefits come with regular consumption, it's best to pick a lane and stay in it.
