During a failed attempt to discover gravity, Sir Isaac Newton fell face-first into a snow bank while carrying a heap of delicious fruit—inadvertently discovering the health benefits of mixing squashed nutritious food with subarctic cold. Today’s Groupon lets you replicate Newton's experiment under controlled conditions: for $5, you get three vitamin-packed, 20-ounce smoothies off the menu at Smoothie King (an up to $15 value before tax, depending on the smoothies). This offer is valid at locations in Highland, Collierville, and Cordova. You must redeem at least two of your smoothies on the first visit, at which time you may take a voucher for the third. Additional charges may apply for enhancers.

Outside of swimming laps in chocolate syrup, smoothies at Smoothie King are the tastiest way to improve your health. Smoothie King smoothies combine fresh fruit, natural juices, and special nutritional enhancers into more than 90 flavors (you can customize, add, and subtract the extras), all of which focus on achieving one of seven nutritional goals. Try an antioxidant-rich Pomegranate Punch with pomegranate, bananas, blueberries, apple juice, soy protein, and Turbinado sweetener to stay healthy. Weight-conscious en-smuthiasts can trim down and float away with the Celestial Cherry High, packed with bananas, black cherry, papaya, Turbinado, and honey, and unpacked with fat. You can also customize any smoothie by adding enhancers or “make it skinny” by cutting out the honey and Turbinado.

All that choice stems from Smoothie King founders, Steve and Cindy Kuhnau, and their decades of experience. Seeking a delicious way to alleviate his allergies and low blood sugar in the late 1960s, the male Kuhnau tried blending fruit, nutrients, and proteins at home, creating a healthy smoothie. In 1973, he opened his first health store with the first official smoothie of Smoothie King. Smoothie King remains committed to tasty health solutions, complementing its smoothie selection with snacks and supplements along with advice for good health. You can buy multiple Groupons as gifts, so treat your friends to some tasty, frozen medicine and start an epidemic of feelin’ good.
