Reminiscent of EmergenC, the Pur Pak has a sour taste and the smell of a creamsicle. The product is full of antioxidants, vitamins and minerals, including coenzyme Q10, vitamin C, iron, potassium, glucosamine and chondroiton. Each tablet has only 15 calories and two grams of sugar and is made without artificial colors, dyes or sweeteners.
