For those who want a jolt of caffeine along with your vitamins, spark definitely does that. However, it does contain a big more caffeine is you are only a 1 cup coffee drinker like me. Check the ingredients! Also, while it doesn't have pure sugar, it has an artificial sweetener (that's why it tastes so great!), which you should be mindful of especially if you're drinking more than one spark per day. If you're serious about nutrition, you should definitely not take the product for granted that it is healthy. It, at its core, is an energy drink.
