AMP may not be as well known as the other beverages on this list, but the drink makes the cut due to its taste. AMP Energy Boost has a sweet, carbonated citrus flavor and, unlike many other energy drinks, contains real orange juice (even if it is from concentrate). Distributed by Pepsi, AMP began life as the energy drink version of Mountain Dew. Since then, the beverage has gone through various incarnations. They now offer AMP Energy Boost, AMP Energy Focus (with l-theanine and choline), and AMP Energy Active (with electrolytes). All three contain B-vitamins, caffeine, ginseng, guarana and taurine, which means they basically contain the same ingredients as the other drinks on this list. But if you’ve tried the other brands and did not vibe with their chemical taste, give AMP Energy Boost a try. All of AMP’s drinks are competitively priced; a 16-ounce can of AMP costs less than an eight-ounce can of Red Bull — another plus!
