Enviga is a new drink that first became available in January 2007 from Nestlé. The drink is a green tea, caffeinated and carbonated drink that claims to increase your metabolism and increase your fat-burning capabilities. Nestlé claims that per can consumed you can lose up to 20 - 30 calories. Contrary to most bottled green teas, which are high in sugar (and therefore calories), Enviga is actually calorie-negative. The active ingredients in Enviga are EGCG, a naturally occurring plant extract found in tea plants, and caffeine, with 100 mg per serving (about the same as a cup of coffee).
Enviga is available in three flavors: green tea, peach, berry. Each can also contains 20% of your daily calcium intake. While the drink really contains 5 calories, according to Nestlé, the science of thermogenesis accounts for the net-negative calorie count.
Look for Enviga in 6-can and 12-can multi-packs, with individual cans retailing for between $1.29 and $1.49.
