I've tried other Function Light Weight Drinks before, but I saw the Peach Mango flavor in the grocery store today and decided to give it a go, especially because I like all things peachy. Plus, on the front of the package is the following snippet: Ignite your body's natural metabolism and calorie burn ability with a formula featuring antioxidant catechins EGCG and gymnema, plus polygonum cuspidatum (a plant rich in resveratrol). At just 5 calories per serving, it sounded good to me! One bottle was $1.99, but it was a price I was willing to pay.
How does it taste? Pretty good. All Function waters have a strange lingering taste after the regular flavor hits - it's not bad, just different. The peach mango flavor was prominent but not in-your-face, and I gladly gulped down the bottle.
What's in this Function drink? A mix of water, apple juice concentrate, citric acid, natural flavor (natural fruit extracts), green tea catechins, calcium carbonate, gum arabic, acesulfame potassium, natural caffeine, gymnema sylvestre leaf extract, sucralose, ester gum, beta-Apo-8' carotenal, resveratrol (polygonum cuspidatum) root extract, and cholecalciferol (vitamin D3). That's a lot of ingredients, but most are the added nutrients.
All of those together combine to give each 8-ounce serving 5 calories, no fat, 1 gram of sugar, 50% of the RDA for vitamin D, 5% of the RDA for calcium, and a proprietary blend of caffeine, EGCG, gymnema sylvestre leaf extract, and resveratrol leaf extract.
Like I said, the taste was just okay. At the price, I'm not sure I'll be buying this regularly, but I enjoyed it and will probably purchase it again sometime in the future.
