Active Ingredients and How it Works

From Isatori’s website: “Each serving of Curvelle gently delivers a combination of natural, proven ingredients—a proprietary mix of raspberry, elderberry, cinnamon extract, natural caffeine, and green tea. Rich in antioxidants and anthocyanins, these familiar ingredients have been clinically shown to fight off the oxidative stress of aging, a less-than-perfect diet, and pollution to reveal radiant, glowing skin and improve your overall health. What’s more, they’re well documented to decrease cravings for sugar and rapidly burn off excess calories to help reveal your beautiful natural curves.”

• Green Tea extract: a diuretic, antioxidant, and increases metabolism
• Cinnamon extract: controls blood sugar and appetite
• Razberi-K (raspberry ketone): has thermogenic properties, and inhibits absorption of dietary fat
• Elderberry extract: an antioxidant, diuretic, and increases carbohydrate metabolism
• Caffeine: a diuretic, and boosts metabolism

Scientific Evidence

Most of these ingredients have no credible human scientific evidence that supports Curvelle’s claims. There have been numerous animal studies, but studies on humans have not yet reproduced these results, with the exception of green tea and cinnamon extract. In addition, we do not know how much of each of these essential ingredients is in the Curvelle formula because it is protected by a proprietary formula that prevents the actual amount of each ingredient to be known. Furthermore, even if these ingredients do achieve these effects, what is the likelihood that you’re actually going to lose weight with this product?

Consumer Feedback

“I have been taking Curvelle for about a month and have noticed a decrease in weight. I've dropped about one clothing size. It's great and it doesn't interfere with sleep. It keeps your appetite down and keeps the weight off. I love it. I'm going to keep taking it and it's natural.
