100% Naturally Sweetened & Flavored

100% Naturally Sweetened & Flavored
While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[1][2][3][4][5][6]
That’s why we use the natural sweeteners stevia and erythritol instead. Studies show that they’re not only safe but can also confer several health benefits, including better insulin sensitivity, a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[7][8][9][10]
