Supports bladder, kidney & urinary tract health

Andrew Lessman's EFFICIENT C + CRANBERRY BENEFITS reinvents the Vitamin C drink. It provides superior forms and amounts of all key nutrients and its delicious, natural flavor comes with NO calories, sugar or carbohydrates. Each serving provides an ideal 500 mg of Non-Acidic Vitamin C for optimum absorption without stomach upset, along with 500mg of our Cranberry Benefits for unparalleled support of the bladder, kidney and urinary tract. We also include our unique blend of all essential B-Complex vitamins to support virtually all body processes, including energy production and fat metabolism. Plus, our B12 is present as natural methylcobalamin, which avoids the use of cyanocobalamin, a synthetic form of B12 that exposes us to cyanide. We also use naturally active 5-MTHF (5-methyltetrahydrofolate), instead of folic acid, since so many of us cannot metabolize ordinary folic acid. Of course, we also provide essential Vitamin D3. The beverage's rich color does not result from artificial colors, but from an anthocyanin-rich extract of Black Currant providing extensive immune and eye health benefits. We also avoid undesirable carbonation and instead you can enjoy the pure, natural flavor of Efficient C. In short,Efficient C + Cranberry Benefits is a delicious new take on Vitamin C drinks without anyof the calories, sugars, carbs, artificial sweeteners or other undesirable additives of typical beverages. Plus, it also provides all the bladder and urinary tract support benefits of our popular Cranberry Benefits.
