For years the market for fast-acting effervescent vitamin-C drink mixes has been dominated by one familiar brand: Emergen-C. Now, Swanson Ultra® is changing the game with our new 1,000 mg Energy C with Electrolytes featuring advanced Transport-C PLUS® and none of the sugar or artificial ingredients. With Energy C you get the same energizing nutrition, improved by science, at a low Swanson price. Transport-C PLUS combines ascorbic acid with alpha lipoic acid to reduce the loss of active vitamin C caused by oxidation as it enters the bloodstream. Alpha lipoic acid, itself a powerful antioxidant, actually regenerates oxidized vitamin C to keep it working over a longer period of time. The Transport-C PLUS complex is designed to enhance antioxidant activity, prolong vitamin C's benefits and facilitate more rapid, complete cellular uptake. With a full profile of electrolytes and supporting nutrients—including 200 mg of potassium—plus all-natural flavors and sugar-free stevia for sweetness, Energy C is a high-value alternative to other energizing vitamin C drink mixes.
