Ener-C Sugar Free has 1000mg of Vitamin C plus the additional essential vitamins & minerals found in the regular formula, but Ener-C switched out the small amount of natural sugars with natural sweeteners. For the sugar free diet devotees! Ener-C Multivitamin Drink Mix is a healthy, caffeine-free way to support daily immunity, energy and hydration. The flavours and colours of all our formulas come from real fruit and vegetable sources, and we use a small amount of cane sugar to enable the rehydrating function of the electrolytes in our sport and multivitamin formulas. We use best-in-class mineral ascorbates as our primary source of vitamin C for superior bioavailability and absorption, along with 24 other essential vitamins and minerals.
