Why is there additional Vitamin C in Vináli?

Medical studies have shown that there is a synergistic effect from consuming vitamin C and grape seed extract together. They both enhance each other's benefits. This means that one plus one is not two, but instead is eight or ten. Many companies use grape seed extract without any other nutrients in their products, which decreases their effectiveness. ARIIX uses the highest quality grape seed extract available in the marketplace today, AND combines it with vitamin C to make it even more potent.
