I love this stuff! It's a blend of antioxidants, vitamins, minerals and nutrients that help to support a healthy metabolic function, boost your immune system and give you a burst of non-caffeinated energy. It's better than other Vitamin C supplements because it also has 32 mineral complexes and B Vitamins. Because this isn't medicine, I feel confident giving it to my kids and taking it multiple times a day when we feel colds coming on. We take it daily instead of multi-vitamins during winter to fight off sickness. I think it works! My family rarely gets sick. But when we do, we take multiple doses to shorten the duration and lessen the severity of our cold symptoms. A powerful boost of vitamins and minerals can only help you. If anything, your body will just eliminate the excess, but it can't hurt you.
