The C24/7 of Alliance In Motion is the best of all. It works directly by cells and boosts immune system. Even my father wo suffered from dizziness could have satisfaction by using the C24/7. It is 100% naturel, no side effects and very efficient. With its action by the cells, it is advisable for every disease. An uncle of mines in my village of origin was also suffering from diabetes. Brought to the hospital, the physicians decided to cut off his leg. Togoether with some partners by AIM Global in my country, I sent him some bottles of C24. He used it and some time after we was very well and avoided the cutting-off of his leg. Myself I used to cure my problems of knee and now for prevention.
