6 months ago, when I started talking Gluctose, my A1C was 6.5. As of yesterday, my latest A1C is 6.4. I guess if I'm honest, I'm a little disappointed. Before I purchased Gluctose, I read dozens of reviews. Each one more glowing, than the last. I'm not going to say anything negative about your product, because after all, my A1C did go down. I just have to decide, whether the cost is worth it. As a senior citizen, on a fixed income, I have to say, no.
