I have been very pleased with this product so far. I worked immediately when I started taking it and I am interested in seeing my first A1C with the full 3 months of taking Curalin. So far I haven't had it a full month yet. I have ordered a new health watch to wear on my wrist that will take my blood pressure as well as heart rate and sleep patterns all the rest that they do. I have always had super good blood pressure and I am hoping that this product doesn't changed that, so I thought I would changed from a FitBit to this new product that added blood pressure to it's claim to fame. thank you for this product, I have taken myself off of Metformin and it still is keeping me in "the zone".
