I have been taking the Curalin about four weeks. When I first purchased It I was very doubtful that it would work. I thought that it was somewhat expensive and if it didn’t work I would ask for my money back. I take my blood sugar check every morning at six and chart the results. Much to my surprise within a week my numbers had dropped about twenty points on average and even my blood pressure had dropped. I just had a physical exam last week and the A1C was down significantly. Last fall it was at a 6.7 level. In February it was 6.5 and last week it was at 6.3. I am overjoyed that this can work this well. So I have now stopped taking the 500mg of Metformin In the morning But still taking the same dose at night. I am very happy with the product and will continue as long as my numbers are at that level of performance. John Noland
