No more a skeptic after I tried my first bottle. I am a prediabetic with my blood glucose inching up in the last several years. My last test in May was 130 and so I decided to give Curalin a try. Previously I had tried cinnamon tablets, Beriberine tablets all of which had no impact. After six weeks of taking Curalin I did another blood test and to my amazement my blood glucose was 101. This beat my wildest expectations. I have bought my second bottle and I am now taking 3 capsules a day and will test myself again in a month to see if that is the right dosage for me. Hope my experience helps.
