I bought this product after hearing good things about it for managing blood sugar and intestinal problems. I can't comment on the effect on blood sugar levels as I don't have anything to check in real time, but for bloating after meals or pain after eating certain vegetables (cauliflower and broccoli, for example), this product is miraculous. I suffer from irritable bowel syndrome and from the very first day I started taking it (1x in the morning when I wake up), I could see the difference. My stomach no longer swells, it stays in its place. More effective than medication
