It hurt my stomach. I think my doctor thought this was my problem, but I didnt have bloating or gas, so when I took it, my stomach hurt. For people who do have those issues, Im sure the strength of this would help. But I just had constipation and it fidnot help for that. Good old magnesium , which she said I didnt need , was my magic bullet for constipation. 600mg a day. Since the country is deficient in magnesium #2 most deficient thing....I would start there. Magnesium glicinate worked awesome and brought down my glucose!!
