A: I would definitely check with your doctor on this, but myo-inositol is actually used for balancing blood sugar, and it has been used in PCOS, and type II diabetes. It's been used in gestational diabetes as well to help normalize blood sugar.
I imagine the warnings are for those who have diabetes and are already taking hypoglycemic medications that lower their blood sugar. For those people taking something else that could lower their blood sugar further could result in extremely low levels of blood sugar. If you're taking any medications, check with your doctor, but myo-inositol is potentially helpful for stabilizing blood sugar. Therefore, it can be helpful for people with insulin resistance and for improving glycemic control even in pre-diabetes. However, be sure to check with your doctor.
