If you are talking about the CBD gummies they do nothing for blood sugar but might work well if you have a bit of diabetic neuropathy
A number of smaller studies were done to see if CBD would help blood sugar and the answer was NO
But if it reduces a bit of pain or alleviates some stress then that will put downward pressure on blood sugar - so maybe in a round about way IF you have some other condition the CBD helps with that is causing a blood sugar rise
