Natural Supplements question

Has anyone used PetAlive GlucoseEnsure or Only Natural Pets Glucose Wellness tablets? At www.onlynaturalpets.com, they sell these supplements for diabetic animals. Per the reviews, the GlucoseEnsure sounds like it might help. I can't seem to get my cat regulated and am thinking of ordering some and seeing what results I get. Just wondering if anyone else has tried or heard anything.

 

There are a lot of things in there that might be good for humans but not necessarily for cats, including cinnamon which can be toxic if cinnamon oil, and chromium and vanadium. I'd be very leary...
