Cinnamon capsules won't hurt you but don't rely on them really doing much to move your blood sugar more than 25 - 50 points at best!! If Cinnamon were really effective, drug companies wouldn't still be spending 100's of millions of dollars on diabetes drug research! They'd all be selling cinnamon!!!
If you take the Cinnamon and it pulls your Hubby from where he is to under 100, well thats super! If they don't really move him at all, well, chalk it up to a good old fashioned try, but don't expect to eliminate one of his meds with it!
