People with diabetes should monitor their blood sugar levels closely and watch for signs of hypoglycemia - or low blood sugar - when taking cinnamon tablets, notes WebMD. Signs of hypoglycemia include headaches, weakness, fatigue and shakiness. People with hypoglycemia may also experience nervousness, irritability, anxiety and a lack of coordination, notes the American Diabetes Association.

Other symptoms of low blood sugar include confusion, delirium, sweating, chills and clamminess. Unconsciousness, seizures, nightmares and nausea may occur. If a person has a rapid heartbeat, tingling or numb lips or tongue or feelings of anger, stubbornness or sadness, they may have low blood sugar levels, according to the American Diabetes Association.
