These effects have been observed in both animal and human studies, particularly with Ceylon cinnamon extracts.
Ceylon cinnamon is generally preferred for blood sugar support because it contains very low levels of coumarin—a compound in Cassia cinnamon that may be harmful in large amounts. As such Ceylon cinnamon is considered g it a safer and a more effective option for regular use. Our study found that C. zeylanicum extract is safe for consumption, as it did not cause any significant changes in liver function (AST and ALT levels) or kidney function (eGFR)
