Objective: The study aimed to dictate the capability of cinnamon supplements in reducing fasting blood sugar levels (FBS mg/dl) and glycated hemoglobin (HbA1c %) for patients with diabetes mellitus II (DMII). Comparing pre and post-intervention glycemic markers with aloe vera, ginseng, and anti-diabetic medication to determine if herbal supplements are an effective complementary alternative medicine (CAM) treatment for DMII.

Methods: The range of articles gathered consisted of 175 through MEDLINE and 510 through Google Scholar; these platforms allowed access to MEDLINE and ScienceDirect articles but were reduced to 40 based on search terms such as “Cinnamomum cassia.” ” Cinnamomum verum,” “Diabetes Mellitus II,” “fasting blood sugar, and ”glycated hemoglobin.” The meta-analysis consisted of sixteen clinical trials from 2006-2022. The study designs were randomized, placebo-controlled, double-blind, and triple-blind trials.

Results:The data collection showed variability of methodology techniques such as distinctive dose ranges (500mg, 1g, 1.5g, 2g, 3g, and 6g), study lengths, anti-diabetic medication use, and cinnamon species. Post-intervention trials had sparse reduction ranges from -3mg/dl to -21.78mg/dl and A1C of

Conclusion: Cinnamon supplements can reduce FBS and A1C levels, although these results are not sustainable for a chronic patient with DMII, making it a non-reliable treatment option for DMII. More research clinical trials should be performed on cinnamon supplements to conclude more accurate, evidence-based recommendations.
