Q: Do cinnamon supplements improve glycemic control in adults with T2DM? Evidence-based answer: the answer isn't clear. Cinnamon supplements for adults with type 2 diabetes haven't been shown to decrease hemoglobin A1C (strength of recommendation [SOR]: C, multiple systematic reviews of disease-oriented outcomes). Cinnamon supplements have shown inconsistent effects on fasting glucose levels (SOR: C, multiple systematic reviews and a single meta-analysis of disease-oriented outcomes). Supplements decreased fasting glucose levels in some studies, but the evidence isn't consistent and hasn't been correlated with clinically significant improvements in glycemic control.Beth Careyva, MD; Grant Greenberg, MD, MA, MHSA; Katarzyna Jabbour, PharmD, BCPS; Nicole Defenbaugh, PhD (Lehigh Valley Health Network, Allentown, PA); Joan Nashelsky, MLS (Family Practice Inquiries Network, Iowa City)Includes bibliographical reference
