Because cinnamon and cinnamon extracts have demonstrated benefits in people with insulin resistance and type 2 diabetes, it has potential benefits in people with metabolic syndrome.^7,8 A placebo-controlled trial that included 116 participants with metabolic syndrome found 3 grams of cinnamon per day for 16 weeks improved blood glucose, triglyceride, and cholesterol levels, as well as waist circumference, blood pressure, and blood glucose control.⁹ In a randomized controlled trial, cinnamon reduced signs of metabolic disease in people with type 2 diabetes: after eight weeks, study participants receiving 3 grams of cinnamon per day had lower blood glucose levels, triglyceride levels, body weight, and body fat, and improved blood glucose control.¹⁰ Similarly, in a placebo-controlled trial with 140 participants with diabetes, taking 1 gram of cinnamon daily for three months improved glucose and lipid metabolism and was associated with body fat and weight loss, with stronger effects in those with more severe obesity.¹¹ Placebo-controlled trials in people with type 2 diabetes show cinnamon can reduce high blood pressure in people with metabolic disease.^12,13 Furthermore, a meta-analysis of controlled trials showed cinnamon can also reduce high blood pressure, with greatest efficacy when used at a dose of 2 grams per day or less for at least 12 weeks.¹⁴
