What is the recommended dosage of cinnamon for managing blood sugar levels?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Cinnamon may help support healthy blood sugar levels, but there is no universally established recommended dose. Research suggests that 1 to 6 grams per day (roughly ½ to 2 teaspoons) may offer modest benefits, particularly for people with insulin resistance or type 2 diabetes. However, individual response varies, and cinnamon should not replace prescribed treatments.

Because blood sugar concerns can point to a range of underlying conditions—from prediabetes to hormonal imbalances—it's important to understand what's driving your symptoms before self-treating. Take a free, instant, online symptom check to get personalized insights and clear next steps.

Explanation

Cinnamon is a spice that some people use to help manage blood sugar levels. However, the exact amount that is best to take is not clearly known.

Reference 1 suggests that cinnamon may help lower blood sugar in people with type 2 diabetes, but the right dose is not clear. Some studies used doses between 1 and 6 grams per day.
Reference 2 points out that while some studies show cinnamon can help with blood sugar, more research is needed to know how much to take safely.
Reference 3 indicates that cinnamon might help improve blood sugar levels, but the results are mixed, and more studies are needed to find the best dose.

In summary, while cinnamon might help with blood sugar, there is no one-size-fits-all dose.
