How much cinnamon actually helps blood sugar?

Meta-analyses of randomised trials in type 2 diabetes typically pool doses of 1–6 g/day of powder or 500–1,000 mg/day of extract. Fasting glucose and HbA1c effects are real but modest — a helpful thread inside a broader diet, exercise, and medication plan.

Can I take cinnamon with my blood-sugar medication?

Small culinary amounts are fine. Standardised cinnamon extracts on top of insulin or a sulfonylurea (a common type of diabetes tablet) can add to their glucose-lowering effect. Talk with your clinician and watch for signs of hypoglycemia before adding a daily supplemental dose.

Cinnamon

The Essentials

Ceylon cinnamon is the safer bark for daily use. It holds far less of the hepatotoxic coumarin found in Cassia. Across pooled type 2 diabetes trials, the effects on fasting glucose, HbA1c and post-meal blood sugar are modest but real.

It is also one of the oldest Persian warming digestives. A stick simmered in tea after a heavy dinner does most of what tradition asked of it.

Culinary use of Ceylon is essentially unlimited. Supplemental doses need a floor, a ceiling and a look at the coumarin math.
