For most healthy adults, a common evidence‑based range for Ceylon cinnamon is about 0.5–3 grams (roughly ¼–1¼ teaspoons) of the powder per day, used for up to several months. Staying near 1 teaspoon (about 2–2.5 grams) daily in food is generally considered a cautious, practical upper limit for long‑term routine use.

Quick Scoop

  • Typical safe range:
    • 0.5–3 g per day of Ceylon cinnamon has been used safely for up to 6 months in adults.
* Many nutrition sources suggest ¼–1 teaspoon (≈0.5–2.6 g) per day as a reasonable everyday amount.
  • More conservative daily target:
    • Around ½–1 teaspoon per day (≈1–2.5 g) is a sensible goal for long‑term use in healthy adults, spread across meals.
  • Why Ceylon is “safer” than cassia:
    • Safety concerns with cinnamon mainly come from coumarin, which can stress the liver at high intakes.
* Ceylon cinnamon has far lower coumarin levels than common cassia cinnamon, so ordinary culinary amounts are well below the tolerable daily intake in most people.
  • When to be extra careful:
    • If you have liver disease, are pregnant, or take blood thinners or other chronic medications, discuss any regular supplement‑level cinnamon intake with your clinician, especially above about 1 g per day.
* High‑dose “therapeutic” regimens (for example 2–3 g or more as capsules, aimed at blood sugar control) should be supervised by a healthcare professional.
  • Supplements vs kitchen use:
    • Standard Ceylon cinnamon capsules around 500 mg once daily fall inside commonly used “possibly safe” ranges for adults.
* Using Ceylon cinnamon mainly as a spice in oats, smoothies, or coffee—up to about 1 teaspoon per day—is considered low‑risk for most healthy people.

Bottom line: For everyday cooking, aim for about ½–1 teaspoon of true Ceylon cinnamon per day, unless your healthcare provider gives different, personalized advice.
