For most adults, 1 teaspoon (about 2.6g) of common Cassia cinnamon daily is a safe upper limit due to its high coumarin content, which can harm the liver in large doses; Ceylon cinnamon is a safer daily choice because it has very low coumarin, allowing for 1-2 teaspoons (3-6g) or more. Clinical studies show benefits with 1-6g, but consistently exceeding 6g, especially Cassia, risks liver damage, so consult a doctor for therapeutic doses or if you have liver/bleeding issues.
Recommended cinnamon dosage
Some experts suggest 1/2 to 1 teaspoon (2-4 grams) of powder a day. Some studies have used about 1-6 grams of cinnamon. High doses might be toxic.
