How Much Cinnamon Tea per Day?

DetoxWater Editorial Team•Published November 5, 2026

There is no established daily amount of cinnamon tea; one small trial used 1–6 g of cinnamon per day in capsules, not tea. The amount appropriate for you depends on the cinnamon type, how strong the drink is, other cinnamon you consume, and your health and medications.

How much cinnamon tea can you drink per day?

There is no evidence-based number of cups that applies to everyone. A 1-cup (240 ml) serving is a standard measuring portion, not a recommended daily limit for cinnamon tea.

The small clinical trial mentioned above tested 1, 3 or 6 g of cinnamon daily in people with type 2 diabetes. Those amounts describe cinnamon in capsules, not the amount that transfers from a cinnamon stick or tea bag into water. They should not be treated as a tea recipe or a recommended daily dose.

If you enjoy cinnamon tea, treat it as a beverage rather than a supplement. Use a modest culinary amount, follow the product's preparation instructions, and don't assume that a stronger drink or more cups will provide greater benefits.

Why the cinnamon type matters

Cassia cinnamon generally contains more coumarin than Ceylon cinnamon. Coumarin is a naturally occurring substance that can affect the liver, particularly with substantial or prolonged exposure in susceptible people. Ceylon cinnamon generally contains less, but that does not establish an unlimited safe amount of its tea.

The amount of cinnamon and coumarin in a cup can vary with the product and preparation. A stick, a tea bag and ground cinnamon left in the drink are not interchangeable measures; check the label for the cinnamon type and consider cinnamon from foods and supplements as well.

Does the amount of cinnamon tea depend on your goal?

Hydration

Cinnamon tea can contribute fluid, but there is no established number of cups needed for hydration. Choose a strength you enjoy rather than trying to reach a cinnamon dose.

The liver and kidneys do most of the body's detoxification; cinnamon tea can support hydration, but it does not flush toxins from the body.

Blood sugar

There is no established cinnamon tea dose for managing blood sugar. A 2024 meta-analysis of 24 randomized trials found improvements in some blood sugar measures with cinnamon supplementation in people with type 2 diabetes, but it studied supplements, not cups of tea.

An earlier meta-analysis found no significant effect on HbA1c, a measure of longer-term blood sugar. These findings do not establish how much cinnamon tea to drink or make it a substitute for diabetes care.

Weight management

A 2020 meta-analysis of 12 trials found changes in some weight measures with cinnamon supplementation. That evidence does not establish an effective amount of cinnamon tea for weight loss. Drinking more cinnamon tea is not a proven way to lose weight.

What are the signs you're overdoing cinnamon tea?

Cinnamon can irritate the mouth or digestive tract in some people. If you develop mouth irritation, nausea or stomach discomfort after drinking cinnamon tea, stop drinking it and contact a healthcare professional if symptoms persist or are concerning. Get emergency help for signs of a severe allergic reaction, such as trouble breathing or swelling of the face or throat.

Liver problems may not cause early symptoms. Seek prompt medical advice if you notice yellowing of the skin or eyes, dark urine, or unexplained pain in the upper right abdomen, especially if you have been consuming substantial amounts of cinnamon.

Ask a healthcare professional before making strong cinnamon tea a daily habit if you have liver disease, have diabetes or take diabetes medication, or take medicines that can affect the liver. Do not change or stop prescribed medication because you drink cinnamon tea.

During pregnancy or breastfeeding, and for children, check with a healthcare professional before using cinnamon tea regularly or in concentrated amounts. Ordinary cinnamon in food and repeated use of a concentrated drink are different situations; a safe therapeutic tea dose has not been established.

Frequently asked questions

Does cinnamon tea contain caffeine?

Cinnamon itself is naturally caffeine-free. A packaged cinnamon tea can contain caffeine if it also includes tea leaves, so check the ingredients.

Can the color of cinnamon tea tell you its dose?

No. Color does not reliably show how much cinnamon or coumarin is in the drink, because products and preparation methods vary.

Does adding sugar change the amount of cinnamon in the tea?

Adding sugar does not remove cinnamon from the drink. It does add sugar, which is relevant if you are monitoring your blood sugar.
