Chances are you have a bottle of cinnamon in your spice cupboard. And chances are you never thought of cinnamon as medicine.
However, cinnamon has been used medicinally since ancient times. This popular spice was used in ancient Egypt, China, and India for culinary and medicinal purposes, and its use has also been documented in the Bible.
There are two types of cinnamon: Ceylon and cassia, both derived from the bark of evergreen trees. Ceylon cinnamon is grown in South America, Southeast Asia, and the West Indies, while cassia cinnamon is grown in Central America, China, and Indonesia. Ceylon cinnamon bark looks like tightly rolled scrolls, while cassia cinnamon is more loosely rolled. Cassia is the variety most commonly sold in the United States.
Most people think of cinnamon as a flavoring for desserts or as a warm, robust scent for candles and potpourri. But this spice may do more than make your house smell good. Cinnamon has been shown to help lower blood glucose levels in people with Type 2 diabetes.
A study published in the journal Diabetes Care in 2003 looked at 60 men and women with Type 2 diabetes who were taking diabetes pills. The participants took either 1, 3, or 6 grams of cassia cinnamon or a placebo, in capsule form, for 40 days. After this time, blood glucose levels dropped between 18% and 29% in all three groups that received cinnamon. However, only the participants who had taken the smallest amount of cinnamon (1 gram) continued to have improved blood glucose levels 20 days after they stopped taking it, for reasons the researchers didn't quite understand.
In the study, cinnamon also helped lower triglycerides (a blood lipid) and LDL (or "bad") cholesterol levels. The benefits continued after 60 days, 20 days after participants had stopped taking cinnamon.
No significant changes in blood glucose or blood lipid levels occurred in the placebo group.
So, should you start shaking cinnamon on everything or start popping cinnamon capsules? First, keep in mind that this was a small study with only 60 subjects. Second, it was a short-term study, and the effects of taking cinnamon on a long-term basis aren't known. Third, there's no evidence that cinnamon helps people with Type 1 diabetes.
On the other hand, cinnamon is relatively safe. Keep in mind, though, that, some people may be allergic to cinnamon, and that cinnamon in large amounts may cause mouth sores or burn the skin. Also, as with any kind of supplement, it's important to discuss its use with your health-care provider.
One gram of cinnamon, the lowest (and most effective) amount used in the study, is about ⅕ teaspoon. Three grams is about ½ teaspoon, and 6 grams is a little more than a teaspoon. If, after checking with your health-care provider, you want to see for yourself if cinnamon might help improve your blood glucose levels, start with the smallest dose (1 gram). Be sure to check your blood glucose levels often and keep good food and blood glucose records. Then, try sprinkling cinnamon on cereal and toast, or in your coffee, tea, or cocoa, spread out over the day. Another option is to take cassia cinnamon in capsule form, taking 500 milligrams twice daily. Just remember that cinnamon supplements, like all supplements, are not regulated by the U.S. Food and Drug Administration (FDA) in terms of quality and effectiveness.
Stop using cinnamon immediately and call your health-care provider if you notice any side effects. If you don't notice any improvement in your diabetes control after several weeks, don't despair. You can still enjoy the rich, warm flavor of this ancient spice.

I started use cinnamon on oatmeal every morning, for over a year now. It works within a month I noticed my sugar tested lower. I told my Doctor and he was very surprised. My next appointment, which was 6 months after starting the cinnamon, my Dr. had to lower my Glyburide from 2 pills a day to 1/2 a pill twice a day, then to 1/2 a pill once a day with dinner. My cholesterol levels are better also. I just bought some cinnamon capsules, so I have them if I need them, maybe when traveling. I missed one day in over a year. I am very Pleased! It works! Granny

Hi Granny and gvra28
Granny, I'm glad to hear that cinnamon is working for you! And gvra28, I hope it works as well for you as it has for Granny. Don't forget to let your doctor know that you're taking it.

Amy, I'm confused. I've read several articles about this same study regarding cinnamon, and I want to be sure I get it straight as to the dose I should try. You suggested trying 500 mg of cinnamon twice a day, but other articles I've read claim that people using 6 grams a day lowered their blood sugar substantially in as little as 20 days. Do you know anything about the 6 grams per day giving the fastest (if not the longest lasting) benefit? Thanks in advance for any light you can shed on this.
Posted by: Pootsie | Jan 11, 2007 12:35 PM
Hi Pootsie,
You raise a good question, and it's understandable why you're confused. The information you're referencing is partly related to one study in particular that used various levels of cinnamon. The researchers found that the 6-gram dose of cinnamon lowered glucose levels more than the other doses did, and in a shorter amount of time. The issue, though, is that no one is really sure what the lowest, most effective dose of cinnamon is. And when it comes to medications and supplements, you always want to take the lowest dose possible that will still yield beneficial results. While cinnamon is relatively safe, some people may be allergic. If you're planning on trying cinnamon, first let your physician know. The key is to start with a low dose, and increase gradually, if you need to. As the saying goes, "Start low, go slow".

I started taking Cinnamon capsules about 4 months ago because of my high cholesterol. The doctor wanted to put me on some type of medecine and im the type of person that would rather treat something with a natural remedy rather than take a perscreption drug. Before I started taking Cinnamon my Cholesterol level was 245 and now it is at a borderline level of 230. The longer I take the cinnamon the better my cholesterol gets. You can find cinnamon almost everywhere but I order mine through a company called Health Quest Technologies. They put me on a program where I get my cinnamon automatically charged to my credit card every two months and they send me out one bottle which last me two months!

I just started taking Cinnamon capsules about a week ago and have noticed that I am having mild hot flashes all during the day and night. Has anyone else experienced a problem like this.
Posted by: sandyh | Nov 27, 2007 07:44 PM
Hi Sandy,
While cinnamon is a relatively safe herb, there are some reported side effects, including contact dermatitis, mouth lesions, skin rash, and facial flushing. It's therefore quite possible that you're experiencing a reaction to the cinnamon. I'd suggest you stop taking them for a few days and see if your hot flashes disappear. If it looks like they're linked, you might either need to stop the cinnamon altogether or decrease your dose. You can also put up with the hot flashes unless they're particularly bothersome. Also, if the cinnamon doesn't appear to be helping your blood glucose control, there may be no benefit in continuing to take it.

Why cinnamon works on my husband aand not on my diabetes type 2. Is it because he takes medication and I don,t yet.
Gladys Sharat
Posted by: GSharat @aol.com | Dec 10, 2007 08:30 AM
Hi Gladys,
Your situation illustrates a very important point about supplements - they may work for some and not for others. There are probably several reasons why cinnamon may not be working as well for you as it does for your husband, including your average blood glucose levels, how long you've been taking cinnamon and how much you've been taking, and the fact that he takes medicine for his diabetes, while you don't. How have your blood glucose levels been running? If they're running too high, cinnamon may not do much to lower them. Also, one study has concluded that cinnamon isn't effective for reducing insulin resistance and blood glucose levels in postmenopausal women. So, as the saying goes, "more research is needed". Talk with your doctor about whether you should continue taking cinnamon or not.

Hi! I found out I am a borderline type 2 diabetic a few months ago. So I am still experimenting with what foods spike my glucose levels. When I eat something that makes my sugar go way up...I mix about 3/4 of a teaspoon of cinnamon with just a sprinkle of Splenda and a tiny dab of margarine (it makes it go down way easier). Follow it with a glass of water. Within 15 minutes to a half an hour...my glucose level drops way down. Bought the pills today and am going to give them a try. Thank you for the posts...I was a little leary of taking the pills.
Posted by: breezinthru52 | Dec 24, 2007 10:53 PM
Hi Diane,
No, it's not recommended that pregnant women take cinnamon as a supplement. Also, if you take any other dietary or herbal supplements, be sure to let your provider know.
Posted by: acampbell | Feb 05, 2008 01:30 PM
I have used this supplement and my glucose level drop over 20 points. So, it you are concerned about your sugar levels then please go for the cinnamon pills! They are fantastic!

I have been reading that some cinnamon could contain "coumarin" and that it could be toxic to the liver. Would it be found in cinnamon pills? Which types of cinnamon would it be found in>
Posted by: linda | Mar 22, 2008 05:45 PM
Hi linda,
A type of cinnamon, called cassia cinnamon, may contain varying amounts of coumarin, a compound that may cause liver damage in high doses, at least according to animal studies. If you take a supplement, try to find one that lists "water soluble" cinnamon on the label. And don't take very large doses for an extended period of time. Also, this is a good example of why you should always discuss the use of any supplement with your provider.

Hi,
I have benn drinking this cinnamon honey tea for past two days(one time). i feel very tired after drinking this tea and also sweating.

I haven't check my sugsr lavel recently. my question is is it ok to drink the tea, bcz i really need to lose some weight. i would really appreciate if someone reply me back. thanks in advance.
Posted by: abi | Apr 30, 2008 06:22 PM
Hi abi,
What are the ingredients in your tea besides cinnamon and honey? Is this sold as a "weight loss" tea? Some weight loss teas have herbs or other ingredients that can cause side effects. I'd suggest stopping the tea for a while and see if you feel better. Also, you might start checking your blood glucose levels again. And if you continue to have symptoms, it's a good idea to speak to your provider.
Posted by: acampbell | May 01, 2008 02:40 PM
Thanks for your reply acambell. I am taking cinnamon pills now. I take one in the morning and 1 at night, is it ok take it bcz i read your post about the coumarin and i am confused. I would really appreciate if you reply me back. thankyou.
Posted by: abi | May 13, 2008 01:48 PM
Hi abi,
It's hard to say without knowing what type and what amount of cinnamon you're taking. Make sure you've purchased your supplement from a reputable source. And be sure to follow the dosing instructions on the bottle. If you're still unsure, ask your physician, pharmacist or dietitian.
Posted by: acampbell | May 13, 2008 03:13 PM
Thanks again Acambell, i am taking 500mg twice a day and it is a spring valley cinnamon capsules. Could you pls tell me how could i find if this capsules contains coumarin or not. The instructions says 2 a day. I bought it from walmart. I want to know if i can take (cinnamon+ honey +hotwater )tea with food, bcz i can't take this tea first think in the morning it makes me sick. I really want to take this tea for weight loss.thanks
Posted by: abi | May 15, 2008 09:48 AM
Hi abi,
I suggest you contact the company that manufactures the supplement, Spring Hill. You can ask them if the cinnamon they use is water soluble. Chances are that the dose you're taking is pretty safe; just don't take more than what is recommended.
Posted by: acampbell | May 18, 2008 04:44 PM
Five members of our diabetes support group have used cinnamon capsules for the past 6 month...with NO positive results. Recent studies have generally shown it does not work. However, today my wife's cardiologist said it DOES work (as shown in yet another study) but you must use Ceylon Cinnamon, not the cheaper cinnamon in most supplements.
I might try this for six months. The cardiologist said the dose should be one teaspoon after lunch and the same amount after dinner. Good luck.

So I'd like to know what to do.
My Doctor is not really knowledgeble about this matter.
Please help!

Hi pcammar50,
I can't really give you advice on which supplements to take or not to take. However, as far as garlic goes, this supplement is relatively safe, although it shouldn't be taken if you take any blood thinning medicines. Garlic may not lower your LDL cholesterol all that much, according to recent research. Cinnamon is also fairly safe to take, but there's no conclusive evidence that it helps to lower cholesterol. I'd suggest you meet with a dietitian to discuss lifestyle changes that you can make. Ask a dietitian and your doctor about possibly using a plant stanol supplement. If your LDL is as high as you indicate, though, you may need to take medicine. And always remember to tell your doctor about any supplements that you take.

Please advise for gestation diabetics is it safe to use Cinnamon on a daily basis.

Hi KJ,
See my comment from Feb. 5, above. Cinnamon isn't recommended for use during pregnancy.

I can not get my sugar reading down below 242. I take 2 metformin a day. Can I take 3 a day? I need help quickly. I am seeing a Dr. every 3 months. But he's really no help.
Posted by: linda c | Jul 20, 2008 11:34 AM
Hi Linda,
Are you following a meal plan and getting physical activity? I wouldn't recommend increasing your metformin dose without talking with your doctor. My advice is to start checking your blood glucose levels several times a day and recording your results in a log book. At your next appointment with your doctor, show him the results. Ask him what your A1C is (goal is less than 7), too. Be firm and let him know that you're not happy with your numbers, as they are out of target range. Ask him what your options are, in terms of medication, whether it's increasing your metformin or adding another medication. If he won't help you, consider switching providers, if you need to. This is your diabetes and your health, so you need to be your own advocate. Good luck!

HI: im shahana,I like to ask how you make your cinamon ,hony tea
Posted by: shahana | Jul 29, 2008 12:59 PM
In reading the above, I see that in some cases cinnamon helps type 2 and pre-diabetics with their blood glucose. I am working on not becoming pre-diabetic.
Question 1: I take 1000 mg (2 capsules total) each morning. Is it better to take one in the AM and the second one in the PM?
Question 2: I also read that people experience "hot flashes". I've been taking the cinnamon pills for about 3 months, and just recently noticed feeling extra warm and sweaty during the day, and wonder if splitting the two pills into AM and PM doses would help offset this hot feeling but keep with helping the blood glucose?
Question 3: Is there anything connecting cinnamon with the increasing or decreasing high blood pressure.
Question 4: Is there anything connecting cinnamon with the increasing or decreasing heart rate or heart beats?
Thank you!
Posted by: fredsmom | Aug 21, 2008 10:42 PM
Hi fredsmom,
There isn't a lot of information available as to the best dose of cinnamon to take, and studies that have been done with cinnamon have been inconsistent. However, cinnamon is a fairly safe supplement, unless you happen to be allergic. To answer your questions, I'm not sure if it matters that you split the dose; but, if you do experience flushing, you might try taking one capsule in the am and one in the pm. Cinnamon may lower blood pressure levels, although I've read that it may increase heart rate. If you do experience increased heart rate and flushing, you might try decreasing your dose. Make sure you let your provider know that you're taking cinnamon, as well.

Why isn't Cinnamon good for Pregnancy. Untold by doctors I was borderline diabetic - insulin resistant in Nov 07. I am now 3mo pregnant and of course have gestational diabetes. In addition my blood pressure has been running 140/100.
I would like to take some type of supplement and cinnamon was recommended by a friend.
If the only reason not to take it is that it might decrease my sugars too much, then wouldn't I be able to monitor that with my meter - which I have to use at least 7x/day anyway.
As for it possibly increasing the heart rate - is that in any way related to my blood pressure being so high?
Cinnamon itself wouldn't cause any harm to the fetus would it?
Yes, I know not much info is know, but I can tell you the docs in MO are not into herbal remedies, they are all AMA well trained :-)
Thanks
Posted by: aziemer | Aug 25, 2008 09:03 PM
Hi aziemer,
The issue with cinnamon use during pregnancy has to do with lack of sufficient data to prove that it's safe, and not due to its potential glucose-lowering effects. The Natural Medicines Comprehensive Database, which is a professional database of supplements, as well as the PDR for Herbal Medicine advise against using cinnamon during pregnancy and breastfeeding. In fact, the PDR for Herbal Medicines states that cinnamon is used in Chinese medicine to treat amenorrhea (lack of menstruation). It's unfortunate that we don't know enough about cinnamon, but as the saying goes, it's better to be safe than sorry. It's fine to use cinnamon as a flavoring in foods, but most medical practitioners would advise against taking it as a supplement during pregnancy.

I used cinnamon sticks when I was quitting smoking. I used them to replace thehabit of holding something. In time I notice I was having low blood sugar attacks. I didn't even know that cinnamon could lower your blood sugar until I googled it. So there is something to it. Karen

You should never take large doses of what is called "cinnamon" or "saigon cinnamon" in this country, as these are really "cassia" (a cousin of "real cinnamon"), which is toxic in large doses. The only 2 ways to avoid this: (i) Purchase
"real cinnamon" or "Ceylon cinnamon", directly from Sri Lanka (from companies such as Dru Era), or (ii) purchase water soluble cinnamon pills (the toxic part of cinnamon is not water soluble) under the generic name of Cinnulin PF (various manufacturers).
Posted by: d.wayne | Oct 05, 2008 02:27 PM
Actually, the key studies involving the use of cinnamon on blood glucose and blood lipid levels have used cassia cinnamon, and not Ceylon cinnamon (although Ceylon cinnamon is more commonly used in the U.S.). However, Ceylon cinnamon does contain an ingredient also thought to lower glucose levels; it just hasn't been as widely studied. I agree that it's best to purchase water soluble or water extracted forms of cinnamon to limit exposure to any toxins.
