Well, Dr. B does not recommend Cinnamon. The research on Cinnamon is inconclusive. I never found it affected my blood sugar one way or the other, even taking capsules of the stuff. I would also note that Ms. Wexler has a book on the topic: Cinnamon. It is probably prudent to consider whether the article may be part of her marketting outreach for her book.
Here is what I know about Cinnamon (1)
Cinnamon made the news in 2003 with the publication of a study in the journal Diabetes Care (2). The study reported that cinnamon supplementation (1, 3, or 6 gms per day) was associated with a reduction in fasting glucose (18-29%), triglycerides (23-30%), and LDL cholesterol (7-27%) in patients with type 2 diabetes. Since then, two other studies have been published which reported no significant changes in fasting plasma glucose or A1c’s (glycosylated hemoglobin) with cinnamon administration. (2)
Fewer than one hundred patients received cinnamon in all three studies combined, the studies were relatively short, and it is difficult to standardize cinnamon, all of which make it difficult to draw conclusions. If you do decide to try cinnamon, you certainly need to discuss it with your provider because if cinnamon does reduce blood sugar, you might have hypoglycemic episodes. A reasonable dose would probably be 1.5 to 2 grams per day; however, I would suggest not taking this until more is known about it.
In a recent three-month study, 43 non-insulin-dependent people with type 2 diabetes were given either a daily dose of 1000 milligrams of cinnamon or a placebo.
In contrast, a previous study found that a daily cinnamon hit caused a dip in blood sugar and cholesterol in people with type 2. None of that first group was taking diabetes medicines, however, unlike the current group, most of whom were on diabetes medications.
- Two types of Cinnamon – Cassia and Ceylon
- Cassia has more coumarin than Ceylonese
- Almost all Cinnamon in the US is Cassia, Ceyonese is rare and expensive
- Coumarin, similar to warfarin is toxic in large quantities
