Spice Up Your Eating: Cinnamon And PCOS

When you think of cinnamon, do foods like pumpkin bread, apple pie, spiced cider, oatmeal, and pumpkin spice lattes come to mind? Well, recent research provides some welcome news: Cinnamon may help women with PCOS better regulate their menstrual cycle, lower hormones, and even improve insulin and cholesterol levels.

Here’s what to know about this popular spice.

PCOS and Cinnamon

Despite the popularity of this popular spice, only three studies have examined the use of cinnamon in women with PCOS, all with favorable results. Here’s what the studies have found:

Lowers AMH Levels

In a double-blind, randomized, controlled trial, women with PCOS were randomly chosen to take 500 mg metformin divided into two doses or 100 mg of cinnamon for 6 months. Both groups saw significant reductions in anti-Mullerian hormone (AMH).

Improved Menstrual Regularity in PCOS

In a prospective, placebo controlled, double-blinded randomized trial, 45 women with PCOS were randomized to receive cinnamon supplements (1.5 g/d) or placebo for 6 months. Menstrual cycles were more frequent in patients taking cinnamon compared with patients taking placebo. Measures of insulin resistance or serum androgen levels did not change for either group.

Improved Insulin Resistance

In a small piolot study, 15 women with PCOS were randomized to cinnamon or placebo 8 weeks.The cinnamon group had significant reductions in insulin resistance.

Health Benefits of Cinnamon

Cinnamon use has also been shown to help those with type 2 diabetes.

In a double-blind study, 79 patients with type 2 treated with oral antidiabetics (such as metformin) or diet, were randomly assigned to take either a cinnamon extract or a placebo capsule three times a day for 4 months. The amount of cinnamon extract corresponded to 3 g (1 teaspoon) of cinnamon powder per day. The cinnamon group had a significantly better reduction of fasting glucose (10.3%) than in the placebo group (3.4%).

Based on these results, the researchers suggest that cinnamon extract seems to have a moderate effect in reducing fasting glucose levels in diabetic patients and possibly, women with PCOS. Reductions in glucose levels associated with cinnamon have also been found in individuals without diabetes.

Other research shows that cinnamon not only lowers fasting glucose levels but cholesterol levels too.

Sixty people with type 2 diabetes were divided randomly into six groups. The first 3 groups consumed 1, 3, or 6 g of cinnamon daily, while the remaining groups were given placebo capsules that corresponded to the number of capsules consumed for the three levels of cinnamon. After 40 days, all three levels of cinnamon reduced the mean fasting serum glucose (18-29%), triglyceride (23-30%), LDL cholesterol (7-27%), and total cholesterol (12-26%) levels.

How Cinnamon Works

Cinnamon seems to work by increasing the phosphorylation of insulin receptors which leads to improved insulin function and sensitivity. It may also reduce insulin levels by slowing the movement of food from the stomach into the small intestine (a part of digestion called “gastric emptying”) which also slows the breakdown of carbohydrates. Cinnamon has also been shown to affect adiponectin secretion from fat cells.

Side Effects of Cinnamon

Since it may lower glucose and insulin levels, you should discuss the use of cinnamon with your doctor. Careful monitoring of blood sugar levels is important to prevent hypoglycemia, which a lot of women with PCOS tend to experience as a result of elevated insulin levels. While side effects are very minimal, there is no need to exceed more than 2 teaspoons (6 grams) per day to get results.

Cinnamon can also be taken in a capsule form sold as cinnamon cassia extract to meet therapeutic dosages.

    I think most cooks associate cinnamon with sweet foods. Middle eastern cooking frequently uses cinnamon in savory dishes. So try cooking Moroccan it will be fun and you’ll get in more cinnamon. I find grating it from a stick has more flavor than buying it already ground.
