Throughout history, cinnamon has been used for medicinal purposes, with ancient Chinese and Ayurvedic medicine practitioners utilizing it to treat various ailments and afflictions. 

Today, cinnamon remains a staple in many cuisines worldwide, prized for its warm, sweet, and aromatic flavor. Its potential health benefits continue to be explored and expounded upon through modern scientific research, being highly touted as a natural and alternative remedy.

Types of Cinnamon

While many people may be familiar with the general taste and aroma of cinnamon, not everyone is aware that there are distinct varieties available in the market. It is essential to understand that regardless of this fact, no type of cinnamon is considered "fake," as they all come from the bark of various species of the Cinnamomum tree. There are two main varieties/ types that you can purchase, namely:

types of cinnamon

Ceylon Cinnamon

Ceylon cinnamon, scientifically known as Cinnamomum verum, is native to Sri Lanka and is often referred to as "true" cinnamon. This variety is characterized by its light brown color, thin and delicate bark, and a more refined, complex flavor profile compared to other types. 

Ceylon cinnamon has a subtle sweetness, accompanied by a hint of citrus and a mild, warming spiciness. Due to its delicate nature and labor-intensive harvesting process, Ceylon cinnamon is generally more expensive than other varieties. It is highly prized in gourmet cooking and is often used in desserts, pastries, and beverages where its nuanced flavor can shine through.

Cassia Cinnamon

On the other hand, Cassia cinnamon, derived from the Cinnamomum cassia tree, is more widely available and commonly used in many parts of the world (especially low-income countries). 

Cassia cinnamon is native to China and is also cultivated in other regions of Southeast Asia. It has a thicker, darker bark compared to Ceylon cinnamon and tends to have a more intense, spicy flavor with a slightly bittersweet note. Cassia cinnamon contains higher levels of cinnamaldehyde, the compound responsible for its strong, pungent aroma and flavor. This variety is often preferred in baking and savory dishes, as its bold taste can stand up to other ingredients. Cassia cinnamon is also more affordable than Ceylon cinnamon, making it a popular choice for everyday use.

Other Types

Apart from Ceylon and Cassia, there are other types of cinnamon that are worth mentioning. Saigon cinnamon, also known as Vietnamese cinnamon, is a variety of Cassia cinnamon grown in Vietnam. 

It has a higher cinnamaldehyde content than regular Cassia, resulting in a more robust, spicy flavor. Saigon cinnamon is often used in traditional Vietnamese cuisine but is gaining popularity among bakers and culinary enthusiasts worldwide.

Korintje cinnamon (Cinnamomum burmannii), another variety of Cassia cinnamon, is primarily cultivated in Indonesia. It has a smooth, warm flavor with a slight sweetness, making it a versatile choice for various applications. Korintje cinnamon is commonly used in commercial food production and is often the type found in ground cinnamon sold in supermarkets.

Benefits Of Cinnamon Consumption

Blood Sugar Regulation

Cinnamon derived from various species of the Cinnamomum family has been shown to possess significant blood sugar-lowering properties. The active compounds responsible for this effect are believed to be polyphenols, particularly cinnamaldehyde and proanthocyanidins. These compounds work through several mechanisms to regulate glucose metabolism and improve insulin sensitivity.

blood sugar regulation

One of the primary ways it lowers blood sugar is by enhancing insulin signaling and glucose uptake in cells. Cinnamaldehyde has been found to activate the insulin receptor and downstream signaling pathways, leading to increased translocation of glucose transporter 4 (GLUT4) to the cell membrane. 

This process facilitates the uptake of glucose from the bloodstream into cells, thereby reducing blood sugar levels. Additionally, cinnamon has been shown to inhibit the activity of several enzymes involved in carbohydrate digestion, such as alpha-glucosidase and alpha-amylase, slowing down the absorption of glucose in the small intestine and preventing postprandial spikes in blood sugar.

Cinnamon has been demonstrated to improve insulin sensitivity by reducing insulin resistance. Insulin resistance occurs when cells become less responsive to insulin, leading to elevated blood sugar levels. 

The polyphenols in cinnamon have been found to enhance the expression of peroxisome proliferator-activated receptor gamma (PPAR-γ), a transcription factor that plays an important role in regulating insulin sensitivity. By activating PPAR-γ, cinnamon improves the body's ability to respond to insulin and efficiently utilize glucose.

Another mechanism through which cinnamon exerts its blood sugar-lowering effect is by modulating the expression of genes involved in glucose and lipid metabolism. 

Cinnamon can upregulate the expression of glucose transporter genes, such as GLUT1 and GLUT4, while downregulating the expression of genes involved in gluconeogenesis, the process by which the liver produces glucose. 

This dual action of increasing glucose uptake and reducing glucose production contributes to the overall reduction in blood sugar levels.

The anti-inflammatory and antioxidant properties may indirectly contribute to its blood sugar-lowering effects as well. Chronic inflammation and oxidative stress have been linked to the development of insulin resistance and type 2 diabetes. 

The polyphenols in cinnamon have been shown to inhibit the production of pro-inflammatory cytokines and reduce oxidative stress markers, potentially mitigating the negative impact of these factors on glucose metabolism.

It is important to note that while the blood sugar-lowering effects of cinnamon have been demonstrated in numerous studies, the magnitude of the effect may vary depending on the individual, the form of cinnamon consumed, and the dosage. 

Nevertheless, the available evidence suggests that incorporating any sort of cinnamon into a balanced diet (at a reasonable dose) may provide beneficial effects on blood sugar regulation, particularly for individuals with prediabetes or type 2 diabetes.

Cardiovascular Health

One of the primary mechanisms through which cinnamon supports cardiovascular health is by improving endothelial function. The endothelium, which is the inner lining of blood vessels, is a necessary regulator of vascular tone and maintaining healthy blood flow. 

Cinnamaldehyde and cinnamic acid have been found to stimulate the production of nitric oxide, a potent vasodilator, in the endothelium. 

Nitric oxide relaxes smooth muscle cells in the blood vessels, leading to vasodilation and improved blood flow. This action helps to maintain healthy blood pressure levels and reduces the workload on the heart.

The antioxidant actions of cinnamon also protect the cardiovascular system from excess oxidative stress. Oxidative stress, caused by an imbalance between the production of reactive oxygen species and the body's ability to neutralize them, can lead to endothelial dysfunction and promote the development of atherosclerosis. 

The compounds in cinnamon, particularly cinnamaldehyde and eugenol, scavenge free radicals and inhibit lipid peroxidation, thereby reducing oxidative stress and preventing damage to the blood vessels.

Inflammation plays a significant role in the development and progression of cardiovascular diseases and cannot be underestimated. Cinnamon demonstrates anti-inflammatory properties, which can help mitigate chronic low-grade inflammation associated with cardiovascular disorders. 

The cinnamic acid and eugenol found in cinnamon inhibit the production of pro-inflammatory cytokines and downregulate the expression of inflammatory mediators. By reducing inflammation, cinnamon helps to maintain the integrity of the blood vessels and prevents the formation of atherosclerotic plaques.

But wait, there’s more. Cinnamon has been found to have beneficial effects on blood lipid profiles, too. The regular consumption of cinnamon can help lower total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride levels while increasing high-density lipoprotein (HDL) cholesterol levels. 

These improvements in lipid profiles are attributed to the ability of cinnamon to inhibit cholesterol synthesis and enhance the expression of LDL receptors, leading to increased LDL uptake and clearance from the bloodstream. By maintaining healthy blood lipid levels, cinnamon reduces the risk of all-cause cardiovascular episodes.

Digestion and Gut Health

Do you have memories of your grandma using cinnamon-based remedies to treat your upset tummy? Turns out she was on to something.

One of the primary ways cinnamon supports digestion is through its carminative effects, which means it helps to prevent or alleviate gas and bloating in the digestive tract. 

Cinnamon contains several essential oils, which may help to relax the smooth muscles of the intestines, facilitating the passage of gas and reducing discomfort. These compounds also exhibit antispasmodic properties, helping to ease stomach cramps and abdominal pain associated with indigestion or irritable bowel syndrome (IBS).

Cinnamon can also help to stimulate specific fat digestive enzymes, which are crucial for breaking down lipids and enabling proper nutrient absorption. By increasing the activity of enzymes like lipase, and pepsin, cinnamon can optimize the digestion of fats, and proteins, respectively. 

This enhanced enzymatic activity not only improves overall digestive efficiency but also helps to prevent undigested food particles from lingering in the gut, which can lead to fermentation, gas production, and gastrointestinal discomfort.

In addition to its digestive-supportive properties, cinnamon has been shown to promote gut health by modulating the gut microbiome. The gut microbiome refers to the vast community of microorganisms residing in the digestive tract, which play a vital role in maintaining overall health and well-being. 

Cinnamon possesses prebiotic properties, meaning it can selectively help to act as nourishment to stimulate the growth and activity of beneficial gut bacteria, such as Bifidobacteria and Lactobacilli. 

These friendly bacteria help to maintain a healthy balance within the gut microbiome, preventing the overgrowth of harmful bacteria that can lead to digestive issues and compromised immune function.

Cinnamaldehyde, one of the primary active compounds in cinnamon, has been shown to inhibit the growth of various pathogenic bacteria, including Escherichia coli, Salmonella, and Helicobacter pylori, which are known to cause gastrointestinal infections and ulcers. 

By keeping these harmful microbes in check, cinnamon can help to maintain a healthy gut environment and reduce the risk of developing digestive disorders.

The anti-inflammatory effects of cinnamon can also be beneficial for individuals with inflammatory bowel diseases (IBDs), such as Crohn's disease and ulcerative colitis. These conditions are characterized by chronic inflammation in the digestive tract, leading to symptoms like abdominal pain, diarrhea, and leaky gut syndrome.

While these effects are promising, do not attempt to use cinnamon solely as a means of managing illness. Always consult with a qualified medical professional.

Potential Cognitive and Neurological Benefits

Did you know that cinnamon has demonstrated numerous beneficial effects on brain function and neurological health? Yes, there is much to discuss here.

One of the most notable cognitive support actions of cinnamon is its ability to enhance memory and learning. Cinnamon extract can improve spatial memory, recognition memory, and overall cognitive performance. 

These effects are attributed to cinnamon's ability to modulate neurotransmitter levels, particularly acetylcholine, which plays a crucial role in memory formation and retrieval. Additionally, cinnamon has been found to promote the growth and differentiation of neurons in the hippocampus, a region of the brain that is largely involved in learning and memory.

The antioxidant and anti-inflammatory properties also contribute to its neuroprotective effects. The brain is particularly vulnerable to oxidative stress and inflammation, which can lead to neuronal damage and cognitive decline. 

Cinnamaldehyde and proanthocyanidins in cinnamon help scavenge free radicals, reduce lipid peroxidation, and inhibit the production of pro-inflammatory cytokines in the brain. By mitigating oxidative stress and inflammation, cinnamon may help preserve neuronal integrity and maintain optimal brain function.

Cinnamon has even been implicated in the regulation of glucose metabolism in the brain. The brain relies heavily on glucose as its primary energy source, and impaired glucose metabolism has been linked to cognitive impairment and neurodegenerative disorders. 

Cinnamon can enhance insulin sensitivity, improve glucose uptake, and stabilize blood sugar levels, thereby ensuring a steady supply of energy to the brain. This action may be particularly beneficial for people with diabetes or those at risk of developing neurodegenerative conditions associated with impaired glucose metabolism, such as Alzheimer's disease.

Another potential cognitive benefit of cinnamon is its ability to inhibit the formation and aggregation of beta-amyloid plaques, which are a hallmark of Alzheimer's disease. Beta-amyloid plaques are toxic protein aggregates that accumulate in the brain, leading to neuronal dysfunction and cell death. 

Studies have shown that cinnamon extract can reduce beta-amyloid levels, prevent their aggregation, and protect neurons from beta-amyloid-induced toxicity. These findings suggest that cinnamon may have potential therapeutic applications in the prevention and management of Alzheimer's disease.

Lastly, cinnamon has been reported to have mood-enhancing and stress-reducing properties, which can indirectly support cognitive function. Chronic stress and mood disorders are known to have detrimental effects on cognitive performance, including impaired attention, memory, and decision-making. 

Cinnamon helps modulate the levels of neurotransmitters involved in mood regulation, such as serotonin and dopamine, and to reduce cortisol levels, a hormone associated with high-stress states. By promoting emotional well-being and reducing stress, cinnamon may contribute to improved cognitive function.

May Support Weight Loss

Is this your twenty-fifth attempt at losing weight? Many of us have been there. The important thing, however, is to eliminate what doesn’t work and to try new things. Have you tried cinnamon yet?

Cinnamon has the potential to support weight loss through several mechanisms. One of the primary ways cinnamon aids in weight management is by regulating blood sugar levels. 

By enhancing the body's ability to respond to insulin effectively, cinnamon helps prevent blood sugar spikes and crashes, which tend to coincide with increased hunger and cravings for sugary or high-carbohydrate foods. 

Stable blood sugar levels promote feelings of satiety and reduce the likelihood of overeating, thereby supporting weight loss efforts.

Cinnamon also influences the metabolism of glucose and lipids. Consuming cinnamon can help slow down the rate at which glucose is absorbed into the bloodstream after a meal. This delayed absorption not only helps maintain stable blood sugar levels but also prolongs the feeling of fullness, reducing the desire to consume more calories. 

Additionally, cinnamon has been shown to inhibit the activity of certain digestive enzymes, such as alpha-glucosidase and pancreatic amylase, which are responsible for breaking down carbohydrates. By slowing down the digestion of carbohydrates, cinnamon can further contribute to a more gradual release of glucose into the bloodstream, preventing sudden spikes in blood sugar levels and promoting a sense of satiety.

Another mechanism through which cinnamon may support weight loss is by boosting metabolism and increasing thermogenesis. Thermogenesis is the process by which the body generates heat, and it plays a role in energy expenditure. 

Some of the compounds found in cinnamon, particularly cinnamaldehyde, can stimulate thermogenesis and enhance metabolic activity. By increasing the body's metabolic rate, cinnamon may help burn more calories and fat, leading to weight loss over time. 

Cinnamon may even help to activate certain proteins involved in lipid metabolism, such as peroxisome proliferator-activated receptor gamma (PPAR-γ) and fatty acid synthase (FAS). These proteins can regulate the storage and breakdown of fats in the body. By modulating their activity, cinnamon may help reduce fat accumulation and promote the utilization of stored fat for energy.

It is important to note that while cinnamon has shown promise in supporting weight loss, it should not be relied upon as a sole solution. Incorporating cinnamon into a balanced diet and regular exercise routine can provide additional benefits and enhance overall weight management efforts. 

This is why Lean was formulated. By utilizing a synergistic blend of pro-metabolic and support agents, you can achieve safe and sustainable weight loss.

Possible Reduction In Cancer Risk

Cinnamon has been the subject of numerous studies investigating its potential to reduce cancer risk. The primary active compounds in cinnamon, cinnamaldehyde, and procyanidins, have demonstrated promising anti-cancer properties through various mechanisms of action.

One of the main ways it demonstrates potential is via its potent antioxidant activity. Cinnamaldehyde and procyanidins have been shown to scavenge free radicals and reactive oxygen species (ROS), which can cause oxidative stress and damage to cellular components, including DNA. 

By neutralizing these harmful molecules, cinnamon may help prevent the initiation and progression of cancer. Additionally, cinnamon has been found to increase the activity of endogenous antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase, further enhancing the body's defense against oxidative stress.

Chronic inflammation has been linked to the development and progression of various types of cancer as well. Some of the compounds in cinnamon may help to modulate the production of pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), and inhibit the activity of inflammation-promoting enzymes like cyclooxygenase-2 (COX-2) and lipoxygenase (LOX).

Cinnamon also demonstrates anti-proliferative and apoptotic effects on various cancer cell lines. Cinnamaldehyde and procyanidins can inhibit the growth and survival of cancer cells by inducing cell cycle arrest and promoting programmed cell death (apoptosis). 

These compounds have demonstrated efficacy against a range of cancer types, including breast, colon, prostate, lung, and liver cancer. 

By selectively targeting cancer cells while leaving healthy cells unharmed, cinnamon may help reduce the risk of cancer development and progression.

Some findings also show cinnamon's potential to modulate signaling pathways involved in cancer. For example, cinnamaldehyde inhibits the activation of nuclear factor-kappa B (NF-κB), a transcription factor that regulates the expression of genes involved in inflammation, cell proliferation, and survival. By suppressing NF-κB signaling, cinnamon may help prevent the activation of cancer-promoting genes and reduce the risk of malignant transformation.

Additionally, cinnamon may enhance the efficacy of conventional cancer therapies, such as chemotherapy and radiation. It may sensitize cancer cells to these treatments, potentially allowing for lower doses and reduced side effects. This synergistic effect may improve treatment outcomes and quality of life for cancer patients.

Potential Risks and Side Effects

Blood Thinning Effect

Cinnamon contains a naturally occurring compound called coumarin. While coumarin is present in many plants and essential oils, it has been the subject of concern due to its potential health risks when consumed in high amounts. 

coumarin molecule

See, coumarin is known to have anticoagulant properties, meaning it can interfere with the body's natural blood clotting processes. Warfarin, one of the most popular blood thinners in the world, is derived from this compound.

In individuals with pre-existing blood clotting disorders or those taking other blood-thinning medications, excessive consumption of coumarin could lead to an increased risk of bleeding and related but severe complications.

Liver Damage

Some studies have suggested that long-term exposure to high levels of coumarin may have hepatotoxic effects, potentially causing damage to the liver. Animal studies have shown that coumarin can lead to liver enlargement and even liver failure in extreme cases. 

However, it is important to note that the coumarin content varies significantly between different types of cinnamon. Ceylon cinnamon, also known as "true cinnamon," contains relatively low levels of coumarin compared to Cassia cinnamon, which is more commonly found in grocery stores. 

Cassia cinnamon has been found to contain substantially higher amounts of coumarin, leading to concerns about its regular consumption.

Allergic Reactions

Cinnamon can cause allergic reactions in some individuals. The severity of these reactions can range from mild to severe, depending on the person's sensitivity. Most of this risk is attributed to cinnamaldehyde. 

Symptoms of a cinnamon allergy may include itching, hives, swelling of the lips, tongue, or throat, difficulty breathing, and in rare cases, anaphylaxis, a life-threatening reaction. People with a history of food allergies or allergic reactions to other spices may be at a higher risk of developing a cinnamon allergy. 

Additionally, those with a sensitivity to balsam of Peru, a fragrance ingredient, may also react to cinnamon due to cross-reactivity. Ingesting, inhaling, or even coming into contact with cinnamon can cause an allergic reaction in sensitive individuals. It is essential for people with known cinnamon allergies of familial history to avoid the spice entirely and carefully read food labels to prevent accidental exposure.

Interactions with Medications

  1. Warfarin (Coumadin): Cinnamon may potentiate the anticoagulant effects of warfarin, increasing the risk of bleeding. This interaction is attributed to the presence of coumarin compounds in cinnamon, which can enhance the blood-thinning properties of warfarin. Patients taking warfarin should exercise caution when consuming cinnamon and discuss its use with their healthcare provider.
  2. Diabetes medications: Cinnamon has been shown to have potential blood sugar-lowering effects. When combined with diabetes medications such as insulin, metformin, or sulfonylureas, cinnamon may increase the risk of hypoglycemia (low blood sugar). Patients with diabetes should monitor their blood sugar levels closely when adding cinnamon to their diet.
  3. Hepatotoxic drugs: Cinnamon contains coumarin compounds, which have been associated with liver damage in high doses. When combined with medications that are known to be hepatotoxic (liver-damaging), such as acetaminophen, statins, or certain antibiotics, cinnamon may increase the risk of liver injury. Patients with pre-existing liver conditions or those taking hepatotoxic drugs should use cinnamon with caution.
  4. Cytochrome P450 substrates: Cinnamon is known to inhibit certain cytochrome P450 enzymes, particularly CYP3A4 and CYP2D6. These enzymes are involved in the metabolism of numerous medications, including some antidepressants, antipsychotics, and calcium channel blockers. Inhibition of these enzymes by cinnamon may lead to increased drug levels and potentially dangerous toxicity. Patients taking medications metabolized by CYP3A4 or CYP2D6 should be monitored closely when consuming cinnamon.

Dosage and Consumption Guidelines

Ceylon cinnamon, also known as "true" cinnamon, is generally considered safer for daily consumption due to its lower coumarin content, a compound that can be harmful to the liver in high doses. 

The recommended daily intake of Ceylon cinnamon is up to 5 grams (about 1 teaspoon) per day for adults. On the other hand, Cassia cinnamon, which is more commonly found in supermarkets, contains higher levels of coumarin. To avoid potential health risks, it is advised to limit the intake of Cassia cinnamon to no more than 2 grams per day for adults. 

Pregnant women and anyone with pre-existing liver conditions should be particularly cautious and consult their healthcare provider before consuming cinnamon supplements. 

Final Words

Cinnamon has the potential to make a significant difference in your life when used consciously and conscientiously. There is a real risk of overdosing yourself, and as highlighted, the adverse effects of it can be life-threatening.

That aside, if you are desirous of adding the spice to your daily plan, start at a low dose- but still be sure to run it by your pharmacist or physician to cover your bases.
