Cinnamon is a fragrant and delicious spice commonly used in baking muffins, pies, and delicious sweet treats like cinnamon rolls. Yet, did you know that popular spice may also have health benefits?
Recent clinical studies revealed that a particular patented cinnamon extract (called CinSulin) may have some benefits for your health, primarily in supporting weight management and lowering blood sugar in people with diabetes.
1) CinSulin at a Glance
CinSulin is a patented cinnamon extract that claims to support weight loss, lower blood sugar, and reduce body fat. It’s currently included in several different weight loss supplements, all of which feature this ingredient as its main additive.
Unlike the whole cinnamon extract used in most cinnamon supplements, which is just ground-up cinnamon bark, CinSulin’s patented process uses a 100% water solvent to produce a pure and unadulterated extract of cinnamon that ensures the highest quality[1].
Our review will analyze the supplement made by TruNature, as it’s one of the most popular CinSulin-based dietary supplements available.
2) History of CinSulin
CinSulin dietary supplement is produced by TruNature, a Costco Wholesale Corporation’s trademark[2] in Issaquah, WA, 98027.
TruNature is known for producing and selling a variety of products, from skincare products to dietary supplements for children, men, and women.
Some of its best selling supplements include:
- Vision Complex with Lutein & Zeaxanthin
- Saw Palmetto Prostate Health Complex
- Digestive Probiotic
- TruNature Ginkgo Biloba
- Advanced Strength Cinsulin
- Grape Seed and Resveratrol
- Premium Turmeric 1000 mg
- Prostate Plus Health Complex
- Cran-MAX Cranberry 500 mg
- One Per Day Cranberry 650 mg
Because TruNature is a trademark of Costco Corporation, the company doesn’t have its customer support department. You will have to contact Costco’s customer support service (phone: 1 (800) 774-2678) for any inquiries regarding TruNature and its products.
3) Ingredients of CinSulin
CinSulin includes the following active ingredients:
- Cinnamon Bark Extract 10:1 (CinSulin) 500 mg
- Chromium (from Chromium Picolinate) 400 mcg
- Vitamin D3 12.5 mcg
Other ingredients include hypromellose, cellulose, silicon dioxide, and magnesium stearate.
4) Is CinSulin Right for You?
CinSulin is the result of a unique manufacturing process that uses purified water, cinnamon bark, heat, and pressure to form a water-soluble extract. According to TruNature, CinSulin contains only the beneficial substances found in cinnamon in a highly concentrated water-soluble compound.
Possible harmful fat-soluble elements, like coumarin, are removed during the manufacturing process.
If cinnamon is part of your healthy blood glucose regimen or your weight management program, CinSulin may have another advantage. Due to the high amounts of cinnamon available in just one CinSulin capsule, in theory, you will save money.
As for benefits, CinSulin and cinnamon pretty much share the same health benefits.
In Ayurvedic medicine, cinnamon is used as a remedy for indigestion, diabetes, colds, and to help balance a person’s ‘Kapha’ (physical and emotional energies). It is also a common ingredient in cinnamon tea and chai tea, both of which are believed to improve digestion[3][4].
Extracts from the bark, leaves, flowers, fruits, and roots of the cinnamon tree have been used in traditional medicine for millennia to treat nausea, diarrhea, colds, painful menstrual periods, and flatulence. It is also believed to improve circulation, vitality, and energy, particularly in individuals with cold feet[5].
One of the most important active ingredients in cinnamon is a substance called cinnamaldehyde[6]. Cinnamaldehyde gives cinnamon its specific taste and smell, and it may also be responsible for some of cinnamon’s possible health benefits.
Some research shows cinnamon may lower blood sugar levels and have a powerful anti-diabetic effect[7][8].
Numerous human studies[9][10][11] have confirmed cinnamon’s antidiabetic effects, showing that it can lower fasting blood sugar levels by 10–29%.
Cinnamon may also have beneficial effects on neurodegenerative diseases[12][13] characterized by progressive loss of brain cells’ function or structure.
Parkinson’s and Alzheimer’s disease are two of the most common types of neurodegenerative diseases.
Two compounds found in cinnamon appear to inhibit the buildup of a protein called ‘tau’ in the brain, one of Alzheimer’s disease signs.
In a study[14] in mice with Parkinson’s disease, cinnamon helped protect neurons, improved motor function, and normalized neurotransmitter levels. These effects need to be analyzed further in humans.
Other cinnamon claimed benefits[15][16][17][18][19] include:
- It contains powerful antioxidants, which makes cinnamon a “superfood”;
- It has anti-inflammatory properties;
- May reduce the risk of heart disease;
- It can improve sensitivity to the hormone insulin;
- It may protect against cancer
- Helps fight bacterial and fungal infections
However, many of the studies supporting the claims above have been done in cells or animals.
Cinnamon does have anti-inflammatory, antibiotic, and antioxidant properties, but for now, there isn’t enough scientific evidence to prove it works that well in people.
Furthermore, consuming regular amounts of cinnamon isn’t likely to have a significant impact on your health. It’s not a good idea to eat a lot of it either. But that’s where the highly concentrated cinnamon extract, CinSulin, could make a difference.
5) CinSulin Health Benefits
CinSulin claimed benefits include:
- Cinnamon concentrate 10:1 strength promotes sugar metabolism for healthy blood glucose levels (within the normal range);
- Trunature CinSulin offers cinnamon in its purest, safest, and most potent form;
- Contains Chromium, which has a long history of helping to maintain healthy blood sugar levels in the normal range;
- Contains Vitamin D3 that plays a vital role as a nutrient that is deficient in many people looking to manage their blood glucose levels within a normal range.
6) Side Effects of Using CinSulin
The National Center for Complementary and Integrative Health (NCCIH)[20] states cinnamon supplements should be safe for most people when adequately dosed.
If consumed in high doses, cinnamon can cause mild sweating, indigestion, and heartburn. Over time, coumarin accumulation in the body can lead to liver damage and impede blood clotting.
Cinnamon can also trigger mild to moderate allergic reactions in some individuals. Symptoms can include nausea, rash, dizziness, or nasal congestion.
7) CinSulin Warnings and Precautions
We recommend caution if you also take other supplements that lower blood sugar levels[21], including:
- Alpha-lipoic acid
- Bitter melon
- Chromium
- Devil’s claw
- Fenugreek
- Garlic and garlic extracts
- Horse chestnut
- Panax ginseng
- Siberian ginseng
- Psyllium
The same holds true with diabetes medications[22]. Some medications used for diabetes include:
- Glyburide (DiaBeta, Glynase PresTab, Micronase)
- Glimepiride (Amaryl)
- Pioglitazone (Actos)
- Insulin
- Chlorpropamide (Diabinese)
- Rosiglitazone (Avandia)
- Tolbutamide (Orinase)
- Glipizide (Glucotrol)
Taking substantial doses of cinnamon might harm the liver, especially in people with existing liver disease. Cinnamon may also interact with certain medicines that may damage the liver[23].
8) Where to Buy CinSulin
CinSulin can be purchased from all major online retailers like Costco, Amazon, Walmart, and eBay. It’s also available in many local stores and supermarkets.
9) How Much Does CinSulin Cost?
CinSulin is available in two forms:
- Advanced Strength 170 capsules (85 servings) for $29.99
- Advanced Strength 200 capsules (100 servings) for $34.99
10) How to Take CinSulin
As a dietary supplement, take two (2) capsules once daily with water during a meal.
11) What Users Are Saying
"My dad raves about this product. He is vegetarian and before we had to open up all the capsules so he could eat them. He's noticed a huge reduction in his blood glucose. He monitors his blood sugar every morning when he wakes up, and on days he doesn't take it, his fasting glucose is 120, but when he does take it, his fasting is 100." [Read full review]
---Emily F.
"It helps keep my sugar levels at a more normal amount. I am borderline diabetic right now and cannot handle the metformin medication the doctor wanted me to take. This product is fantastic." [Read full review]
---Angela

---Brian H.
12) Our Final Take On CinSulin
Extensive clinical studies suggest that the compounds in cinnamon have antimicrobial, antioxidant, antidiabetic, and anti-inflammatory properties, and that they might offer protection from cardiovascular disease and cancer, among other conditions.
CinSulin has also been studied in human clinical trials and has been found to be safe and more effective than a standard cinnamon extract. However, while these initial findings are encouraging, additional research is required to determine all the long-term benefits of CinSulin.
Overall, CinSulin is a well-received dietary supplement, and it can be a good choice for people looking for a natural way to lower blood sugar levels and burn fat.
If you are interested in taking CinSulin, we recommend integrating the supplement as part of a healthy lifestyle that includes staying active daily, a healthy eating regimen, and getting at least eight hours of sleep each night.
