No Comments

TruNature CinSulin is a potent cinnamon extract used to promote healthy blood sugar levels in the normal range. While many companies are selling similar cinnamon-based supplements, this review will analyze the product made by TruNature.

In short, our CinSulin review will analyze its benefits, claims, who is supposed to help, potential side effects, warnings, effectiveness, real customer testimonials, and best stores to buy it from.


CinSulin is a concentrated cinnamon extract designed to promote sugar metabolism for healthy blood glucose levels. 

The highly concentrated cinnamon extract is obtained during a unique technological process that puts cinnamon bark through a water extraction process, increasing its safety and effectiveness as a supplement. The resulting concentration of 10:1 means that two 250 mg capsules contain the desirable compounds found in ten 500 mg capsules of table cinnamon.

Who Makes It?

CinSulin is made by TruNature, a trademark of Costco Wholesale Corporation. Besides this dietary supplement, TruNature is known for developing and selling a wide range of supplements for men, women, and children. 

Some of their best selling products include Advanced Digestive Probiotic, Vision Complex, CoQ10, Grape Seed & Resveratrol, Premium Turmeric, Triple Strength Omega-3, and Prostate Plus Health Complex.

TruNature CinSulin Ingredients

TruNature CinSulin contains the following active ingredients per serving (2 capsules):

  • Vitamin D3 12.5 mcg (500 IU)
  • Chromium (from Chromium Picolinate) 400 mcg
  • Water extracted Cinnamon Bark Extract 10:1 (CinSulin) 500 mg.

Inactive ingredients include cellulose, hypromellose, magnesium stearate, and silicon dioxide. 

The formula does not contain gluten, wheat, sugar, lactose, milk, fish, common allergens, artificial flavors, central nervous system stimulants, or caffeine. 

Cinnamon has grown in popularity in dietary supplements. It has been linked with health benefits like improved blood sugar control and lowering of some risk factors for heart disease.

What’s the Difference Between CinSulin and Cinnamon?

Most cinnamon dietary supplements contain cinnamon bark powder (finely grounded cinnamon, similar to what you can usually find in most kitchen spice racks). This powder usually contains everything in the cinnamon plant, from fat-soluble compounds to water-soluble compounds in varying amounts.

Fat-soluble compounds are generally not good for your health. They may even be downright harmful when taken in large amounts for extended periods.

On the other hand, water-soluble compounds (like the ones used in CinSulin) are beneficial. According to TruNature, cinnamon is processed using a patented water extraction process that separates the beneficial compounds from the unwanted fat-soluble compounds. Utilizing a 100% water solvent, the company can produce a pure and unadulterated cinnamon extract that ensures the highest quality.

Who Is CinSulin For?

TruNature CinSulin is marketed towards healthy adults who wish to support their normal weight and blood sugar levels as part of a healthy diet and exercise routine through the cinnamon plant’s beneficiary compounds.

TruNature CinSulin Side Effects & Warnings

Because the water extraction process removes the potentially dangerous compounds from cinnamon, CinSulin is advertised as safe to use with no reported side effects.

Regardless, we always recommend caution when using dietary supplements, even natural ones. 

Consuming large amounts of cinnamon (way above the recommended daily dose) may cause moderate to severe adverse effects, including liver damage, increased risk of cancer, mouth sores, low blood sugar, and breathing problems. 

Cinnamon may also interact with certain medications for diabetes, heart disease, or liver disease.

Bottom Line

TruNature CinSulin may be the right choice for anyone interested in supporting healthy blood sugar metabolism. Because of the unique water extraction process, CinSulin is safer than the average cinnamon-based supplements, while offering very similar benefits. 

However, due to the potential interactions cinnamon may have with certain prescription medications, we recommend discussing with your healthcare provider before taking this supplement. This is especially important for people taking other medications or supplements that might affect blood sugar.
