What You Need To Know About CinSulin

CinSulin is a cinnamon extract that helps to regulate blood sugar levels by keeping them within a healthy range, typically by lowering them. It is not a medicine, and because of FDA restrictions the manufacturers are not allowed to state that it can treat diabetes. However, from the customer reviews, it is clear that the majority of customers who used the supplement are either diabetic or pre-diabetic.

What Are The Side Effects Of CinSulin?

CinSulin can lower blood sugar levels, and so diabetics should consult their doctor before purchasing this supplement, and should monitor their blood sugar levels closely whilst taking the supplement. Low blood sugar levels can cause the consumer to feel lightheaded, dizzy, and to feel faint. In extreme cases of hypoglycemia (severe low blood sugar levels), side effects can include seizures or convulsions (jerky movements) and even unconsciousness.

How Much Does CinSulin Cost?

If someone with pre-diabetes can get their blood sugar levels under control with a combination of dietary changes and taking CinSulin, then ultimately it is a very cheap alternative to having to pay for diabetes medication, should the issue remain untreated.

As the ingredient is available as a single ingredient supplement and as a part of multi-ingredient supplements, both from numerous different suppliers, the prices do vary significantly. Having said that, CinSulin products in general do appear to be very affordable.

Our Verdict On CinSulin

We have a mixed bag of opinions about CinSulin; on the one hand, if used correctly, this ingredient appears to be a promising way of lowering blood sugar levels, and could help to manage diabetes. On the other hand, the manufacturers have been very vague about the correct dosing of their supplement, with different branded products containing vastly different doses of CinSulin.

The product appears to be affordable, but consumers should remember to check the recommended daily serving- some brands offer excellent value whilst others require a high number of capsules to be taken each day, raising the cost of using the supplement in the long term.

No money-back guarantee is offered by the manufacturers, and consumers will have to look at the individual returns policies of the retailer they have purchased from.

Overall, we recommend that diabetics consult with their doctor before purchasing CinSulin. We do not recommend CinSulin as a weight loss aid, as there is no clinical support for this use.

The manufacturers of CinSulin describe the product and its benefits as follows:

CinSulin is a safe and effective dietary ingredient made with just water, heat and cinnamon. No harsh chemicals or solvents are used. It is the only patented water extract of cinnamon clinically studied to help maintain healthy blood sugar levels within the normal range.

Does CinSulin Work?

Overall, based upon both the available clinical evidence and the feedback from customer reviews, it seems that CinSulin does work to consistently lower blood sugar levels.

Whilst some individuals consider CinSulin to be a weight loss aid, there is not enough evidence to support this. It is possible that as CinSulin regulates blood sugar levels, it could help to reduce sugar crashes and sugar cravings, which are a huge factor in failed diets. However, there is not any evidence to support this, and even if it does work in this manner, the effects are likely to be small.

What Are The Ingredients of CinSulin?

CinSulin is a patented cinnamon extract. Several studies have found a link between cinnamon and the regulation of blood glucose levels, and it may play a small role in improving insulin sensitivity. In terms of its effects upon weight, this area has been under researched, but regulated blood sugar levels However, cinnamon could also stimulate the consumer’s appetite.

Some CinSulin products also contain other ingredients: Trunature Advanced Strength CinSulin, available from Costco and Amazon, contains 500 mg Water Extracted Cinnamon Plus 400 mcg Chromium Picolinate and 500 IU of Vitamin D3 per serving of two capsules.

Does CinSulin Have Any Side Effects?

Cinnamon can cause side effects such as lowered blood sugar, and when taken in large quantities it has been associated with worsened liver disease, thanks to a chemical called coumarin. A press release about CinSulin states that CinSulin contains very little coumarin compared to cinnamon, as coumarin has poor solubility in water.

Diabetics and pre-diabetics should consult their doctor before purchasing this supplement as Cinnamon can lower blood sugar levels. Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18.

Are There Any Customer Reviews For CinSulin?

There are numerous customer reviews for one CinSulin-containing product, Trunature Advanced Strength Cinsulin, on amazon where the product is sold. This supplement also contains chromium, which is also thought to help regulate blood sugar levels; results may not be the same with a supplement that just contains CinSulin without any additional ingredients. Some people found that the supplement did not affect their blood sugar levels, but they appear to be in the minority.

I’ve been using this product for some time now. If you make a serious attempt at eating properly, taking the meds and using CINSULIN, you’ll definitely see a drop in blood sugar numbers. I take two a day; in the morning and the evening and sometimes at midday when I’ve succumbed to a piece of cake. I am not recommending anyone to follow what I do, I am only sharing my experience with the product which has proven to be of great help in maintaining blood sugar levels between 90 and 120. I’d suggest you consult your physician about taking this product.

My blood sugar levels stay very consistent when I take this supplement. I have always had a difficult time keeping my levels consistent. I started taking this a little over a year ago. About a month after taking it daily as noted on the directions, my blood sugar levels became very consistent. I ran out once as I was getting it at Costco & they ran out I guess. My blood sugar levels started to vary significantly again after about 2 weeks. I found it here on Amazon & ordered some. About 3 weeks after starting again, my levels became very consistent again. This stuff works great for me.

I have pre diabetes and I was looking at the bottle in Costco, and an older man saw me looking at it, and came over and said how really well it worked for him. Well, I took my first pill this morning. I worked all day on a project, didn’t notice the time because I wasn’t hungry!!! That’s never happened to me before in my life. It must’ve regulated something! I wasn’t even ravenous for dinner!!!! I will see what happens tomorrow. I always used to complain to my dr that I didn’t metabolize well. Maybe this is it!!!

The product is fine. I’ve decided to eat the real thing and let those levels be enough for me rather than using a supplement.

The Cinsulin seems to help keep my blood glucose low. There has been improvement in my readings and A1c. As always check with your doctor before taking this. What works for one may not work for everybody.

Does CinSulin Offer a Money-Back Guarantee?

CinSulin is not sold directly by the manufacturers and so they do not offer any kind of money-back guarantee or returns policy.

Vitamin Research Products (, one of the third party retailers that sells a CinSulin supplement, offer what they call a “No Rush” Return Policy. They state on their website:

Where Can I Buy CinSulin?

CinSulin can be purchased either on its own, or as an ingredient in a multi-ingredient supplement. Because CinSulin is a patented ingredient, and not a branded supplement in its own right, the individual quantities found in each different supplement, and the recommended daily dosage, could vary immensely between individual products. offers a Cinsulin supplement, which contains 180 capsules per bottle. Each capsule contains 42 mg of CinSulin, and consumers are instructed to take 6 capsules per day, meaning that a single bottle will last for 30 days of use. There are numerous purchasing options, including a discount for bulk purchases, and a further discount for signing up to the website’s auto-ship program. A single bottle costs $21.95, whilst an order of three bottles costs $62.56 ($20.85 per bottle), and an order of six bottles costs $111.95 ($18.66 per bottle). Delivery charges may apply.

Customers signing up to the autoship program can make further savings; a delivery of three bottles every three months costs $55.97 ($18.66 per bottle), whilst a delivery of six bottles every six months costs $105.36 ($17.56 per bottle). We advise our readers to avoid auto-ship programs, as they can be difficult to cancel, can cost much more in the long run, and can be easy to forget about, especially when the product is only delivered once every three or six months.

Trunature Advanced Strength Cinsulin can be purchased from Costco, with a single bottle of 170 capsules costing $19.99 (plus delivery charges when ordered online).
