The following review if for a product called 3-In-1 Carb Blocker, manufactured by Irwin Naturals. If you are eating a lot of carbohydrate-heavy foods such as bread, potatoes, and pasta, then this might be the right product for you. This product was designed by the manufacturer to help people like this with their triple-approach formula.

Read on to learn more about Irwin Naturals 3-In-1 Carb Blocker.

Ingredients & How It Works

  • Chromium
  • Flaxseed Oil
  • White Kidney Bean Extract
  • Cinnamon Extract
  • Lipase
  • Protease
  • Black Pepper Extract
  • Ginger Extract
  • Gelatin
  • Purified Water
  • Glycerin
  • Soy Lecithin
  • Beeswax
  • Annatto
  • Titanium Dioxide
  • Silicon Dioxide
  • St. John's Bread
  • Turmeric

White kidney bean extract is thought to be used as a 'starch blocker' as it inhibits the starch-digesting enzyme Amylase. This in turn prevents the starch that you eat from being turned into sugar and depositing in the body as fat. Chromium is also essential as it helps with the absorption of the white kidney bean extract, making it more effective. The product does however lack chitosan, which works in combination with chromium for optimal absorption.

Daily Serving

Adults are recommended to take 2 liquid soft-gels twice a day. These should be taken before a starchy meal or snack. It is suggested that users also follow a low calorie diet and exercise whilst taking this supplement, to insure the best results.

The amount of chromium found in this product is only 125 mcg, which is very much lower than the recommended and effective 1000 mcg. Such a low amount of chromium will reduce absorption and make this product less effective.

The Cost

Customers will pay $22.99 for a bottle of 75 liquid soft-gels, from the manufacturer's online purchase option. Unfortunately, the manufacturer does not offer discount on their product and they do not sell it in bulk.


After studying the manufacturer's website, we were unable to find any evidence of a money-back guarantee. A manufacturer must feel very confident about their product to provide a guarantee and lack thereof does not necessarily mean a bad thing. However, a first time customer does not want to pay for a product that does not deliver results. A return policy would be preferably, and lack thereof may make a customer search for an alternative option.

Our Review Summary Of Irwin Naturals 3-In-1 Carb Blocker

We do see a few positive aspects about Irwin Naturals 3-In-1 Carb Blocker. Firstly, the product contains the essential main active ingredient white kidney bean extract. The manufacturer also provides the customer with clear instructions on when and how it should be used.

However, we do also have a few negative aspects about the product. First of all, the product contains a very low concentration of chromium. This could make the product much less effective. Furthermore, the product does not contain chitosan, which works in combination with chromium to increase absorption. Thus, the lack of chitosan and the low concentration of chromium may reduce absorption of the white kidney bean extract, making it ineffective. Finally, there is no return policy provided by the manufacturer. These reasons indicate a low quality product that may not be effective and this is why we do not recommend Irwin Naturals 3-In-1 Carb Blocker.
