Irwin Naturals Maximum Strength 3-In-1 Carb Blocker claims to be an all natural carbohydrate blocker that will help people who love carbs still lose weight, by prohibiting some of the carbohydrates you eat from passing into your body, getting digested, and converting to sugar. As this is not the only carb blocker on the market today, we will take a closer look to see what, if anything, about this one makes it better than the others available.

List of Ingredients

Irwin Naturals Maximum Strength 3-In-1 Carb Blocker contains: chromium, fish oil, white kidney bean extract, cinnamon, lipase, protease, and Bioperine black pepper extract.

Product Features

Irwin Naturals Maximum Strength 3-In-1 Carb Blocker contains many ingredients common to other dietary supplements on the market today. Chromium is thought to help stabilize blood sugar levels, to prevent cravings. Fish oil is a great source of essential fatty acids, which are thought to help remove fat from the body, but show insignificant results in studies. White kidney bean extract helps slow and prevent the absorption of starchy carbs. Cinnamon is thought to help burn fat and increase the metabolism. Lipase and protease are digestive enzymes. Bioperine black pepper extract is a concentrated version of the active ingredient in black pepper. It is thought to increase the bioavailabity and absorption of other ingredients it is used with. This product works three ways: increasing the metabolism, enhancing digestion, and reducing carbohydrate absorption. You should take two capsules, twice a day, with the meals containing starchy carbs, including: pasta, bread, and potatoes.

Then, use this product in conjunction with a balanced diet and regular exercise program. You will see great results, but should not rely on the supplement alone for weight loss.
