Formulation Notes

In a world where carbohydrate-dense snack foods, and starchy meals hold dominance over our taste buds, many of us face great difficulty in making daily food choices that serve our best interests. To help you take steps towards achieving your weight and metabolic health goals, we created Carb Neutralizer Starch-Blocker. This product features a targeted combination of ingredients that address key areas of physiology related to weight management: Decrease calories from carbohydrates - This formula features white kidney bean extract, a plant-derived non-stimulant ingredient that neutralized the negative effects of carbohydrates by inhibiting the enzyme responsible for digesting starches. This powerful plant extract works to decrease the number of starch-carbohydrate calories absorbed during digestion. Support blood sugar balance - Chromium plays an important role in supporting insulin function and promotes healthy blood sugar levels already within the normal range. Boost digestion of fats & protein - This formula includes digestive enzymes Lipase and Protease to help enhance the digestion of the other macronutrients your body needs for energy and cellular health maintenance. When combined with a healthy low-calorie diet and exercise plan, Carb Neutralizer Starch-Blocker provides a unique advantage to help you achieve your weight loss goals. What makes us different: Liquid Soft-Gels - The nutrients in these easy-to-swallow liquid soft-gels are released fast. Other forms of delivery can contain binders and fillers that may cause stomach upset and offer no nutritional value. Advanced Liquid Soft-Gels provide an optimum delivery system. Quality assurance - Irwin Naturals is committed to providing the highest quality products for your health. We employ compliance testing to ensure purity and potency.
