Should You Take a Carb Blocker? A few studies suggest carb blockers can help cause a small amount of weight loss, reduce appetite and lower blood sugar levels. However, studies haven't been high enough in quality to show whether carb blockers have any real long-term effect.

What blocks carbohydrate absorption?

Amylase inhibitors, also called starch blockers, prevent starches from being absorbed by the body. When amylase is blocked, those carbs pass through the body undigested, so you don't absorb the calories.

When should I take a carb blocker?

Take one to three tablets with a carbohydrate-containing meal. Do not exceed 9 tablets per day.
