Sheer Block is a carb blocker from Sheer Strength Labs that has been designed to block the absorption of carbohydrates, increase fat burning, and reduce caloric intake which can “reduce cheat day damage”. The claim for this dietary supplement is that it is a “trusted” all-natural carb blocker that guarantees you’ll enjoy “real” results that you can “feel” and “see”.

The ingredients in Sheer Block include: White Kidney Bean Extract (445mg) and Green Tea Catechins (100mg) per 1 capsule serving.

The suggested use is to take 1 capsule per day with a full glass of water and users are cautioned not to exceed this dosage.


Sheer Block contains only two active ingredients, which means that you’re likely to get a significant dose of both unlike other weight loss supplements that contain numerous ingredients.

As for the ingredients themselves, some research has found that white kidney bean extract can help reduce starch absorption in humans and functions as an effective calorie and carbohydrate blocker. White kidney bean contains substances that interfere with amylase, an enzyme that is necessary to breakdown carbohydrates. If carbs are not broken down small enough they cannot be absorbed by the body, which means that the body cannot use the calories they provide. Absorbing fewer calories can help with weight loss.

As for green tea catechins, some research says that it can boost the amount of energy your body uses, which makes it easier to use excess fat. A daily dose of 270mg is said to be the most effective for producing these results.


When this review was written the official Sheer Strength Labs official site did not sell this product but it could be purchased on Amazon. This could mean that the manufacturer has stopped making the product.

There is no guarantee that taking this supplement will lead to the blocking of carbohydrates or that any fat burning improvements it makes to your life will actually result in measureable weight loss. There is not enough clinical evidence to prove that taking either white kidney bean extract or green tea catechins is safe or effective for weight loss.

Furthermore, research has found that 270mg of green tea catechins are effective, but you’ll receive only a 100mg daily dose with Sheer Block.

This product is not without side effects. White kidney bean is known for causing gastrointestinal side effects. It can also affect blood sugar or interact with medications designed to treat blood pressure. Since this is the case, individuals with diabetes should not take Sheer Block.

Prior to taking Sheer Block, it is in your best interest to consult with your medical practitioner. It is unwise to simply assume that this dietary supplement is safe to take for weight loss or for any other reason simply because it is “all-natural”.
