Carb blockers are supplements that inhibit the action of carbohydrate-digesting enzymes. As a result, some carbs pass through your digestive system without being digested or absorbed.
Carb blockers contain substances that inhibit the function of the digestive enzyme amylase, which is responsible for breaking down carbs into smaller molecules for digestion.
In addition, carb blockers may slow the digestion of other nutrients, such as protein and fat. This can also help reduce calorie intake.
Here are the top 10 carb blocker pills, capsules and supplements for 2019:
White Kidney Bean Extract (Starches)
Green Coffee Bean Extract
Carb blockers cannot eliminate all carbs from being digested and absorbed. However, research suggests that they may block enough carbs to produce modest weight loss in people with diabetes who are overweight or obese.
One study found that carb blocker supplements helped overweight diabetics lose an average of 2 7 lbs (0.9 3 kg) over 12 weeks.
Another study involving overweight people reported similar effects, causing subjects to lose 3 8 lbs (1.4 3.6 kg) over 6 weeks (44).
Similar results were seen in another study, in which healthy individuals who took a carb blocker lost 4 5 lbs (2 2.3 kg) more than those who didn't (45).
Carb blockers are usually taken as part of a weight loss program that includes a low-carb diet and regular exercise. However, they're not recommended for everyone.
Most carb blockers are made from the white kidney bean (Phaseolus vulgaris) extract. They contain alpha-amylase inhibitors, which slow down the breakdown of carbs in the intestine and reduce their absorption into the bloodstream.
The carb blockers sold as supplements usually contain concentrated extracts from white kidney beans. The active ingredients in these extracts, including phaseolamin, are referred to collectively as phase 2. Studies have shown that carb blockers containing phase 2 can prevent some carb absorption and stimulate weight loss (1Trusted Source).
However, more studies on humans are needed to confirm these effects. Moreover, while carb blockers have been shown to help with weight loss in the short term, their long-term safety is unknown.
Carb blockers are a form of weight loss supplement that claim to help reduce the amount of carbohydrates that the body absorbs. This can lead to weight loss and other health benefits.
They may also have other benefits, such as reducing blood sugar spikes after eating, lowering inflammation, and reducing the risk of heart disease.
Some studies show that these supplements may be helpful, but more research is needed. Here's a look at what carb blockers are and whether they're effective for weight loss.
HOW DO CARB BLOCKERS WORK?
Carb blockers target the enzyme alpha-amylase, which is produced in the pancreas and salivary glands. It functions to break down carbohydrates into simple sugars, so that they can be digested and used for energy. If you take a carb blocker before eating a meal containing carbs, the carb blocker will bind to alpha-amylase and stop it from working on the carbs. Without amylase, your body won't be able to convert many of these carbs into sugar. As a result, they'll pass through your digestive tract without being absorbed. That means you won't get any calories from them or experience blood sugar spikes after eating them!
There are two main types of carb blockers: Phase 2 carb blockers and white kidney bean extract carb blockers.
Phase 2 Carb Blockers
Phase 2 is a brand name for white kidney bean extract. White kidney beans have been shown to inhibit alpha-amylase activity in vitro (in a test tube), however, there have been few clinical studies done on the effectiveness of Phase 2 as a carb blocker.
