Carb blocker pills are said to support weight loss by preventing some of the carbohydrates you consume from being broken down and absorb by the body.
People take carb blocking diet pills to help them suppress their appetites, lose weight, better manage blood sugar, and reduce risk factors for diabetes. These supplements are also being researched for their anti-cancer effects.
There are various types of carb blocker supplements, but only those which contain Phaseolus vulgaris (White Kidney Bean) extracts have been widely researched.
Phaseolus vulgaris is a species of common beans which includes green beans, cannellini beans, kidney beans, pinto beans, cranberry beans and several other varieties. They are all legumes and all contain a compound called phaseolamin.



- Helps reduce the absoprtion of carbohydrates
- Suppresses the appetite & feel full
- May promote weight loss in a healthy diet
How do Phaseolus vulgaris Carb Blocker Pills Work?
Related Topics
Phaseolamin-based carb blocker pills work by inhibiting the actions of a digestive enzyme called alpha amylase isoform 1 (Alpha AI1).
It is released by the pancreas to break down long-chain carbohydrate food sources when they reach the small intestines during the digestive process.
When carb blocker pills are ingested, Alpha AI1 is suppressed and the long-chain carbs fail to be broken down. This means they pass through to the colon without being metabolized. Since they not digested, no caloric value is gained from them.
Taking a carb blocker pill can help to achieve weight loss in a manner similar to restricting caloric intake. Some users report decreased appetites, being satiated with less food, weight loss and certain other benefits.
Uses for Carb Blocker Pills
The Natural Medicines Comprehensive Database states that phaseolamin-based carb blocker pills are used for lung cancer, diabetes, hypercholesterolemia, kidney stones, bladder stones, urinary tract infections (UTIs), obesity and weight loss. They are also useful as diuretic agents.
Currently, the FDA has not approved White Kidney Bean extract as a medication for the treatment of any specific health condition or disease. While there have been promising initial results for weight loss, the hypothesized effects on cancer and other medical diseases need further study.
Carb Blocker Pills for Obesity and Weight Loss
Most people use carb blocker pills to help them lose weight. In theory, blocking the digestion of carbohydrates induces the same results as not eating the carbs in the first place.
Some research shows that proper oral usage of a phaseolamin supplement can help to decrease body weight and waist circumference, but not hip circumference.
In one study, treatment subjects were given 1000 mg doses of phaseolamin carb blocker pills three times daily for two months.
Relative to controls, modest improvements were noted concerning body weight and waist circumference. Treated patients lost an average of 4.19 pounds while control subjects lost only 0.89 pounds.
Average weight losses of less than 3 pounds demonstrates that using a carb blocker pill to lose weight should never be a first-line strategy.
Long-term success with weight management can only be accomplished by carefully choosing your foods, getting regular exercise and engaging other healthy lifestyle habits.
Phaseolamin Carb Blocker Pills for Diabetes
Research shows that Phaseolus vulgaris carb blocker pills can be helpful for managing long-term symptoms of diabetes mellitus type 2.
Many users report decreases in blood-glucose spikes, especially after carbohydrate-heavy meals. By improving the utilization of glucose, insensitivity to insulin may be decreased.
In one study, patients with type 2 diabetes were treated with a combination supplement containing P. vulgaris, white mulberry and bilberry extracts.
Taking 15 grams three times daily for sixty days resulted in a 24.3% average decrease in blood glucose levels.
Some user reviews of carb blocking diet pill report reversing prediabetes and type 2 diabetes symptoms and no longer needed to use traditional medicines prescribed for Metabolic Syndrome.
Carb Blockers & Cholesterol
Excessive accumulations of triglycerides (hypertriglyceridemia) and LDL cholesterol (hypercholesterolemia) can cause the formation of arterial plaque inside circulatory vessels.
Left untreated, this plaque causes the arteries to become clogged (atherosclerosis). This may subsequently lead to coronary artery disease, heart disease, stroke and/or death.
Routine supplementation with a phaseolamin carb blocker pill can help to reduce fatty acid buildups and decrease the risks of developing cardiovascular dysfunction and disease.
One open-label study evaluated the long-term effects of White Kidney Bean extract supplementation on serum lipids and fecal excretion of fats.
62 overweight/obese subjects were randomly assigned into treatment and placebo groups. Subjects were 21 males and 42 females between the ages of 22 and 66.
Results after three months showed significant decreases in the serum cholesterol levels of treatment group subjects, but not in those of controls. After nine months, LDL-C decreased as well as total cholesterol in treatment subjects.
Triglyceride counts were not changed in either group. Fecal fat excretion was also increased significantly in the treatment group.
By improving lipid balances and increasing fat excretion in feces, phaseolamin carb blockers may help to improve long-term cardiovascular health, especially in overweight and obese individuals.
Carb Blocker Pills Side Effects
A small percentage of carb blocker pill users experience gastrointestinal side effects including nausea, vomiting, diarrhea, gas and/or bloating. Usage is normally well tolerated in healthy adults.
Carb blocker pills are not rated for safety in pregnant or nursing women. Because they possess hypoglycemic potentials, usage is not recommended in combination with antidiabetic medications and/or herbal supplements.
Stop using White Kidney Bean extracts at least 14 days before any scheduled surgeries. Check with your doctor for other contraindications and risk factors related to the use of diet pills.
