White kidney bean extract is a natural substance derived from the common bean, Phaseolus vulgaris. This extract is widely marketed as a dietary supplement. Its primary purpose is to influence the digestion of certain foods within the body.
Understanding Its Mechanism
The primary active compound in white kidney bean extract is an alpha-amylase inhibitor, also known as phaseolamin. This compound specifically targets the enzyme alpha-amylase, which is produced in the pancreas and salivary glands. Alpha-amylase is responsible for breaking down complex carbohydrates, such as starches, into simpler sugars like glucose, which the body can then absorb.
By inhibiting alpha-amylase, phaseolamin reduces the enzyme’s ability to break down these complex carbohydrates. As a result, a portion of the carbohydrates passes through the digestive tract undigested. This means fewer calories from these carbohydrates are absorbed into the bloodstream, and their impact on blood sugar levels is lessened. The undigested carbohydrates can then be excreted from the body or fermented by beneficial bacteria in the colon.
Key Health Applications
White kidney bean extract is primarily used for its potential role in weight management. By reducing the digestion and absorption of complex carbohydrates, it can lead to a decrease in the total caloric intake from meals. Research indicates that it may support modest weight loss, with some studies reporting a reduction of around 5 pounds over a period of 30 to 90 days. This effect is thought to be more pronounced when the supplement is combined with a diet that includes a reasonable carbohydrate intake.
Beyond weight management, this extract may also influence blood sugar levels. By slowing down the absorption of glucose from meals, it can help prevent rapid spikes in blood sugar, particularly after consuming high-carbohydrate foods. This mechanism could be beneficial for individuals seeking to manage their blood sugar response.
Potential Side Effects and Safety
White kidney bean extract can lead to common gastrointestinal side effects. These can include gas, bloating, and diarrhea. These symptoms often arise because undigested carbohydrates ferment in the colon, producing gas.
Certain individuals should exercise caution or avoid using this extract. Pregnant or breastfeeding individuals should avoid use due to lack of safety data. People with diabetes should consult a healthcare professional before taking white kidney bean extract, as it might lower blood sugar levels and could interact with diabetes medications.
Recommended Usage
White kidney bean extract is available in capsule or powdered forms. General guidance suggests taking it before carbohydrate-rich meals to maximize its effects on carbohydrate digestion. Dosages used in clinical studies have varied, ranging from 445 milligrams to 3,000 milligrams per day.
A common recommendation involves taking between 1,000 to 2,000 mg before high-carbohydrate meals, often divided into two doses per day. It is important to follow the specific instructions provided on the product label. Consulting a healthcare professional before starting any new dietary supplement is advisable, especially for individuals with existing health conditions or those taking other medications.
