White Bean Extract

How Is White Bean Extract Used For Weight Loss?

Proponents claim that white bean extract can prevent alpha-amylase (an enzyme that occurs naturally in the body) from breaking down carbohydrates into glucose (sugar). By slowing up alpha-amylase activity, proponents suggest, white bean extract leaves behind less glucose for the body to turn into fat.


Additional Uses

Not only touted as a natural weight loss aid, white bean extract is said to keep blood sugar in check, fight insulin resistance, protect against diabetes and heart disease, enhance athletic performance, increase energy, ease symptoms of arthritis, and aid in the prevention of colon cancer.

Benefits of White Bean Extract

To date, there is limited research on the potential health benefits of white bean extract. However, some studies suggest that white bean extract may help promote weight loss. For instance, the authors of a research review published in Nutrition Journal in 2011 concluded that one proprietary white bean extract product (Phase 2 Carb Controller) may have the “potential to induce weight loss and reduce spikes in blood sugar caused by carbohydrates.”

One of the few clinical trials to test the health effects of white bean extract was published in the International Journal of Medical Sciences in 2007. The study involved 60 slightly overweight volunteers whose weight had been essentially stable for at least six months.

For 30 days, study participants took either 445 mg of white bean extract or a placebo daily (prior to consuming a meal rich in carbohydrates).

At the end of the 30-day period, researchers found that participants who had taken the white bean extract experienced a significantly greater reduction in body weight, fat mass, and waistline size (compared to members of the placebo group).

What’s more, white bean extract appeared to help the participants maintain lean body mass.

There is currently a lack of scientific evidence to support the use of white bean extract for any other health-related purpose.


Due to the lack of long-term clinical trials, little is known about the safety of taking white bean extract for an extended period. There’s some concern that use of white bean extract may trigger certain minor side effects (including nausea, bloating, gas, and diarrhea.

White bean supplements haven’t been tested for safety and keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established.
