White Beans ExtractCredit: Nutricap LabsHow do you take the calories out of a potato without taking the potatoes out of your low-caloric diet? Apparently, eating potatoesshould no longer be a guilty pleasure enjoyed sparingly. There’s good news for carb addicts, couch potatoes and avid potato lovers. An astounding discovery has led scientists to conclude that a carbohydrate-inhibitor found in common white beans(Phaseolus vulgaris) may significantly inhibit the digestion of carbohydrates found in foods like rice, pasta, white bread and potato—foodsthat make uphalf the caloric content in an average American diet.

White Bean Extracts – Natural Starch Inhibitors
In a research study led by Jay Udani, MD of the UCLA School of Medicine, 50 obese adults were administered a natural starch-neutralizing supplement (1,500 mg twice daily) containing white bean extract for 8-weeks. All participants followed a low-fat diet. At the end of the study, those who took the starch-neutralizing supplement were observed to have lost an average of 3.8 pounds; those without the supplement lost an average of 1.65 pounds. Researchers concluded that white bean extractsmay help to block a key enzyme,alpha amylase, responsible forthe breakdown of starches and sugarsinto glucose. Glucose is then converted to energy by the body or stored as fat. When alpha amylase isblocked, complex carbohydrates pass undigestedthrough the gastrointestinal tract thus preventing caloric absorption.1

Alpha-amylase inhibitors were first discovered in plants such as wheat and beans in the 1940s. It was only in the 1970s that researchbegan to focus specifically on the carb-lowering abilities of these plants. Since then, a growing body of research on plant-based ingredients that lower the rate of carbohydrate absorption through enzyme-inhibitingactivityhas been hitting the media and sweeping consumer interest.2Popularized by notable, celebrity doctors such as Dr. Oz, natural carb/calorie blockers are becoming popularamongst ardentweight loss watchers and are driving the weight loss ingredients market.

The Benefits of White Bean Extracts
Starch-neutralizing (white bean extracts) supplements can provide benefits to billions of people around the world battling obesity and related health concerns such as diabetes, cardiovascular disease and metabolic syndrome. Here is what these studies have to say: 3-8

  • Alpha-amylase inhibitors found in white bean extracts show potential ability to induce weight loss by reducing caloric intake.
  • White bean extracts help regulate healthy blood sugars after a rich carbohydrate diet by reducing the glycemic index of foods. Data from studies show that alpha-amylase inhibitors have the potential ability to reduce the post-prandial spike in blood glucose levels.

    According to a 2009 HealthFocus Trends Study, the percentage of adults using supplements to manage their blood sugar levels was 6% representing a growth of 44% from the previous year. A low glycemic is associated with lesser risk of diabetes and cardiovascular disease.9
  • White bean extractsshow ability to convert starches into resistant starches resulting in extended benefits. According to several studies, resistant or undigested starches pass to the colon where they are fermented into short chain fatty acids, organic acids, carbon dioxide, and hydrogen. The chemical reaction that takes place in the fermentation process is responsible for producing nutrients known to have positive implications for weight loss, blood lipid improvement, glycemic control and antioxidant protection.

Rising Sales of Weight Loss Ingredients
The weight loss industry continues to grow as more people in the United States and around the world struggle with their weight. Even as governments adopt measures to control obesity, the statistics don’t budge, pushing scientific research on slimming ingredients to new boundaries. This has resulted in a variety of weight loss products consumers are eager to try in combination with their own weight management regiments. Weight loss ingredients are marketed under six categories—thermogenesis, inhibiting protein breakdown, appetite suppressants, fat blockers, carbohydrate blockers, and mood regulators. Those interested in contract manufacturing nutritional supplements should consider fat burning or calorie blocking products since they hold the highest growth potential, according to Datamonitor.10

Frost & Sullivan reports the global market for weight loss ingredients grew 7 percent in 2009, and was valued at $7.5 billion. Showing no signs of decline, the global market research company predicts this market will grow to $13.9 billion by 2015. According to Frost & Sullivan’s 2010 report “Opportunities in Global Weight Management Ingredients” this market would enjoy greater growth prospects if consumers received more education about the specific ingredients in the product and their benefits for weight loss.11

Manufacturing white bean extract supplements
White bean extract can be manufactured in a variety of nutritional supplement forms such as powders, capsules and tablets. A specifically processed extract of Phaseolus Vulgaris is available under the branded name Phase 2. Clinical trial and testingof Phase 2 have shown positive weight loss benefits by decreasing intestinal carbohydrate intake. Data from studies show that the powder form may be more effective than capsules because of its higher bio-availability.12

With more consumers seeking science-based products for management of weight and healthy glycemic index levels, supplement business owners should considerproviding these benefits to their customers bymarketing their own brand of white bean extract supplements. Contract manufacturing dietary supplements with a GMP-certified supplement manufacturer will simplify the entire process and provide you with high-quality weight loss products using science-based formulations—weight loss supplements you’ll be proud to put your label on!
