What is white Kidney Bean extract powder?

White kidney bean extract was the topic of a recent episode of Dr. Oz discussing "Fat Busters." The popular TV doctor said he found the research on white bean extract "absolutely compelling," and he was "confident in recommending it," especially for people trying to control their carbohydrate intake. The seeds of the White Kidney Bean plant (Phaseolus vulgaris) are most commonly used in the extract. This plant is native to Europe, the Indies and Peru. This extract acts as a starch blocker to block alpha-amylase enzyme.

Many studies have shown that White Kidney Bean interrupts the digestive process that converts starch to sugar, thus lessening the caloric intake from foods such as bread and rice. By reducing the absorption of these sugars, the body has fewer calories to store as fat. White Kidney Bean can be a very effective supplement for dieters and those interested in maintaining a healthy physique.



What if you could stop your body from turning starch into sugar, which would ultimately help prevent that excess sugar from being stored as fat? As it turns out, white kidney bean extract -- as discussed on tv -- slows digestion and blocks carbs from entering the bloodstream. This helps reduce the accumulation of fat in the belly, hips and thighs. Learn more about how white kidney bean can help you lose weight.

Blocking Enzymes
White kidney beans, also called cannelini beans, are a concentrated source of the compound phaseolamin. Phaseolamin, which is sold under the trade name Phase 2 or StarchLite, may aid weight loss by inhibiting the body's production of alpha-amylase, an enzyme involved in the digestion of carbohydrates. In 2007, the International Journal of Medical Science published the results of a study suggesting that phaseolamin significantly interferes with the digestion of starch, and that subjects who take phaseolamin were more significantly likely to lose weight than those who take a placebo. However, some early and "knock-off" forms of the supplement fail to inhibit enzymes reliably; most practitioners recommend only standardized extracts.

Carb Reduction
Theoretically, phaseolamin's enzyme-blocking powers reduce the number of carbohydrate-based calories that are absorbed and converted into body fat. Unable to break starches down into simpler sugars, the digestive system expels partially digested starches during bowel movements. A study conducted at the University of California theorized that phaseolamin inhibits or delays the digestion of complex starches, thereby reducing the overall weight and waist size of overweight participants. Though some fat-blocking counterparts such as orlistat (trade name Alli) produce unpleasant gastrointestinal side effects due to their enzyme-blocking activity, most clinical trials have demonstrated a relatively low incidence of diarrhea and stomach pain among phaseolamin users.

Reducing Glycemic Index
Because white kidney bean extract interferes with the absorption of carbohydrates and their conversion into simpler sugars, it may offer a potential treatment for diabetes and reactive hypoglycemia. Dr. Jay Udani--the medical director of Medicus Research and author of the 2007 University of California study of phaseolin--has suggested that the compound can lower the glycemic index of starchy foods such as white bread. By impairing the body's ability to derive glucose from these foods, phaseolin may prevent abrupt spikes in blood sugar and resulting complications. Additionally, routine supplementation may prevent or delay the onset of Type 2 diabetes in people with reactive hypoglycemia (pre-diabetes). Although these theoretical uses seem promising, they have not been investigated by large-scale clinical trials.


Benefits of taking white Kidney Bean extract powder supplement:

The benefits of white kidney bean extract are numerous, with the most notable being its ability to block starches. Many people become overweight due to the fact that starchy carbohydrate foods are often stored in the body as fat, to be used for energy at a later time.

White kidney bean extract may also be beneficial for lowering triglycerides, degenerative arthritis, coronary artery disease and obesity because of the ability it has to inhibit the body's digestion of complex carbohydrates.


white Kidney Bean extract powder Weight Loss

White kidney bean extract has the ability to block starches, so in effect it blocks the alpha-amylase enzyme, which plays an important role in digestion. Alpha-amylase is required for the metabolism of starchy carbohydrates, which are found in foods like potatoes, rice and pasta.

Complex carbohydrates must be broken down into smaller sections. These are known as dextrins. Dextrins are broken down even further, into glucose. Glucose is either used for current energy, stored in muscle tissue or the liver, or stored as body fat. White kidney bean extract will help some of the starches that would normally be stored as body fat to pass through the body undigested.

Many beans naturally contain a toxic compound that can cause fairly severe gastrointestinal upsets. However, this toxin can be eliminated through proper cooking. For this reason beans cannot be eaten raw. White kidney bean extracts undergo heat processing, which is effective in eliminating the toxin, making the extract safe to eat.

The above studies monitored subjects for side effects and none that were attributed to white kidney bean extract was reported (Celleno et al, 2007; Udani et al, 2004). A animal toxicological study showed that 1112 mg white bean extract/kg body weight/day for 4 weeks was safe (Chokshi, 2006). Another study suggested that 2500 mg/kg/day for 28 days could be the maximum safe dose (Chokshi, 2007). That's the equivalent of 200 g/day for an 80 kg man. White kidney bean extract is therefore deemed to be very safe for consumption.


white Kidney Bean extract powder Recommended Doses and Ingredient Timing

A dose of 445 mg white kidney bean extract/day may be adequate (Celleno et al, 2007), though higher doses have been used in trials (Udani et al, 2004). Because white kidney bean is a carb blocker, it should be taken before a meal. It can be done so before one or two meals/day. However, since white kidney bean can be found as part of a mixture of ingredients, it is important to follow the manufacturer's directions.


Stacking white Kidney Bean extract powder

White kidney bean can be stacked with many fat loss supplements. These include fat burners, fat metabolisers, and fat loss proteins. Together, they may provide an effective fat loss aid to help you achieve your goals.
