Phase 2 Carb Controller White Kidney Bean Extract
Also known as: White kidney bean, Common bean, Phase 2 Carb Controller, Phaseolus vulgaris
Overview
*Phaseolus vulgaris* L., commonly known as white kidney bean, is a legume that features a high concentration of alpha-amylase inhibitors. These compounds play a crucial role in reducing the enzymatic digestion of dietary starches, thereby influencing carbohydrate absorption. White kidney bean extract has gained popularity as a supplement for weight management and glycemic control. It is characterized by its non-stimulant nature, being solvent-free, and derived from non-GMO sources. This extract is suitable for vegan and gluten-free diets. The body of research supporting its effectiveness in promoting weight loss is moderately mature, encompassing several randomized controlled trials (RCTs) and systematic reviews that indicate potential benefits in reducing body fat and aiding glucose metabolism. However, the quality of the evidence varies, and it highlights the necessity for caution due to the disparity in study results.
Benefits
Research indicates that *Phaseolus vulgaris* extract can facilitate weight loss and enhance body composition. A randomized controlled trial showed significant weight loss of 2.24 kg over 35 days in participants using the extract versus a placebo group (p < 0.01). Furthermore, a systematic review revealed a notable mean difference in body fat reduction, favoring the extract (mean difference: -1.86 kg). Secondary benefits included a reduction in BMI by 0.79 and body fat by 1.53% compared to baseline. The most pronounced effects are seen in overweight or obese individuals, although there is early evidence supporting its role in stabilizing glucose levels post carbohydrate-rich meals. However, while statistically significant, the weight loss does not meet the usual clinical importance threshold of 5% body weight reduction, suggesting that the clinical relevance of such outcomes should be interpreted with caution.
How it works
The primary mechanism of *Phaseolus vulgaris* extract involves the activity of alpha-amylase inhibitors, which hinder the enzyme alpha-amylase responsible for digesting starches. This interference decreases carbohydrate absorption in the intestines, effectively lowering caloric intake and potentially supporting weight loss. Furthermore, this mechanism can influence blood sugar levels by moderating the impact of carbohydrate consumption, making it beneficial in maintaining healthy glycemic control, particularly after meals high in starches.
Side effects
Generally regarded as safe, *Phaseolus vulgaris* extract is associated with minimal side effects. Common adverse effects (occurring in more than 5% of users) include headaches, flatulence, soft stools, and slight constipation. Clinically, no significant differences in the frequency of these side effects were noted between the extract and placebo groups in studies. Uncommon side effects (1-5% occurrence) were not specifically documented, and no serious adverse events have been reported (<1%). Potential interactions with drugs affecting glucose metabolism necessitate caution, albeit there is limited evidence of notable drug interactions. While there are no specific contraindications, consulting a healthcare professional is advised for individuals with gastrointestinal conditions or those who are pregnant or breastfeeding.
Dosage
The effective dosage of *Phaseolus vulgaris* extract varies between studies, with recommended daily intakes ranging from 445 mg to 2400 mg. The Canadian Natural Health Products Directorate suggests a dose of 2000-3000 mg per day standardized to contain 3000 Alpha-Amylase Inhibiting Units (AAIU) per gram for optimal weight management. While the upper limit of safe dosage is not explicitly defined, trials utilizing doses up to 2400 mg have not demonstrated significant adverse effects. For best results, the extract should be consumed before meals, particularly the largest carbohydrate-rich meals. Various forms are available, including capsules and tablets, with effectiveness linked to its action in the digestive tract.
