Also known as: White Kidney Bean Extract, Phaseolus vulgaris extract, Phaselus vulgaris, Phaseolin, Phaseolus vulgaris (White Kidney Bean Seed Extract)

Overview

White kidney bean seed extract is derived from the seeds of Phaseolus vulgaris, recognized for its high dietary fiber and protein content. This extract is notable for its potent α-amylase inhibitory activity, which significantly reduces carbohydrate digestion and absorption. This characteristic makes it beneficial for weight management and metabolic health. The primary active compound, phaseolin, is a glycoprotein that underlies the extract's effectiveness. Numerous high-quality randomized controlled trials and systematic reviews have validated its efficacy in promoting weight loss and improving metabolic parameters in overweight and obese individuals. Typically available in capsule or pill form, it is frequently used by individuals who aim to lose weight without having to make extensive dietary changes.

Benefits

1. **Weight Loss**: Systematic reviews indicate significant weight reduction of about 2.93 kg (approximately 3.79 lbs) when using white kidney bean extract compared to placebo, achieving statistical significance (p < 0.001) over 30 days to 12 weeks. 2. **Metabolic Health**: Improved glucose tolerance and reduced insulin resistance have been shown in animal studies. 3. **Reduced Carbohydrate Absorption**: The extract aids blood glucose regulation by inhibiting α-amylase, which decreases carbohydrate absorption. 4. **Gut Microbiota Modulation**: Preliminary evidence suggests potential benefits to gut microbiota, warranting further research for clinical validation. These benefits are especially pertinent for individuals dealing with overweight and obesity, seeking health benefits with minimal dietary adjustments.

How it works

White kidney bean extract primarily inhibits α-amylase, the enzyme responsible for breaking down starches into simple sugars in the small intestine. By thwarting this enzyme's action, the extract reduces carbohydrate digestion and absorption, thus helping to maintain lower blood sugar levels. The active component, phaseolin, travels through the gastrointestinal tract, providing both local digestive benefits and broader systemic metabolic effects.

Side effects

White kidney bean extract is generally regarded as safe, with minimal adverse effects reported in fewer than 5% of users. No uncommon side effects have been recorded. However, individuals on diabetes medications should exercise caution due to the limited evidence regarding potential interactions. While specific contraindications are lacking, those with severe gastrointestinal disorders are advised to consult with healthcare professionals prior to use. Pregnant or breastfeeding women should also seek medical guidance, given the insufficient research on this demographic. Clinical trials have consistently indicated a favorable safety profile and good user tolerance.

Dosage

The generally recommended dosage for white kidney bean extract is around 445 mg daily, ideally taken before meals high in carbohydrates. For enhanced efficacy, higher doses of 800 to 1,000 mg per day can be divided across two to three doses within a maximum duration of 12 weeks. While human studies suggest maintaining intake below 1,000 mg/day, some animal studies indicate safety at doses up to 4 g/kg/day. Timing is crucial; taking the extract before meals optimally inhibits carbohydrate digestion. It is commonly available in capsule or pill forms, and its absorption may vary due to interactions with other nutrients.
