White kedney extract is a kind of botanical extract. The White Kidney Bean plant has been used for thousands of years.
While white kidney bean extract promotes healthy weight management and healthy weight loss, and is currently the best starch blocking product developed, it is not a "magic pill" for weight loss or weight management (indeed, no magic pill exists). Therefore, continuing to limit your starch intake is recommended when using white kidney bean extract. Some nutritional supplement manufacturers have claimed that white kidney bean extract is more lipogenic (fat loss causing) than Ephedrine HCL. Ephedrine HCL is a very potent CNS stimulant (a beta agonist) that promotes rapid fat and water loss.
