White kidney bean extract
White kidney bean extract is otherwise known as Alpha – amylase inhibitor isoform 1. This substance is extracted from legumes. It has been found that it can block carbohydrates by inhibiting the digestion of starch (1), these carbohydrates are either excreted out of the body or fermented by colonic bacteria (2). It has been found that over long periods of time it can reduce body weight and body fat levels (3,4)
Garcinia Cambogia or hydroxycitric acid (HCA) as it is also known is a byproduct of citric acid. The benefits of HCA includes blocking fat and reducing cholesterol. HCA stops citrate lyase from converting various sugars and carbohydrates within the body to fat. This will also lead to a reduction of cholesterol. (5,6). Metabolism is also boosted as HCA can help balance chemical reactions within the body thus helping the process become more efficient (7).
Chromium has been found to help with the body’s insulin response (8).
